Ben Skeggs 586c55f6ad drm/nouveau: have non-core mmio accesses go through device object
Adds an extra layer of indirection to each register access, but it's not
too bad, and will also go away as pieces are ported.

Ben Skeggs 9458029940 drm/nouveau: implement module init functions in nouveau_drm.c
These currently just call the existing ones in nouveau_drv.c, but will be
extended in upcoming commits.  This needed to be separated from the current

Ben Skeggs 9274f4a9ba drm/nouveau/core: pull in most of the new core infrastructure
This commit provides most of the infrastructure to support a major overhaul
of Nouveau's internals coming in the following commits.  This work aims to
take all the things we've learned over the last several years, and turn that
into a cleaner architecture that's more maintainable going forward.

RAMHT and MM bits of the new core have been left out for the moment, and
will be pulled in as I go through the process of porting the code to
become either subdev or engine modules.

There are several main goals I wanted to achieve through this work:

-- Reduce complexity

The goal here was to make each component of the driver as independent as
possible, which will ease maintainability and readability, and provide a
good base for resetting locked up GPU units in the future.

-- Better tracking of GPU units that are required at any given time

This is for future PM work, we'll be able to tell exactly what parts of the
GPU we need powered at any given point (etc).

-- Expose all available NVIDIA GPUs to the client

In order to support things such as multi-GPU channels, we want to be able
to expose all the NVIDIA GPUs to the client over a single file descriptor
so it can send a single push buffer to multiple GPUs.

-- Untangle the core hardware support code from the DRM implementation

This happened initially as an unexpected side-effect of developing the
initial core infrastructure in userspace, but it turned into a goal of
the whole project.  Initial benefits will be the availablility of a
number of userspace tools and tests using the same code as the driver
itself, but will also be important as I look into some virtualisation
ideas.

v2: Ben Skeggs <bskeggs@redhat.com>
- fix duplicate assignments noticed by clang
- implement some forgotten yelling in error path
- ensure 64-bit engine mask is used everywhere

v3: Marcin Slusarz <marcin.slusarz@gmail.com>
- sparse fixes
- inline nv_printk into nv_assert to prevent recursive inlining issues

v4: Ben Skeggs <bskeggs@redhat.com>
- fixed minor memory leak on gpuobj destruction

Ben Skeggs 02a841d434 drm/nouveau: restructure source tree, split core from drm implementation
Future work will be headed in the way of separating the policy supplied by
the nouveau drm module from the mechanisms provided by the driver core.

There will be a couple of major classes (subdev, engine) of driver modules
that have clearly defined tasks, and the further directory structure change
is to reflect this.

No code changes here whatsoever, aside from fixing up a couple of include
file pathnames.

Ben Skeggs 3a92d37e40 drm/nouveau/gem: use bo.offset rather than mm_node.start
Won't necessarily be a drm_mm_node in the future, and I can't think of any
good reason to not use the offset from the bo struct.  There may have been
some reason once apon a time, but, separate commit just in case.

Ben Skeggs d6ba6d215a drm/nvc0/fence: restore pre-suspend fence buffer context on resume
Fixes some unfortunate races on resume.  The G84 version of the code doesn't
need this as "gpuobj"s are automagically suspended/resumed by the core code
whereas pinned buffer objects are not.

Linus Torvalds ca41cc96b2 Merge branch 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and DMA-mapping updates from Marek Szyprowski:
 "This time the pull request is rather small, because the further
  redesign patches were not ready on time.

  This pull request consists of the patches which extend ARM DMA-mapping
  subsystem with support for CPU coherent (ACP) DMA busses.  The first
  client of the new version is HighBank SATA driver.  The second part of
  the pull request includes various cleanup for both CMA common code and
  ARM DMA-mapping subsystem."

Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.

Merge tag 'spi-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc

Pull spi updates from Mark Brown:
 "No framework work here, only a bunch of driver updates of varying
  sizes:

   - Factoring out of the core hardware support from the MXS MMC driver
     by Marek Vasut to allow the hardware to also be used for SPI.
   - Lots of error handling cleanups from Guenter Roeck
   - Removal of the existing Tegra driver which is quite comprehensively
     broken as detailed in the changelog for the removal.
   - DT suppport for the PL022 and GPIO drivers.
   - pinctrl support for OMAP and PL022."

