Paul Bolle 45b02f8d94 memblock: kill "config MAX_ACTIVE_REGIONS"
The Kconfig symbol MAX_ACTIVE_REGIONS is unused. Commit
0ee332c145 ("memblock: Kill
early_node_map[]") removed the only place were it was actually used. But
it did not remove its Kconfig entries (for powerpc and sh).

Remove those two entries (and the entry for metag, that popped up in
v3.9-rc1).

Alexandre Courbot 7fd2bf3d32 Remove GENERIC_GPIO config option
GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.

Al Viro d9dda78bad procfs: new helper - PDE_DATA(inode)
The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry

Viresh Kumar b43a7ffbf3 cpufreq: Notify all policy->cpus in cpufreq_notify_transition()
policy->cpus contains all online cpus that have single shared clock line. And
their frequencies are always updated together.

Many SMP system's cpufreq drivers take care of this in individual drivers but
the best place for this code is in cpufreq core.

This patch modifies cpufreq_notify_transition() to notify frequency change for
all cpus in policy->cpus and hence updates all users of this API.

Sasha Levin b67bfe0d42 hlist: drop the node parameter from iterators
I'm not sure why, but the hlist for each entry iterators were conceived

        list_for_each_entry(pos, head, member)

The hlist ones were greedy and wanted an extra parameter:

        hlist_for_each_entry(tpos, pos, head, member)

Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.

Besides the semantic patch, there was some manual work required:

 - Fix up the actual hlist iterators in linux/list.h
 - Fix up the declaration of other iterators based on the hlist ones.
 - A very small amount of places were using the 'node' parameter, this
 was modified to use 'obj->member' instead.
 - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
 properly, so those had to be fixed up manually.

The semantic patch which is mostly the work of Peter Senna Tschudin is here:

  to inode.  Some bits of preparation to xattr method interface changes.

  Misc patches by various people sent this cycle *and* ocfs2 fixes from
  several cycles ago that should've been upstream right then.

  PS: the next vfs pile will be xattr stuff."

Pull signal handling cleanups from Al Viro:
 "This is the first pile; another one will come a bit later and will
  contain SYSCALL_DEFINE-related patches.

   - a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
     (fixing several potential problems with missing argument
     validation, while we are at it)

   - a lot of now-pointless wrappers killed

   - a couple of architectures (cris and hexagon) forgot to save
     altstack settings into sigframe, even though they used the
     (uninitialized) values in sigreturn; fixed.

Wen Congyang 24d335ca36 memory-hotplug: introduce new arch_remove_memory() for removing page table
For removing memory, we need to remove page tables.  But it depends on
architecture.  So the patch introduce arch_remove_memory() for removing
page table.  Now it only calls __remove_pages().

Note: __remove_pages() for some archtecuture is not implemented
      (I don't know how to implement it for s390).

Linus Torvalds 7ae1c76ee5 arm-soc: pin muxing for sh-mobile
This is another cleanup series, containing the move of the Renesas
 SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
 generic pinctrl subsystem, changing it over to the common interfaces in
 the process.
 
 Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
 we're merging this large branch of pinctrl conversion through arm-soc,
 even though it contains the corresponding conversions for arch/sh. Main
 reason for this is tight dependencies (that will now mostly be broken)
 between the arch/sh and mach-shmobile implementations.
 
 There will be more of this in 3.10 to do device-tree bindings, but this
 is the initial conversion.

Linus Torvalds 460dc1eecf Sound updates for 3.9-rc1
The biggest change in this update is the unification of HD-audio codec
 parsers.  Now the HD-audio codec is parsed in a generic parser code
 which is invoked by each HD-audio codec driver.  Some background
 information is found in David Henningsson's blog entry:
   http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/
 
 Other than that, some random updates/fixes like USB-audio and a bunch
 of small AoC updates as usual.
 
