We allow PMU driver to change the cpu on which the event
should be installed to. This happened in patch:

  e2d37cd2 ("perf: Allow the PMU driver to choose the CPU on which to install events")

This patch also forces all the group members to follow
the currently opened events cpu if the group happened
to be moved.

This and the change of event->cpu in perf_install_in_context()
function introduced in:

  0cda4c02 ("perf: Introduce perf_pmu_migrate_context()")

forces group members to change their event->cpu,
if the currently-opened-event's PMU changed the cpu
and there is a group move.

Above behaviour causes problem for breakpoint events,
which uses event->cpu to touch cpu specific data for
breakpoints accounting. By changing event->cpu, some
breakpoints slots were wrongly accounted for given
cpu.

Vinces's perf fuzzer hit this issue and caused following
WARN on my setup:

   WARNING: CPU: 0 PID: 20214 at arch/x86/kernel/hw_breakpoint.c:119 arch_install_hw_breakpoint+0x142/0x150()
   Can't find any breakpoint slot
   [...]

This patch changes the group moving code to keep the event's
original cpu.

The uncore_collect_events functions assumes that event group
might contain only uncore events which is wrong, because it
might contain any type of events.

This bug leads to uncore framework touching 'not' uncore events,
which could end up all sorts of bugs.

One was triggered by Vince's perf fuzzer, when the uncore code
touched breakpoint event private event space as if it was uncore
event and caused BUG:

   BUG: unable to handle kernel paging request at ffffffff82822068
   IP: [<ffffffff81020338>] uncore_assign_events+0x188/0x250
   ...

The code in uncore_assign_events() function was looking for
event->hw.idx data while the event was initialized as a
breakpoint with different members in event->hw union.

This patch forces uncore_collect_events() to collect only uncore
events.

  perf session: Do not fail on processing out of order event
  x86/asm/traps: Disable tracing and kprobes in fixup_bad_iret and sync_regs

Pull perf events update from Ingo Molnar:
 "On the kernel side there's few changes, the one that stands out is
  PEBS machine state sampling support on x86, by Stephane Eranian.

  On the tooling side:

  User visible tooling changes:

   - Don't open the DWARF info multiple times, keeping instead a dwfl
     handle in struct dso, greatly speeding up 'perf report' on powerpc.
     (Sukadev Bhattiprolu)

   - Introduce PARSE_OPT_DISABLED option flag and use it to avoid
     showing undersired options in tools that provides frontends to
     'perf record', like sched, kvm, etc (Namhyung Kim)

   - Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo
     Carvalho de Melo)

   - Fix annotation with kcore (Adrian Hunter)

   - Support source line numbers in annotate using a hotkey (Andi Kleen)

   - Callchain improvements including:
     * Enable printing the srcline in the history
     * Make get_srcline fall back to sym+offset (Andi Kleen)

   - TUI hist_entry browser fixes, including showing missing overhead
     value for first level callchain.  Detected comparing the output of
     --stdio/--gui (that matched) with --tui, that had this problem.
     (Namhyung Kim)

   - Support handling complete branch stacks as histograms (Andi Kleen)

  Tooling infrastructure changes:

   - Prep work for supporting per-pkg and snapshot counters in 'perf
     stat' (Jiri Olsa)

   - 'perf stat' refactorings, moving stuff from it to evsel.c to use in
     per-pkg/snapshot format changes (Jiri Olsa)

   - Add per-pkg format file parsing (Matt Fleming)

   - Clean up libelf feature support code (Namhyung Kim)

   - Add gzip decompression support for kernel modules (Namhyung Kim)

   - More prep patches for Intel PT, including a a thread stack and more
     stuff made available via the database export mechanism (Adrian
     Hunter)

   - More Intel PT work, including a facility to export sample data
     (comms, threads, symbol names, etc) in a database friendly way,
     with an script to use this to create a postgresql database.
     (Adrian Hunter)

   - Make sure that thread->mg->machine points to the machine where the
     thread exists (it was being set only for the kmaps kernel modules
     case, do it as well for the mmaps) and use it to shorten function
     signatures (Arnaldo Carvalho de Melo)

  ... and lots of other fixes and smaller improvements"

Pull asm-generic asm/io.h rewrite from Arnd Bergmann:
 "While there normally is no reason to have a pull request for
  asm-generic but have all changes get merged through whichever tree
  needs them, I do have a series for 3.19.

