2e341ca686 Sound updates for 3.5-rc1 
This is the first big chunk for 3.5 merges of sound stuff.
 There are a few big changes in different areas.  First off, the
 streaming logic of USB-audio endpoints has been largely rewritten
 for the better support of "implicit feedback".  If anything about USB
 got broken, this change has to be checked.
 
 For HD-audio, the resume procedure was changed; instead of delaying
 the resume of the hardware until the first use, now waking up immediately
 at resume.  This is for buggy BIOS.
 
 For ASoC, dynamic PCM support and the improved support for digital links
 between off-SoC devices are major framework changes.
 
 Some highlights are below:
 
 * HD-audio
 - Avoid the accesses of invalid pin-control bits that may stall the codec
 - V-ref setup cleanups
 - Fix the races in power-saving code
 - Fix the races in codec cache hashes and connection lists
 - Split some common codes for BIOS auto-parser to hda_auto_parser.c
 - Changed the PM resume code to wake up immediately for buggy BIOS
 - Creative SoundCore3D support
 - Add Conexant CX20751/2/3/4 codec support
 
 * ASoC
 - Dynamic PCM support, allowing support for SoCs with internal routing
   through components with tight sequencing and formatting constraints
   within their internal paths or where there are multiple components
   connected with CPU managed DMA controllers inside the SoC.
 - Greatly improved support for direct digital links between off-SoC
   devices, providing a much simpler way of connecting things like digital
   basebands to CODECs.
 - Much more fine grained and robust locking, cleaning up some of the
   confusion that crept in with multi-component.
 - CPU support for nVidia Tegra 30 I2S and audio hub controllers and
   ST-Ericsson MSP I2S controolers
 - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas
   Instruments LM49453.
 - Some regmap changes needed by the Tegra I2S driver.
 - mc13783 audio support.
 
 * Misc
 - Rewrite with module_pci_driver()
 - Xonar DGX support for snd-oxygen
 - Improvement of packet handling in snd-firewire driver
 - New USB-endpoint streaming logic
 - Enhanced M-audio FTU quirks and relevant cleanups
 - Increment the support of OSS devices to 256
 - snd-aloop accuracy improvement
 
 There are a few more pending changes for 3.5, but they will be
 sent slightly later as partly depending on the changes of DRM.

Linus Torvalds
269af9a1a0 Merge branch 'x86-extable-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull exception table generation updates from Ingo Molnar:
 "The biggest change here is to allow the build-time sorting of the
  exception table, to speed up booting.  This is achieved by the
  architecture enabling BUILDTIME_EXTABLE_SORT.  This option is enabled
  for x86 and MIPS currently.

  On x86 a number of fixes and changes were needed to allow build-time
  sorting of the exception table, in particular a relocation invariant
  exception table format was needed.  This required the abstracting out
  of exception table protocol and the removal of 20 years of accumulated
  assumptions about the x86 exception table format.

  While at it, this tree also cleans up various other aspects of
  exception handling, such as early(er) exception handling for
  rdmsr_safe() et al.

  All in one, as the result of these changes the x86 exception code is
  now pretty nice and modern.  As an added bonus any regressions in this
  code will be early and violent crashes, so if you see any of those,
  you'll know whom to blame!"

Fix up trivial conflicts in arch/{mips,x86}/Kconfig files due to nearby
modifications of other core architecture options.

ab0cce560e Revert "sched, perf: Use a single callback into the scheduler" 
This reverts commit cb04ff9ac4 ("sched, perf: Use a single
callback into the scheduler").

Before this change was introduced, the process switch worked
like this (wrt. to perf event schedule):

     schedule (prev, next)
       - schedule out all perf events for prev
       - switch to next
       - schedule in all perf events for current (next)

After the commit, the process switch looks like:

     schedule (prev, next)
       - schedule out all perf events for prev
       - schedule in all perf events for (next)
       - switch to next

The problem is, that after we schedule perf events in, the pmu
is enabled and we can receive events even before we make the
switch to next - so "current" still being prev process (event
SAMPLE data are filled based on the value of the "current"
process).

Thats exactly what we see for test__PERF_RECORD test. We receive
SAMPLES with PID of the process that our tracee is scheduled
from.

Discussed with Peter Zijlstra:

 > Bah!, yeah I guess reverting is the right thing for now. Sad
 > though.
 >
 > So by having the two hooks we have a black-spot between them
 > where we receive no events at all, this black-spot covers the
 > hand-over of current and we thus don't receive the 'wrong'
 > events.
 >
 > I rather liked we could do away with both that black-spot and
 > clean up the code a little, but apparently people rely on it.

This set includes some minor fixes and improvements.
 The one large patch addresses the special "nodir" mode,
 which has been a long neglected proof of concept, but
 with these fixes seems to be quite usable.  It allows
 the resource master to be assigned statically instead of
 dynamically, which can improve performance if there is
 little locality and most resources are shared.