 Highlights:
 
 - Unification of HD-audio parser code (aka generic parser)
 
 - Support of new Intel HD-audio controller, new IDT codecs
 
 - Fixes for HD-audio HDMI audio hotplug
 
 - Haswell HDMI audio fixup
 
 - Support of Creative CA0132 DSP code
 
 - A few fixes of HDSP driver
 
 - USB-audio fix for Roland A-PRO, M-Audio FT C600
 
 - Support PM for aloop driver (and fixes Oops)
 
 - Compress API updates for gapless playback support
 
 For ASoC part:
 
 - Support for a wider range of hardware in the compressed stream code
 
 - The ability to mute capture streams as well as playback streams while
   inactive
 
 - DT support for AK4642, FSI, Samsung I2S and WM8962
 
 - AC'97 support for Tegra
 
 - New driver for max98090, replacing the stub which was there
 
 - A new driver from Dialog
 
 Note that due to dependencies, DTification of DMA support for Samsung
 platforms (used only by the and I2S driver and SPI) is merged here as
 well.

James Hogan f7c819c020 arch Kconfig: Remove references to IRQ_PER_CPU
The IRQ_PER_CPU Kconfig symbol was removed in the following commit:

Commit 6a58fb3bad ("genirq: Remove
CONFIG_IRQ_PER_CPU") merged in v2.6.39-rc1.

But IRQ_PER_CPU wasn't removed from any of the architecture Kconfig
files where it was defined or selected. It's completely unused so remove
the remaining references.

Olof Johansson 7e5fc77931 Merge branch 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/sh-pinmux
From Simon Horman. Based on agreement between me, Paul Mundt, Linus
Walleij and Simon, we're mergning this large branch of pinctrl conversion
through arm-soc, even though it contains the corresponding conversions
for arch/sh. Main reason for this is tight dependencies (that will now
mostly be broken) between the arch/sh and mach-shmobile implementations.

There will be more of this in 3.10 to do device-tree bindings, but this is
the initial conversion.

Kuninori Morimoto a4a2992c53 ASoC: simple-card: add asoc_simple_dai for initializing
Current simple-card driver calls asoc_simple_card_dai_init()
if platform had a asoc_simple_card_dai_init pointer.
And, this initialization function works only
when platform has an applicable initial value for each dai settings.
And basically, almost all sound card requires certain initialization.
This means that almost all platform has initialization settings,
and driver do nothing if it doesn't have settings.

And additionally, current simple-card supports sysclk settings but it was
only for codec.  In order to abolish deviation between cpu and codec,
and in order to simplify processing,
this patch adds asoc_simple_dai, and removed pointless
struct asoc_simple_dai_init_info which was trigger of
calling asoc_simple_card_dai_init().

Greg Kroah-Hartman b881bc469b ARCH: drivers remove __dev* attributes.
This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Linus Torvalds 787314c35f IOMMU Updates for Linux v3.8
A few new features this merge-window. The most important one is
 probably, that dma-debug now warns if a dma-handle is not checked with
 dma_mapping_error by the device driver. This requires minor changes to
 some architectures which make use of dma-debug. Most of these changes
 have the respective Acks by the Arch-Maintainers.
 Besides that there are updates to the AMD IOMMU driver for refactor the
 IOMMU-Groups support and to make sure it does not trigger a hardware
 erratum.
 The OMAP changes (for which I pulled in a branch from Tony Lindgren's
 tree) have a conflict in linux-next with the arm-soc tree. The conflict
 is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
 the arm-soc tree. It is safe to delete the file too so solve the
 conflict. Similar changes are done in the arm-soc tree in the common
 clock framework migration. A missing hunk from the patch in the IOMMU
 tree will be submitted as a seperate patch when the merge-window is
 closed.

Merge tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma

Pull Automatic NUMA Balancing bare-bones from Mel Gorman:
 "There are three implementations for NUMA balancing, this tree
  (balancenuma), numacore which has been developed in tip/master and
  autonuma which is in aa.git.

  In almost all respects balancenuma is the dumbest of the three because
  its main impact is on the VM side with no attempt to be smart about
  scheduling.  In the interest of getting the ball rolling, it would be
  desirable to see this much merged for 3.8 with the view to building
  scheduler smarts on top and adapting the VM where required for 3.9.

  The most recent set of comparisons available from different people are

    mel:    https://lkml.org/lkml/2012/12/9/108
    mingo:  https://lkml.org/lkml/2012/12/7/331
    tglx:   https://lkml.org/lkml/2012/12/10/437
    srikar: https://lkml.org/lkml/2012/12/10/397

  The results are a mixed bag.  In my own tests, balancenuma does
  reasonably well.  It's dumb as rocks and does not regress against
  mainline.  On the other hand, Ingo's tests shows that balancenuma is
  incapable of converging for this workloads driven by perf which is bad
  but is potentially explained by the lack of scheduler smarts.  Thomas'
  results show balancenuma improves on mainline but falls far short of
  numacore or autonuma.  Srikar's results indicate we all suffer on a
  large machine with imbalanced node sizes.