This merge also removes a new use of __cancel_delayed_work(), and
replaces it with the regular cancel_delayed_work() that is now irq-safe
thanks to the workqueue updates.

That said, I suspect the sequence in question should probably use
"mod_delayed_work()".  I just did the minimal "don't use deprecated

Linus Torvalds 916082b073 workqueue: avoid using deprecated functions
The network merge brought in a few users of functions that got
deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the
same as the regular system_wq, since all workqueues are now non-
reentrant.

Similarly, remove one use of flush_work_sync() - the regular
flush_work() has become synchronous, and the "_sync()" version is thus
deprecated as being superfluous.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

Linus Torvalds 437589a74b Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
 "This is a mostly modest set of changes to enable basic user namespace
  support.  This allows the code to code to compile with user namespaces
  enabled and removes the assumption there is only the initial user
  namespace.  Everything is converted except for the most complex of the
  filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,
  nfs, ocfs2 and xfs as those patches need a bit more review.

  The strategy is to push kuid_t and kgid_t values are far down into
  subsystems and filesystems as reasonable.  Leaving the make_kuid and
  from_kuid operations to happen at the edge of userspace, as the values
  come off the disk, and as the values come in from the network.
  Letting compile type incompatible compile errors (present when user
  namespaces are enabled) guide me to find the issues.

  The most tricky areas have been the places where we had an implicit
  union of uid and gid values and were storing them in an unsigned int.
  Those places were converted into explicit unions.  I made certain to
  handle those places with simple trivial patches.

  Out of that work I discovered we have generic interfaces for storing
  quota by projid.  I had never heard of the project identifiers before.
  Adding full user namespace support for project identifiers accounts
  for most of the code size growth in my git tree.

  Ultimately there will be work to relax privlige checks from
  "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing
  root in a user names to do those things that today we only forbid to
  non-root users because it will confuse suid root applications.

  While I was pushing kuid_t and kgid_t changes deep into the audit code
  I made a few other cleanups.  I capitalized on the fact we process
  netlink messages in the context of the message sender.  I removed
  usage of NETLINK_CRED, and started directly using current->tty.

  Some of these patches have also made it into maintainer trees, with no
  problems from identical code from different trees showing up in
  linux-next.

  After reading through all of this code I feel like I might be able to
  win a game of kernel trivial pursuit."

Without this patch and the patch to make include the UAPI headers from the core

because the DRM code relies on specific -I flags to make #include "..."  work

Linus Torvalds 033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

Previously read-only KMS ioctls had some somewhat inconsistent settings

did not require master, but GETPLANERESOURCES, GETPROPERTY, etc. did.

At least for debugging, it is nice to be able to use modetest to dump
property values while another process is master, and there seems to
be no harm in allowing read-only access to the KMS state to other

For drivers that can support rotated scanout, the extra parameter
checking in drm-core, while nice, tends to get confused.  To solve
this drivers can set the crtc or plane invert_dimensions field so
that the dimension checking takes into account the rotation that
the driver is performing.

    Userspace can give rotated src coordinates, so invert_dimensions
    is not required for planes.

Rob Clark f7eff60ea0 drm: refcnt drm_framebuffer (v4.1)
This simplifies drm fb lifetime, and if the crtc/plane needs to hold
a ref to the fb when disabling a pipe until the next vblank, this
avoids the need to make disabling an overlay synchronous.  This is a
problem that shows up when userspace is using a drm plane to
implement a hw cursor.. making overlay disable synchronous causes
a performance problem when x11 is rapidly enabling/disabling the
hw cursor.  But not making it synchronous opens up a race condition
for crashing if userspace turns around and immediately deletes the
fb.  Refcnt'ing the fb makes it possible to solve this problem.

v1: original
v2: add drm_framebuffer_remove() which is called in all paths where
    fb->funcs->destroy() was directly called before.  This cleans
    up the CRTCs/planes that the fb was attached to.  You should
    only directly use drm_framebuffer_unreference() if you are also
    using drm_framebuffer_reference() to keep a ref to the fb.
v3: add comment explaining the fb refcount

This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

Ben Hutchings says:

====================
Some bug fixes that should go into 3.7:

1. Fix oops when removing device with SR-IOV enabled.  (This regression
was introduced by the last set of changes, so the fix does not need to
be applied to any earlier kernel versions.)
2. Fix firmware structure field lookup bug that resulted in missing
sensor information.
3. Fix bug that makes self-test do very little in some configurations.
4. Fix the numbering of ethtool RX flow steering filters to reflect the
real hardware priorities.