Pull scheduler changes from Ingo Molnar:
 "The biggest change is the cleanup/simplification of the load-balancer:
  instead of the current practice of architectures twiddling scheduler
  internal data structures and providing the scheduler domains in
  colorfully inconsistent ways, we now have generic scheduler code in
  kernel/sched/core.c:sched_init_numa() that looks at the architecture's
  node_distance() parameters and (while not fully trusting it) deducts a
  NUMA topology from it.

  This inevitably changes balancing behavior - hopefully for the better.

  There are various smaller optimizations, cleanups and fixlets as well"

 "Lots of changes:

   - (much) improved assembly annotation support in perf report, with

    - kernel support for AMD IBS PMU hardware features.  Notably 'perf
      record -e cycles:p' and 'perf top -e cycles:p' should work without
      skid now, like PEBS does on the Intel side, because it takes
      advantage of IBS transparently.

    - the libtracevents library: it is the first step towards unifying
      tracing tooling and perf, and it also gives a tracing library for
      external tools like powertop to rely on.

    - infrastructure: various improvements and refactoring of the UI

    - infrastructure: cleanup and simplification of the profiling
      targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)

    - various ftrace updates: speedups, cleanups, robustness
      improvements.

    - typing 'make' in tools/ will now give you a menu of projects to

 Loads of changes here, and we just narrowly added more lines than we
 added:
  622 files changed, 28356 insertions(+), 26059 deletions(-)
 
 But, good news is that there is a number of subsystems that moved out of
 the staging tree, to their respective "real" portions of the kernel.
 
 Code that moved out was:
 	- iio core code
 	- mei driver
 	- vme core and bridge drivers
 
 There was one broken network driver that moved into staging as a step
 before it is removed from the tree (pc300), and there was a few new
 drivers added to the tree:
 	- new iio drivers
 	- gdm72xx wimax USB driver
 	- ipack subsystem and 2 drivers
 
 All of the movements around have acks from the various subsystem
 maintainers, and all of this has been in the linux-next tree for a

a481991467 USB 3.5-rc1 pull request 
Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
 
 It's touches a lot of different parts of the kernel, all USB drivers,
 due to some API cleanups (getting rid of the ancient err() macro) and
 some changes that are needed for USB 3.0 power management updates.
 
 There are also lots of new drivers, pimarily gadget, but others as well.
 We deleted a staging driver, which was nice, and finally dropped the
 obsolete usbfs code, which will make Al happy to never have to touch
 that again.
 
 There were some build errors in the tree that linux-next found a few
 days ago, but those were fixed by the most recent changes (all were due
 to us not building with CONFIG_PM disabled.)

Merge tag 'usb-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB 3.5-rc1 changes from Greg Kroah-Hartman:
 "Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.

  It's touches a lot of different parts of the kernel, all USB drivers,
  due to some API cleanups (getting rid of the ancient err() macro) and
  some changes that are needed for USB 3.0 power management updates.

  There are also lots of new drivers, pimarily gadget, but others as
  well.  We deleted a staging driver, which was nice, and finally
  dropped the obsolete usbfs code, which will make Al happy to never
  have to touch that again.

  There were some build errors in the tree that linux-next found a few
  days ago, but those were fixed by the most recent changes (all were
  due to us not building with CONFIG_PM disabled.)

f6a26ae769 arm-soc: board specific changes 
While we generally attempt to get rid of board specific files and replace
 them with device tree based descriptions, a lot of platforms have not
 come that far:
 
 In shmobile, we add two new board files because their recently started
 effort to add DT support has not proceeded enough to use it for all of
 the important hardware.
 
 In Kirkwood, we are adding support for new boards with a combination of
 DT and board file contents in multiple cases.
 
 pxa/mmp and imx are extending support for existing board files but not
 adding new ones.

a8159414d7 epoll: Fix user space breakage related to EPOLLWAKEUP 
Commit 4d7e30d (epoll: Add a flag, EPOLLWAKEUP, to prevent
suspend while epoll events are ready) caused some applications to
malfunction, because they set the bit corresponding to the new
EPOLLWAKEUP flag in their eventpoll flags and they don't have the
new CAP_EPOLLWAKEUP capability.

To prevent that from happening, change epoll_ctl() to clear
EPOLLWAKEUP in epds.events if the caller doesn't have the
CAP_EPOLLWAKEUP capability instead of failing and returning an
error code, which allows the affected applications to function
normally.

813a95e5b4 arm-soc: soc-specific pinctrl changes 
With this, five platforms are moving to the relatively new pinctrl
 subsystem for their pin management, replacing the older soc specific
 in-kernel interfaces with common code.
 
 There is quite a bit of net addition of code for each platform being
 added to the pinctrl subsystem. but the payback comes later when adding
 new boards can be done by only providing new device trees instead.