  My own testing showed that recent numacore results have improved
  dramatically, particularly in the last week but not universally.
  We've butted heads heavily on system CPU usage and high levels of
  migration even when it shows that overall performance is better.
  There are also cases where it regresses.  Of interest is that for
  specjbb in some configurations it will regress for lower numbers of
  warehouses and show gains for higher numbers which is not reported by
  the tool by default and sometimes missed in treports.  Recently I
  reported for numacore that the JVM was crashing with
  NullPointerExceptions but currently it's unclear what the source of
  this problem is.  Initially I thought it was in how numacore batch
  handles PTEs but I'm no longer think this is the case.  It's possible
  numacore is just able to trigger it due to higher rates of migration.

  These reports were quite late in the cycle so I/we would like to start
  with this tree as it contains much of the code we can agree on and has
  not changed significantly over the last 2-3 weeks."

However, this merge disables CONFIG_MOVABLE_NODE, which was totally

David Rientjes c2d23f919b mm, oom: remove statically defined arch functions of same name
out_of_memory() is a globally defined function to call the oom killer.
x86, sh, and powerpc all use a function of the same name within file scope
in their respective fault.c unnecessarily.  Inline the functions into the
pagefault handlers to clean the code up.

Linus Torvalds 9977d9b379 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal
Pull big execve/kernel_thread/fork unification series from Al Viro:
 "All architectures are converted to new model.  Quite a bit of that
  stuff is actually shared with architecture trees; in such cases it's
  literally shared branch pulled by both, not a cherry-pick.

  A lot of ugliness and black magic is gone (-3KLoC total in this one):

   - kernel_thread()/kernel_execve()/sys_execve() redesign.

     We don't do syscalls from kernel anymore for either kernel_thread()
     or kernel_execve():

     kernel_thread() is essentially clone(2) with callback run before we
     return to userland, the callbacks either never return or do
     successful do_execve() before returning.

     kernel_execve() is a wrapper for do_execve() - it doesn't need to
     do transition to user mode anymore.

     As a result kernel_thread() and kernel_execve() are
     arch-independent now - they live in kernel/fork.c and fs/exec.c
     resp.  sys_execve() is also in fs/exec.c and it's completely
     architecture-independent.

   - daemonize() is gone, along with its parts in fs/*.c

   - struct pt_regs * is no longer passed to do_fork/copy_process/
     copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.

   - sys_fork()/sys_vfork()/sys_clone() unified; some architectures
     still need wrappers (ones with callee-saved registers not saved in
     pt_regs on syscall entry), but the main part of those suckers is in
     kernel/fork.c now."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (113 commits)
  do_coredump(): get rid of pt_regs argument
  print_fatal_signal(): get rid of pt_regs argument

Pull perf updates from Ingo Molnar:
 "Lots of activity:

   211 files changed, 8328 insertions(+), 4116 deletions(-)

  most of it on the tooling side.

  Main changes:

   * ftrace enhancements and fixes from Steve Rostedt.

   * uprobes fixes, cleanups and preparation for the ARM port from Oleg
     Nesterov.

   * UAPI fixes, from David Howels - prepares the arch/x86 UAPI
     transition

   * Separate perf tests into multiple objects, one per test, from Jiri
     Olsa.

   * Make hardware event translations available in sysfs, from Jiri
     Olsa.

   * Fixes to /proc/pid/maps parsing, preparatory to supporting data
     maps, from Namhyung Kim

   * Implement ui_progress for GTK, from Namhyung Kim

   * Add framework for automated perf_event_attr tests, where tools with
     different command line options will be run from a 'perf test', via
     python glue, and the perf syscall will be intercepted to verify
     that the perf_event_attr fields set by the tool are those expected,
     from Jiri Olsa

   * Add a 'link' method for hists, so that we can have the leader with
     buckets for all the entries in all the hists.  This new method is
     now used in the default 'diff' output, making the sum of the
     'baseline' column be 100%, eliminating blind spots.