Linus Torvalds ac9e7ab32f ARM: soc: cleanups, part 2
A shorter cleanup branch submitted separately due to dependencies with
 some of the previous topics.
 
 Major thing here is that the Broadcom bcmring platform is removed. It's an
 SoC that's used on some stationary VoIP platforms, and is in desperate
 need of some cleanup. Broadcom came back and suggested that we just
 deprecate the platform for now, since they aren't going to spend the
 resources needed on cleaning it up, and there are no users of the platform
 directly from mainline.

Linus Torvalds 11801e9de2 ARM: soc: soc-specific updates
Most notable here is probably the addition of basic support for the
 BCM2835, an SoC used in some of the Roku 2 players as well as the
 much-hyped Raspberry Pi, cleaned up and contributed by Stephen
 Warren. It's still early days on mainline support, with just the
 basics working. But it has to start somewhere!
 
 Beyond that there's some conversions of clock infrastructure on tegra
 to common clock, misc updates for several other platforms, and OMAP
 now has its own bus (under drivers/bus) to manage its devices through.
 
 This branch adds two new directories outside of arch/arm:
 drivers/irqchip for new irq controllers, and drivers/bus for the above
 OMAP bus. It's expected that some of the other platforms will migrate
 parts of their platforms to those directories over time as well.

This is a large branch that contains a handful of different cleanups:
 
 - Fixing up the I/O space remapping on PCI on ARM. This is a series
   from Rob Herring that restructures how all pci devices allocate I/O
   space, and it's part of the work to allow multiplatform kernels.
 - A number of cleanup series for OMAP, moving and removing some
   headers, sparse irq rework and in general preparation for
   multiplatform.
 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra

Ben Hutchings 6ac7ef1487 sfc: Fix the reported priorities of different filter types
Each RX filter table contains filters with two different levels of
specificity: TCP/IPv4 and UDP/IPv4 filters match the local address and
port and optionally the remote address and port; Ethernet filters
match the local address and optionally the VID.  The more specific
filters always override less specific filters within the same table,
and should be numbered accordingly.

Ben Hutchings 726ba0e14a sfc: Fix null function pointer in efx_sriov_channel_type
Commit c31e5f9 ('sfc: Add channel specific receive_skb handler and
post_remove callback') added the function pointer field
efx_channel_type::post_remove and an unconditional call through it.

This field should have been initialised to efx_channel_dummy_op_void
in the existing instances of efx_channel_type, but this was only done
in efx_default_channel_type.  Consequently, if a device has SR-IOV
enabled then removing the driver or device will result in an oops.

Paul Gortmaker de0a41484c tg3: unconditionally select HWMON support when tg3 is enabled.
There is the seldom used corner case where HWMON=m at the same
time as TIGON3=y (typically randconfigs) which will cause a link
fail like:

drivers/built-in.o: In function `tg3_close':
tg3.c:(.text+0x16bd86): undefined reference to `hwmon_device_unregister'
drivers/built-in.o: In function `tg3_hwmon_open':
tg3.c:(.text+0x16fc4b): undefined reference to `hwmon_device_register'
make[1]: *** [vmlinux] Error 1

Fix it as suggested by DaveM[1] by having the Kconfig logic simply
select HWMON when TIGON3 is selected.  This gets rid of all the
extra IS_ENABLED ifdeffery in tg3.c as a side benefit.

Wolfgang Grandegger 4f72e5f00d flexcan: disable bus error interrupts for the i.MX28
Due to a bug in most Flexcan cores, the bus error interrupt needs
to be enabled. Otherwise we don't get any error warning or passive
interrupts. This is _not_ necessary for the i.MX28 and this patch
disables bus error interrupts if "berr-reporting" is not requested.
This avoids bus error flooding, which might harm, especially on
low-end systems.

