Geert Uytterhoeven ba6e8b8f02 sh: sh7757: switch RSPI clock to dev ID match
Switch the RSPI MSTP clock on SH7757 from a con ID match to a dev ID
match, so we can start looking it up using clk_get() with a NULL ID.

Bobby Bingham a3c195144e sh: don't pass saved userspace state to exception handlers
The compiler is permitted to generate code which overwrites the
parameters to a function.  If those parameters include the only saved
copy we have of userspace's registers, we're in trouble.

Bobby Bingham abafe5d9b0 sh: push extra copy of r0-r2 for syscall parameters
When invoking syscall handlers on sh32, the saved userspace registers
are at the top of the stack.  This seems to have been intentional, as it
is an easy way to pass r0, r1, ...  to the handler as parameters 5, 6,
...

It causes problems, however, because the compiler is allowed to generate
code for a function which clobbers that function's own parameters.  For
example, gcc generates the following code for clone:

    <SyS_clone>:
        mov.l   8c020714 <SyS_clone+0xc>,r1  ! 8c020540 <do_fork>
        mov.l   r7,@r15
        mov     r6,r7
        jmp     @r1
        mov     #0,r6
        nop
        .word 0x0540
        .word 0x8c02

The `mov.l r7,@r15` clobbers the saved value of r0 passed from
userspace.  For most system calls, this might not be a problem, because
we'll be overwriting r0 with the return value anyway.  But in the case
of clone, copy_thread will need the original value of r0 if the
CLONE_SETTLS flag was specified.

The first patch in this series fixes this issue for system calls by
pushing to the stack and extra copy of r0-r2 before invoking the
handler.  We discard this copy before restoring the userspace registers,
so it is not a problem if they are clobbered.

Exception handlers also receive the userspace register values in a
similar manner, and may hit the same problem.  The second patch removes
the do_fpu_error handler, which looks susceptible to this problem and
which, as far as I can tell, has not been used in some time.  The third
patch addresses other exception handlers.

This patch (of 3):

The userspace registers are stored at the top of the stack when the
syscall handler is invoked, which allows r0-r2 to act as parameters 5-7.
Parameters passed on the stack may be clobbered by the syscall handler.
The solution is to push an extra copy of the registers which might be
used as syscall parameters to the stack, so that the authoritative set
of saved register values does not get clobbered.

A few system call handlers are also updated to get the userspace
registers using current_pt_regs() instead of from the stack.

Pull kvm updates from Paolo Bonzini:
 "PPC and ARM do not have much going on this time.  Most of the cool

  ARM has some caching fixes and PPC has transactional memory support in
  guests.  MIPS has some fixes, with more probably coming in 3.16 as
  QEMU will soon get support for MIPS KVM.

  For x86 there are optimizations for debug registers, which trigger on
  some Windows games, and other important fixes for Windows guests.  We
  now expose to the guest Broadwell instruction set extensions and also
  Intel MPX.  There's also a fix/workaround for OS X guests, nested
  virtualization features (preemption timer), and a couple kvmclock
  refinements.

  For s390, the main news is asynchronous page faults, together with
  improvements to IRQs (floating irqs and adapter irqs) that speed up
  virtio devices"

 * Make struct device_node a kobject and remove legacy /proc/device-tree
 * ePAPR conformance fixes
 * Update in-kernel DTC copy to version v1.4.0
 * Preparation changes for dynamic device tree overlays
 * minor bug fixes and documentation changes
 
 The most significant change in this branch is the conversion of struct
 device_node to be a kobject that is exposed via sysfs and removal of the
 old /proc/device-tree code. This simplifies the device tree handling
 code and tightens up the lifecycle on device tree nodes.

 "This time around, the powerpc merges are going to be a little bit more
  complicated than usual.

  This is the main pull request with most of the work for this merge
  window.  I will describe it a bit more further down.

  There is some additional cpuidle driver work, however I haven't
  included it in this tree as it depends on some work in tip/timer-core
  which Thomas accidentally forgot to put in a topic branch.  Since I
  didn't want to carry all of that tip timer stuff in powerpc -next, I
  setup a separate branch on top of Thomas tree with just that cpuidle
  driver in it, and Stephen has been carrying that in next separately
  for a while now.  I'll send a separate pull request for it.

  Additionally, two new pieces in this tree add users for a sysfs API
  that Tejun and Greg have been deprecating in drivers-core-next.
  Thankfully Greg reverted the patch that removes the old API so this
  merge can happen cleanly, but once merged, I will send a patch
  adjusting our new code to the new API so that Greg can send you the
  removal patch.

  Now as for the content of this branch, we have a lot of perf work for
  power8 new counters including support for our new "nest" counters
  (also called 24x7) under pHyp (not natively yet).

  We have new functionality when running under the OPAL firmware
  (non-virtualized or KVM host), such as access to the firmware error
  logs and service processor dumps, system parameters and sensors, along
  with a hwmon driver for the latter.

  There's also a bunch of bug fixes accross the board, some LE fixes,
  and a nice set of selftests for validating our various types of copy
  loops.