   * libtraceevent fixes for compiler warnings trying to make perf it
     build on some distros, like fedora 14, 32-bit, some of the warnings
     really pointed to real bugs.

   * Add a browser for 'perf script' and make it available from the
     report and annotate browsers.  It does filtering to find the
     scripts that handle events found in the perf.data file used.  From
     Feng Tang

   * perf inject changes to allow showing where a task sleeps, from
     Andrew Vagin.

   * Makefile improvements from Namhyung Kim.

   * Add --pre and --post command hooks in 'stat', from Peter Zijlstra.

   * Don't stop synthesizing threads when one vanishes, this is for the
     existing threads when we start a tool like trace.

   * Use sched:sched_stat_runtime to provide a thread summary, this
     produces the same output as the 'trace summary' subcommand of
     tglx's original "trace" tool.

   * Support interrupted syscalls in 'trace'

   * Add an event duration column and filter in 'trace'.

   * There are references to the man pages in some tools, so try to
     build Documentation when installing, warning the user if that is
     not possible, from Borislav Petkov.

   * Give user better message if precise is not supported, from David
     Ahern.

   * Try to find cross-built objdump path by using the session
     environment information in the perf.data file header, from Irina
     Tirdea, original patch and idea by Namhyung Kim.

   * Diplays more output on features check for make V=1, so that one can
     figure out what is happening by looking at gcc output, etc.  From
     Jiri Olsa.

   * Add on_exit implementation for systems without one, e.g.  Android,
     from Bernhard Rosenkraenzer.

   * Only process events for vcpus of interest, helps handling large
     number of events, from David Ahern.

   * Cross compilation fixes for Android, from Irina Tirdea.

   * Add documentation on compiling for Android, from Irina Tirdea.

   * perf diff improvements from Jiri Olsa.

   * Target (task/user/cpu/syswide) handling improvements, from Namhyung
     Kim.

   * Add support in 'trace' for tracing workload given by command line,
     from Namhyung Kim.

   * ... and much more."

Linus Torvalds 414a6750e5 USB patches for 3.8-rc1
Here's the big set of USB patches for 3.8-rc1.
 
 Lots of USB host driver cleanups in here, and a bit of a reorg of the
 EHCI driver to make it easier for the different EHCI platform drivers to
 all work together nicer, which was a reduction in overall code.  We also
 deleted some unused firmware files, and got rid of the very old
 file_storage usb gadget driver that had been broken for a long time.
 This means we ended up removing way more code than added, always a nice
 thing to see:

Linus Torvalds cff2f741b8 Driver core updates for 3.8-rc1

 but all of the patches included here have been ACKed by their various

 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.

Peter Zijlstra cbee9f88ec mm: numa: Add fault driven placement and migration
NOTE: This patch is based on "sched, numa, mm: Add fault driven
	placement and migration policy" but as it throws away all the policy
	to just leave a basic foundation I had to drop the signed-offs-by.

This patch creates a bare-bones method for setting PTEs pte_numa in the
context of the scheduler that when faulted later will be faulted onto the
node the CPU is running on.  In itself this does nothing useful but any
placement policy will fundamentally depend on receiving hints on placement
from fault context and doing something intelligent about it.

David Sharp 8cbd9cc625 tracing,x86: Add a TSC trace_clock
In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.

Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

v2:
Move arch-specific bits out of generic code.
v3:
Rename "x86-tsc", cleanups
v7:
Generic arch bits in Kbuild.

Jeff Layton 91a27b2a75 vfs: define struct filename and have getname() return it
getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.

For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.

This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.

Later, we'll add other information to the struct as it becomes
convenient.

Shaohua Li 45cac65b0f readahead: fault retry breaks mmap file read random detection
.fault now can retry.  The retry can break state machine of .fault.  In
filemap_fault, if page is miss, ra->mmap_miss is increased.  In the second
try, since the page is in page cache now, ra->mmap_miss is decreased.  And
these are done in one fault, so we can't detect random mmap file access.

Add a new flag to indicate .fault is tried once.  In the second try, skip
ra->mmap_miss decreasing.  The filemap_fault state machine is ok with it.

I only tested x86, didn't test other archs, but looks the change for other
archs is obvious, but who knows :)

Will Deacon 5d3a551c28 mm: hugetlb: add arch hook for clearing page flags before entering pool
The core page allocator ensures that page flags are zeroed when freeing
pages via free_pages_check.  A number of architectures (ARM, PPC, MIPS)
rely on this property to treat new pages as dirty with respect to the data
cache and perform the appropriate flushing before mapping the pages into
userspace.