To handle such quirks of the Flexcan cores, a hardware feature flag
has been introduced, also replacing the "hw_ver" variable. So far
nobody could tell what Flexcan core version is available on what
Freescale SOC, apart from the i.MX6Q and P1010, and which bugs or
features are present on the various "hw_rev".

Yuval Mintz 96bed4b954 bnx2x,cnic: use FW 7.8.2
This patch moves the bnx2x and cnic drivers into using FW 7.8.2
which was recently submitted into the linux-firmware tree.

A short summary of minor bugs fixed by this FW:
 1. In switch dependent mode, fix several issues regarding inner vlan
    vs. DCB priorities.
 2. iSCSI - not all packets were completed on a forward channel.
 3. DCB - fixed for 4-port devices.
 4. Fixed false parity reported in CAM memories when operating near -5%
    on the 1.0V core supply.
 5. ETS default settings are set to fairness between traffic classes
    (rather than strict priority), and uses the same chip receive buffer
    configuration for both PFC and pause.

For a complete list of fixes made by this FW, see commit 236367db
in the linux-firmware git repository.

Linus Torvalds 3498d13b80 TTY merge for 3.7-rc1
As we skipped the merge window for 3.6-rc1 for the tty tree, everything
 is now settled down and working properly, so we are ready for 3.7-rc1.
 Here's the patchset, it's big, but the large changes are removing a
 firmware file and adding a staging tty driver (it depended on the tty
 core changes, so it's going through this tree instead of the staging
 tree.)

Linus Torvalds def7cb8cd4 Staging tree update for 3.7-rc1
Here is the big staging tree update for the 3.7-rc1 merge window.
 
 There are a few patches in here that are outside of the staging area,
 namely HID and IIO patches, but all of them have been acked by the
 relevant subsystem maintainers.  The IIO stuff is still coming in
 through this tree as it hasn't entirely moved out of the staging tree,
 but is almost there.
 
 Other than that, there wa a ton of work on the comedi drivers to make
 them more readable and the correct style.  Doing that removed a lot of
 code, but we added a new driver to the staging tree, so we didn't end up
 with a net reduction this time around:

Linus Torvalds 7e92daaefa Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf update from Ingo Molnar:
 "Lots of changes in this cycle as well, with hundreds of commits from
  over 30 contributors.  Most of the activity was on the tooling side.

  Higher level changes:

   - New 'perf kvm' analysis tool, from Xiao Guangrong.

   - New 'perf trace' system-wide tracing tool

   - uprobes fixes + cleanups from Oleg Nesterov.

   - Lots of patches to make perf build on Android out of box, from
     Irina Tirdea

   - Extend ftrace function tracing utility to be more dynamic for its
     users.  It allows for data passing to the callback functions, as
     well as reading regs as if a breakpoint were to trigger at function
     entry.

     The main goal of this patch series was to allow kprobes to use
     ftrace as an optimized probe point when a probe is placed on an
     ftrace nop.  With lots of help from Masami Hiramatsu, and going
     through lots of iterations, we finally came up with a good
     solution.

   - Add cpumask for uncore pmu, use it in 'stat', from Yan, Zheng.

   - Various tracing updates from Steve Rostedt

   - Clean up and improve 'perf sched' performance by elliminating lots
     of needless calls to libtraceevent.

   - Event group parsing support, from Jiri Olsa

   - UI/gtk refactorings and improvements from Namhyung Kim

   - Add support for non-tracepoint events in perf script python, from
     Feng Tang

   - Add --symbols to 'script', similar to the one in 'report', from
     Feng Tang.

  Infrastructure enhancements and fixes:

   - Convert the trace builtins to use the growing evsel/evlist
     tracepoint infrastructure, removing several open coded constructs
     like switch like series of strcmp to dispatch events, etc.
     Basically what had already been showcased in 'perf sched'.

   - Add evsel constructor for tracepoints, that uses libtraceevent just
     to parse the /format events file, use it in a new 'perf test' to
     make sure the libtraceevent format parsing regressions can be more
     readily caught.