  On the Freescale side, we see mostly new chip/board revisions, some
  clock updates, better support for machine checks and debug exceptions,

Pull x86 vdso changes from Peter Anvin:
 "This is the revamp of the 32-bit vdso and the associated cleanups.

  This adds timekeeping support to the 32-bit vdso that we already have
  in the 64-bit vdso.  Although 32-bit x86 is legacy, it is likely to
  remain in the embedded space for a very long time to come.

  This removes the traditional COMPAT_VDSO support; the configuration
  variable is reused for simply removing the 32-bit vdso, which will
  produce correct results but obviously suffer a performance penalty.
  Only one beta version of glibc was affected, but that version was
  unfortunately included in one OpenSUSE release.

  This is not the end of the vdso cleanups.  Stefani and Andy have
  agreed to continue work for the next kernel cycle; in fact Andy has
  already produced another set of cleanups that came too late for this
  cycle.

  An incidental, but arguably important, change is that this ensures
  that unused space in the VVAR page is properly zeroed.  It wasn't
  before, and would contain whatever garbage was left in memory by BIOS
  or the bootloader.  Since the VVAR page is accessible to user space
  this had the potential of information leaks"

Commit 2223f6f6ee "x86: Clean up dumpstack_64.c code" changed
the irq_stack processing a little from what it was before.
The irq_stack_end variable needed to be cleared after its first
use. By setting irq_stack to the per cpu irq_stack and passing
that to analyze_stack(), and then clearing it after it is processed,
we can get back the original behavior.

Commit 2223f6f6ee "x86: Clean up dumpstack_64.c code" moved the used
variable to a local within the loop, but the in_exception_stack()
depended on being non-volatile with the ability to change it.

By always re-initializing the "used" variable to zero, it would cause
the in_exception_stack() to return the same thing each time, and
cause the dump_stack loop to go into an infinite loop.

Linus Torvalds c70929147a sound updates for 3.15-rc1
There have been lots of changes in ALSA core, HD-audio and ASoC, also
 most of PCI drivers touched by conversions of printks.  All these
 resulted in a high volume and wide ranged patch sets in this release.
 Many changes are fairly trivial, but also lots of nice cleanups and
 refactors.  There are a few new drivers, most notably, the Intel
 Haswell and Baytrail ASoC driver.
 
 Core changes:
 - A bit modernization; embed the device struct into snd_card struct,
   so that it may be referred from the beginning.  A new snd_card_new()
   function is introduced for that, and all drivers have been
   converted.
 
 - Simplification in the device management code in ALSA core;
   now managed by a simple priority list instead
 
 - Converted many kernel messages to use the standard dev_err() & co;
   this would be the pretty visible difference, especially for
   HD-audio.
 
 HD-audio:
 - Conexant codecs use the auto-parser as default now;
   the old static code still remains in case of regressions.
   Some old quirks have been rewritten with the fixups for auto-parser.
 
 - C-Media codecs also use the auto-parser as default now, too.
 
 - A device struct is assigned to each HD-audio codec, and the formerly
   hwdep attributes are accessible over the codec sysfs, too.
   hwdep attributes still remain for compatibility.
 
 - Split the PCI-specific stuff for HD-audio controller into a separate
   module, ane make a helper module for the generic controller driver.
   This is a preliminary change for supporting Tegra HDMI controller in
   near future, which slipped from 3.15 merge.
 
 - Device-specific fixes: mute LED support for Lenovo Ideapad,
   mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
   Dell laptop headset quirks
 
 - Make the HD-audio codec response a bit more robust
 
 - A few improvements on Realtek ALC282 / 283 about the pop noises
 
 - A couple of Intel HDMI fixes
 
 ASoC:
 - Lots of cleanups for enumerations; refactored lots of error prone
   original codes to use more modern APIs
 
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle
 
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues
 
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues
 
 - DPCM support for Intel Haswell and Bay Trail platforms, lots of
   fixes
 
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
 
 - Fixes for the simple-card DAI format DT mess
 
 - DT support for a couple more devices.
 
 - Use of the tdm_slot mapping in a few drivers
 
 Others:
 - Support of reset_resume callback for improved S4 in USB-audio driver;
   the device with boot quirks have been little tested, which we need

Merge tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There have been lots of changes in ALSA core, HD-audio and ASoC, also
  most of PCI drivers touched by conversions of printks.  All these
  resulted in a high volume and wide ranged patch sets in this release.
  Many changes are fairly trivial, but also lots of nice cleanups and
  refactors.  There are a few new drivers, most notably, the Intel
  Haswell and Baytrail ASoC driver.

  Core changes:
   - A bit modernization; embed the device struct into snd_card struct,
     so that it may be referred from the beginning.  A new
     snd_card_new() function is introduced for that, and all drivers
     have been converted.

   - Simplification in the device management code in ALSA core; now
     managed by a simple priority list instead

   - Converted many kernel messages to use the standard dev_err() & co;
     this would be the pretty visible difference, especially for
     HD-audio.