This can lead to cache synchronisation problems when using hugepages,
since the allocator keeps its own pool of pages above the usual page
allocator and does not reset the page flags when freeing a page into the
pool.

This patch adds a new architecture hook, arch_clear_hugepage_flags, so
that architectures which rely on the page flags being in a particular
state for fresh allocations can adjust the flags accordingly when a page
is freed into the pool.

Jiri Kosina 16f3e95b32 cross-arch: don't corrupt personality flags upon exec()
Historically, the top three bytes of personality have been used for
things such as ADDR_NO_RANDOMIZE, which made sense only for specific
architectures.

We now however have a flag there that is general no matter the
architecture (UNAME26); generally we have to be careful to preserve the
personality flags across exec().

This patch tries to fix all architectures that forcefully overwrite
personality flags during exec() (ppc32 and s390 have been fixed recently
by commits f9783ec862 ("[S390] Do not clobber personality flags on
exec") and 59e4c3a2fe ("powerpc/32: Don't clobber personality flags on
exec") in a similar way already).

Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers

Pull preparatory patches for user API disintegration from David Howells:
 "The patches herein prepare for the extraction of the Userspace API
  bits from the various header files named in the Kbuild files.

  New subdirectories are created under either include/uapi/ or
  arch/x/include/uapi/ that correspond to the subdirectory containing
  that file under include/ or arch/x/include/.

  The new subdirs under the uapi/ directory are populated with Kbuild
  files that mostly do nothing at this time.  Further patches will
  disintegrate the headers in each original directory and fill in the
  Kbuild files as they do it.

  These patches also:

   (1) fix up #inclusions of "foo.h" rather than <foo.h>.

   (2) Remove some redundant #includes from the DRM code.

   (3) Make the kernel build infrastructure handle Kbuild files both in
       the old places and the new UAPI place that both specify headers
       to be exported.

   (4) Fix some kernel tools that #include kernel headers during their
       build.

  I have compile tested this with allyesconfig against x86_64,
  allmodconfig against i386 and a scattering of additional defconfigs of
  other arches.  Prepared for main script

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.

David Howells 786d35d45c Make most arch asm/module.h files use asm-generic/module.h
Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.

Also, use the generic definition mod_arch_specific where possible.

To this end, I've defined three new config bools:

 (*) HAVE_MOD_ARCH_SPECIFIC

     Arches define this if they don't want to use the empty generic
     mod_arch_specific struct.

 (*) MODULES_USE_ELF_RELA

     Arches define this if their modules can contain RELA records.  This causes
     the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
     defined by the arch rather than have the core emit an error message.

 (*) MODULES_USE_ELF_REL

     Arches define this if their modules can contain REL records.  This causes
     the Elf_Rel mapping to be emitted and allows apply_relocate() to be
     defined by the arch rather than have the core emit an error message.

Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.

Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

flush[_delayed]_work_sync() are now spurious.  Mark them deprecated
and convert all users to flush[_delayed]_work().

If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.

This patch doesn't make any functional difference.

Mike Frysinger 800fb3ddee sh: dma: fix request_irq usage
When calling request_irq with IRQF_SHARED, the dev cookie must be set
(i.e. non-NULL), otherwise the code rejects it immediately with -EINVAL.
So restore the logic here where we'd pass a pointer to the name as a
dummy unique val.

Otherwise, booting up on my LANDISK system would fail with:
	DMAC Address Error0 request_irq fail

On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

Guennadi Liakhovetski d4c191dfb9 sh: ecovec: switch MMC power control to regulators
Power on the CN11 and CN12 SD/MMC slots on ecovec is controlled by GPIOs,
which makes it possible to use the fixed voltage regulator driver to switch
card power on and off.

Geert Uytterhoeven 363737d664 mtd/uclinux: Use generic __bss_stop instead of _ebss
The standard (see BSS_SECTION() in <asm-generic/vmlinux.lds.h> and
<asm-generic/sections.h>) symbol for the end of BSS is __bss_stop.
This allows to remove all local declarations that have been added to
several architectures just to please CONFIG_MTD_UCLINUX.