   - Some strange errors were happening in some builds, but not on the
     next, reported by several people, problem was some parser related
     files, generated during the build, didn't had proper make deps, fix
     from Eric Sandeen.

   - Introduce struct and cache information about the environment where
     a perf.data file was captured, from Namhyung Kim.

   - Fix handling of unresolved samples when --symbols is used in
     'report', from Feng Tang.

   - Add union member access support to 'probe', from Hyeoncheol Lee.

   - Fixups to die() removal, from Namhyung Kim.

   - Render fixes for the TUI, from Namhyung Kim.

   - Don't enable annotation in non symbolic view, from Namhyung Kim.

   - Fix pipe mode in 'report', from Namhyung Kim.

   - Move related stats code from stat to util/, will be used by the
     'stat' kvm tool, from Xiao Guangrong.

   - Remove die()/exit() calls from several tools.

   - Resolve vdso callchains, from Jiri Olsa

   - Don't pass const char pointers to basename, so that we can
     unconditionally use libgen.h and thus avoid ifdef BIONIC lines,
     from David Ahern

   - Refactor hist formatting so that it can be reused with the GTK
     browser, From Namhyung Kim

   - Fix build for another rbtree.c change, from Adrian Hunter.

   - Make 'perf diff' command work with evsel hists, from Jiri Olsa.

   - Use the only field_sep var that is set up: symbol_conf.field_sep,
     fix from Jiri Olsa.

   - .gitignore compiled python binaries, from Namhyung Kim.

   - Get rid of die() in more libtraceevent places, from Namhyung Kim.

   - Rename libtraceevent 'private' struct member to 'priv' so that it
     works in C++, from Steven Rostedt

   - Remove lots of exit()/die() calls from tools so that the main perf
     exit routine can take place, from David Ahern

   - Fix x86 build on x86-64, from David Ahern.

   - {int,str,rb}list fixes from Suzuki K Poulose

   - perf.data header fixes from Namhyung Kim

   - Allow user to indicate objdump path, needed in cross environments,
     from Maciek Borzecki

   - Fix hardware cache event name generation, fix from Jiri Olsa

   - Add round trip test for sw, hw and cache event names, catching the
     problem Jiri fixed, after Jiri's patch, the test passes
     successfully.

   - Clean target should do clean for lib/traceevent too, fix from David
     Ahern

   - Check the right variable for allocation failure, fix from Namhyung
     Kim

   - Set up evsel->tp_format regardless of evsel->name being set
     already, fix from Namhyung Kim

   - Oprofile fixes from Robert Richter.

   - Remove perf_event_attr needless version inflation, from Jiri Olsa

   - Introduce libtraceevent strerror like error reporting facility,
     from Namhyung Kim

   - Add pmu mappings to perf.data header and use event names from cmd
     line, from Robert Richter

   - Fix include order for bison/flex-generated C files, from Ben
     Hutchings

   - Build fixes and documentation corrections from David Ahern

   - Assorted cleanups from Robert Richter

   - Let O= makes handle relative paths, from Steven Rostedt

   - perf script python fixes, from Feng Tang.

   - Initial bash completion support, from Frederic Weisbecker

   - Allow building without libelf, from Namhyung Kim.

   - Support DWARF CFI based unwind to have callchains when %bp based
     unwinding is not possible, from Jiri Olsa.

   - Symbol resolution fixes, while fixing support PPC64 files with an
     .opt ELF section was the end goal, several fixes for code that
     handles all architectures and cleanups are included, from Cody
     Schafer.

   - Assorted fixes for Documentation and build in 32 bit, from Robert
     Richter

   - Cache the libtraceevent event_format associated to each evsel
     early, so that we avoid relookups, i.e.  calling pevent_find_event
     repeatedly when processing tracepoint events.

     [ This is to reduce the surface contact with libtraceevents and
        make clear what is that the perf tools needs from that lib: so
        far parsing the common and per event fields.  ]

   - Don't stop the build if the audit libraries are not installed, fix
     from Namhyung Kim.

   - Fix bfd.h/libbfd detection with recent binutils, from Markus
     Trippelsdorf.