  HD-audio:
   - Conexant codecs use the auto-parser as default now; the old static
     code still remains in case of regressions.  Some old quirks have
     been rewritten with the fixups for auto-parser.

   - C-Media codecs also use the auto-parser as default now, too.

   - A device struct is assigned to each HD-audio codec, and the
     formerly hwdep attributes are accessible over the codec sysfs, too.
     hwdep attributes still remain for compatibility.

   - Split the PCI-specific stuff for HD-audio controller into a
     separate module, ane make a helper module for the generic
     controller driver.  This is a preliminary change for supporting
     Tegra HDMI controller in near future, which slipped from 3.15
     merge.

   - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
     fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
     laptop headset quirks

   - Make the HD-audio codec response a bit more robust

   - A few improvements on Realtek ALC282 / 283 about the pop noises

   - A couple of Intel HDMI fixes

  ASoC:
   - Lots of cleanups for enumerations; refactored lots of error prone
     original codes to use more modern APIs

   - Elimination of the ASoC level wrappers for I2C and SPI moving us
     closer to converting to regmap completely and avoiding some
     randconfig hassle

   - Provide both manually and transparently locked DAPM APIs rather
     than a mix of the two fixing some concurrency issues

   - Start converting CODEC drivers to use separate bus interface
     drivers rather than having them all in one file helping avoid
     dependency issues

   - DPCM support for Intel Haswell and Bay Trail platforms, lots of
     fixes

   - Lots of work on improvements for simple-card, DaVinci and the
     Renesas rcar drivers.

   - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
     the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8

   - Fixes for the simple-card DAI format DT mess

   - DT support for a couple more devices.

   - Use of the tdm_slot mapping in a few drivers

  Others:
   - Support of reset_resume callback for improved S4 in USB-audio
     driver; the device with boot quirks have been little tested, which
     we need to watch out in this development cycle

   - Add PM support for ICE1712 driver (finally!); it's still pretty
     partial support, only for M-Audio devices"

Linus Torvalds 4dedde7c7a ACPI and power management updates for 3.15-rc1
- Device PM QoS support for latency tolerance constraints on systems with
    hardware interfaces allowing such constraints to be specified.  That is
    necessary to prevent hardware-driven power management from becoming
    overly aggressive on some systems and to prevent power management
    features leading to excessive latencies from being used in some cases.
 
  - Consolidation of the handling of ACPI hotplug notifications for device
    objects.  This causes all device hotplug notifications to go through
    the root notify handler (that was executed for all of them anyway
    before) that propagates them to individual subsystems, if necessary,
    by executing callbacks provided by those subsystems (those callbacks
    are associated with struct acpi_device objects during device
    enumeration).  As a result, the code in question becomes both smaller
    in size and more straightforward and all of those changes should not
    affect users.
 
  - ACPICA update, including fixes related to the handling of _PRT in cases
    when it is broken and the addition of "Windows 2013" to the list of
    supported "features" for _OSI (which is necessary to support systems
    that work incorrectly or don't even boot without it).  Changes from
    Bob Moore and Lv Zheng.

Merge tag 'pm+acpi-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the

 "The irq department proudly presents:

   - Another tree wide sweep of irq infrastructure abuse.  Clear winner
     of the trainwreck engineering contest was:
         #include "../../../kernel/irq/settings.h"

   - Tree wide update of irq_set_affinity() callbacks which miss a cpu
     online check when picking a single cpu out of the affinity mask.

   - Tree wide consolidation of interrupt statistics.

   - Updates to the threaded interrupt infrastructure to allow explicit
     wakeup of the interrupt thread and a variant of synchronize_irq()
     which synchronizes only the hard interrupt handler.  Both are
     needed to replace the homebrewn thread handling in the mmc/sdhci
     code.

   - New irq chip callbacks to allow proper support for GPIO based irqs.
     The GPIO based interrupts need to request/release GPIO resources
     from request/free_irq.

   - A few new ARM interrupt chips.  No revolutionary new hardware, just
     differently wreckaged variations of the scheme.

   - Small improvments, cleanups and updates all over the place"

Ard Biesheuvel 8ceee72808 crypto: ghash-clmulni-intel - use C implementation for setkey()
The GHASH setkey() function uses SSE registers but fails to call
kernel_fpu_begin()/kernel_fpu_end(). Instead of adding these calls, and
then having to deal with the restriction that they cannot be called from
interrupt context, move the setkey() implementation to the C domain.

Note that setkey() does not use any particular SSE features and is not
expected to become a performance bottleneck.

Linus Torvalds 01d5f3b598 Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo:
 "A lot of activities on libata side this time.

   - A lot of changes around ahci.  Various embedded platforms are
     implementing ahci controllers.  Some were built atop ahci_platform,
     others were doing their own things.  Hans made some structural
     changes to libahci and librarized ahci_platform so that ahci
     platform drivers can share more common code.  A couple platform
     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are
     scheduled to be removed).

   - Dan finishes the patchset to make libata PM operations
     asynchronous.  Combined with one patch being routed through scsi,
     this should speed resume measurably.

   - Various fixes and cleanups from Bartlomiej and others"