   - Improve warning message when libunwind devel packages not present,
     from Jiri Olsa"

Linus Torvalds 620e77533f Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU changes from Ingo Molnar:

 0. 'idle RCU':

     Adds RCU APIs that allow non-idle tasks to enter RCU idle mode and
     provides x86 code to make use of them, allowing RCU to treat
     user-mode execution as an extended quiescent state when the new
     RCU_USER_QS kernel configuration parameter is specified.  (Work is
     in progress to port this to a few other architectures, but is not
     part of this series.)

 1.  A fix for a latent bug that has been in RCU ever since the addition
     of CPU stall warnings.  This bug results in false-positive stall
     warnings, but thus far only on embedded systems with severely
     cut-down userspace configurations.

 2.  Further reductions in latency spikes for huge systems, along with
     additional boot-time adaptation to the actual hardware.

     This is a large change, as it moves RCU grace-period initialization
     and cleanup, along with quiescent-state forcing, from softirq to a
     kthread.  However, it appears to be in quite good shape (famous
     last words).

 3.  Updates to documentation and rcutorture, the latter category
     including keeping statistics on CPU-hotplug latencies and fixing
     some initialization-time races.

 4.  CPU-hotplug fixes and improvements.

 5.  Idle-loop fixes that were omitted on an earlier submission.

 6.  Miscellaneous fixes and improvements

In certain RCU configurations new kernel threads will show up (rcu_bh,
rcu_sched), showing RCU processing overhead.

* 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (90 commits)

Stephen Warren 536a53a300 spi: remove completely broken Tegra driver
The current SPI driver has many issues. Examples are:

* Segfaulting on most transfers due to expecting all transfers to have
  both RX and TX buffers.
* Hanging on TX transfers since the whole driver flow is driven by RX
  DMA completion, but the HW is only told to enable RX for RX transfers.
* Use of clk_disable_unprepare() from atomic context.
* Once those and other minor issues are fixed, the driver still doesn't
  actually work.
* The driver also implements a deprecated API to the SPI core.

For this reason, simply remove the driver completely. This has two
advantages:

1) This will remove the last use of Tegra's <mach/dma.h>, which will
   allow that file to be removed, which is required for single zImage
   work.

2) The downstream driver is significaly different from the current
   code. I believe a patch to re-add the downstream driver (with
   appropriate cleanup) will be much simpler to review if it's a new
   file rather than randomly interspered with essentially unrelated
   existing code.

Roland Dreier aadf4f3f66 mlx4_core: Disable SENSE_PORT for multifunction devices
In the current driver, the SENSE_PORT firmware command is issued as a
"wrapped" command, but the command handling code doesn't have a
wrapper, so it will never do anything other than log an error message.
The latest ConnectX-3 2.11.500 firmware reports the SENSE_PORT
capability even in multi-function (SR-IOV) mode, so the driver will
try to issue the command.

At least until the driver has a proper wrapper for SENSE_PORT, make
sure we disable the command for multi-function devices.

Kevin Daughtridge 86e6b77eb7 HID: keep dev_rdesc unmodified and use it for comparisons
The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.

usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

Simon Arlott e1b2dc70cd pinctrl: add bcm2835 driver
The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
controller, and pinmux/control device.

Original driver by Simon Arlott.
Rewrite including GPIO chip device by Chris Boot.

Upstreaming changes by Stephen Warren:
* Wrote DT binding documentation.
* Changed brcm,function to an integer to more directly match the
  datasheet, and to match brcm,pins being an integer.
* Implemented pull-up/down pin config.
* Removed read-only DT property and related code. The restriction this
  implemented are driven by the board, not the GPIO HW block, so don't
  really make sense of a HW block binding, were in general incomplete
  (since they could only know about the few pins hard-coded into the
  Raspberry Pi B board design and not the uncommitted GPIOS), and are
  better represented simply by not writing incorrect data into pin
  configuration nodes.
* Don't set GPIO_IN function select in gpio_request_enable() to avoid
  glitches; defer this to gpio_set_direction(). Consequently, removed
  empty bcm2835_pmx_gpio_request_enable().
* Simplified enabled_irq_map[]; make it explicitly 1 entry per bank.
* Lifted use of enabled_irq_map[] outside the per-interrupt loop in
  IRQ handler, thus fixing an issue where the code was indexing into
  enabled_irq_map[] by intra-bank GPIO ID, not global GPIO ID.
* Removed locking in IRQ handler, since all other code uses
  spin_lock_irqsave() and so guarantees it doesn't run concurrently
  with the handler.
* Moved duplicated BUILD_BUG_ON()s into probe(). Also check size of
  bcm2835_gpio_pins[].
* Remove range-checking from bcm2835_pctl_get_groups_count() since we've
  decided to trust the pinctrl core.
* Made bcm2835_pmx_gpio_disable_free() call bcm2835_pinctrl_fsel_set()
  directly for simplicity.
* Fixed body of dt_free_map() to match latest dt_node_to_map().
* Removed GPIO ownership check from bcm2835_pmx_enable() since the pinctrl
  core owns doing this.
* Made irq_chip and pinctrl_gpio_range .name == MODULE_NAME so it's more
  descriptive.
* Simplified remove(); removed call to non-existent
  pinctrl_remove_gpio_range(), remove early return on error.
* Don't force gpiochip's base to 0. Set gpio_range.base to gpiochip's
  base GPIO number.
* Error-handling cleanups in probe().
* Switched to module_platform_driver() rather than open-coding.
* Made pin, group, and function names lower-case.
* s/broadcom/brcm/ in DT property names.
* s/2708/2835/.
* Fixed a couple minor checkpatch warnings, and other minor cleanup.

Roland Dreier f3d4c89ee4 mlx4_core: Fix crash on uninitialized priv->cmd.slave_sem
On an SR-IOV master device, __mlx4_init_one() calls mlx4_init_hca()
before mlx4_multi_func_init().  However, for unlucky configurations,
mlx4_init_hca() might call mlx4_SENSE_PORT() (via mlx4_dev_cap()), and
that calls mlx4_cmd_imm() with MLX4_CMD_WRAPPED set.

However, on a multifunction device with MLX4_CMD_WRAPPED, __mlx4_cmd()
calls into mlx4_slave_cmd(), and that immediately tries to do

	down(&priv->cmd.slave_sem);

but priv->cmd.slave_sem isn't initialized until mlx4_multi_func_init()
(which we haven't called yet).  The next thing it tries to do is access
priv->mfunc.vhcr, but that hasn't been allocated yet.

Fix this by moving the initialization of slave_sem and vhcr up into
mlx4_cmd_init(). Also, since slave_sem is really just being used as a
mutex, convert it into a slave_cmd_mutex.

Jack Morgenstein 47605df953 mlx4: Modify proxy/tunnel QP mechanism so that guests do no calculations
Previously, the structure of a guest's proxy QPs followed the
structure of the PPF special qps (qp0 port 1, qp0 port 2, qp1 port 1,
qp1 port 2, ...).  The guest then did offset calculations on the
sqp_base qp number that the PPF passed to it in QUERY_FUNC_CAP().

This is now changed so that the guest does no offset calculations
regarding proxy or tunnel QPs to use.  This change frees the PPF from
needing to adhere to a specific order in allocating proxy and tunnel
QPs.

Now QUERY_FUNC_CAP provides each port individually with its proxy
qp0, proxy qp1, tunnel qp0, and tunnel qp1 QP numbers, and these are
used directly where required (with no offset calculations).

To accomplish this change, several fields were added to the phys_caps
structure for use by the PPF and by non-SR-IOV mode:

    base_sqpn -- in non-sriov mode, this was formerly sqp_start.
    base_proxy_sqpn -- the first physical proxy qp number -- used by PPF
    base_tunnel_sqpn -- the first physical tunnel qp number -- used by PPF.

The current code in the PPF still adheres to the previous layout of
sqps, proxy-sqps and tunnel-sqps.  However, the PPF can change this
layout without affecting VF or (paravirtualized) PF code.

view" presented to the SM).

Under the iov/<pci slot number> directories, the admin may map the
index numbers in the physical tables (as under iov/ports) to the
paravirtualized index numbers that guests see.

For example, if the administrator, for port 1 on guest 2 maps physical
pkey index 10 to virtual index 1, then that guest, whenever it uses
its pkey index 1, will actually be using the real pkey index 10.