  There are two sets of patches that change significant portions of
  asm/io.h, and this branch contains both in order to resolve the
  conflicts:

   - Will Deacon has done a set of patches to ensure that all
     architectures define {read,write}{b,w,l,q}_relaxed() functions or
     get them by including asm-generic/io.h.

     These functions are commonly used on ARM specific drivers to avoid
     expensive L2 cache synchronization implied by the normal
     {read,write}{b,w,l,q}, but we need to define them on all
     architectures in order to share the drivers across architectures
     and to enable CONFIG_COMPILE_TEST configurations for them

   - Thierry Reding has done an unrelated set of patches that extends
     the asm-generic/io.h file to the degree necessary to make it useful
     on ARM64 and potentially other architectures"

Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann:
 "The GPMC driver has traditionally been considered a part of the OMAP
  platform code and tightly interweaved with some of the boards.

  With this cleanup, it has finally come to the point where it makes
  sense to move it out of arch/arm into drivers/memory, where we already
  have other drivers for similar hardware.  The cleanups are still
  ongoing, with the goal of eventually having a standalone driver that
  does not require an interface to architecture code.

  This is a separate branch because of dependencies on multiple other

  cleanups"

  support.  The branch is the largest one and contains 513 out of the
  total 972 non-merge arm-soc changesets for 3.19.

Pull ARM SoC cleanups from Arnd Bergmann:
 "The remaining cleanups for 3.19 are to a large part result of
  devicetree conversion nearing completion on two other platforms
  besides AT91:

   - Like AT91, Renesas shmobile is in the process to migrate to DT and
     multiplatform, but using a different approach of doing it one SoC
     at a time.  For 3.19, the r8a7791 platform and associated "Koelsch"
     board are considered complete and we remove the non-DT
     non-multiplatform support for this.

   - The ARM Versatile Express has supported DT and multiplatform for a
     long time, but we have still kept the legacy board files around,
     because not all drivers were fully working before.  We have finally
     taken the last step to remove the board files.

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
 "On Atmel AT91, the conversion to device tree is now considered
  complete, and all machines that were not already converted in 3.18 are
  assumed to be unused and dropped by the maintainer.

  All remaining board files that were written in C are dropped, and the
  ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
  altogether.  Cleaning up the last pieces was great fun, so I took the
  time to do some of the coding myself and removed several hundred code
  lines that ended up unused after the board files were done.

  There are still a couple of AT91 specific device drivers that are not
  converted to DT (CF, USB-OTG) and currently not working, and the
  platform itself is not "multiplatform"-enabled, but both issues are
  going to be taken care of in the 3.20 cycle.

  This is split out from the other cleanups purely based on the size of
  the branch"

Pull device mapper updates from Mike Snitzer:

 - Significant DM thin-provisioning performance improvements to meet
   performance requirements that were requested by the Gluster
   distributed filesystem.

   Specifically, dm-thinp now takes care to aggregate IO that will be
   issued to the same thinp block before issuing IO to the underlying
   devices.  This really helps improve performance on HW RAID6 devices
   that have a writeback cache because it avoids RMW in the HW RAID
   controller.

 - Some stable fixes: fix leak in DM bufio if integrity profiles were
   enabled, use memzero_explicit in DM crypt to avoid any potential for
   information leak, and a DM cache fix to properly mark a cache block
   dirty if it was promoted to the cache via the overwrite optimization.

 - A few simple DM persistent data library fixes

 - DM cache multiqueue policy block promotion improvements.

 - DM cache discard improvements that take advantage of range
   (multiblock) discard support in the DM bio-prison.  This allows for
   much more efficient bulk discard processing (e.g.  when mkfs.xfs
   discards the entire device).

 - Some small optimizations in DM core and RCU deference cleanups

 - DM core changes to suspend/resume code to introduce the new internal
   suspend/resume interface that the DM thin-pool target now uses to
   suspend/resume active thin devices when the thin-pool must
   suspend/resume.

   This avoids forcing userspace to track all active thin volumes in a
   thin-pool when the thin-pool is suspended for the purposes of
   metadata or data space resize.

Pull regulator updates from Mark Brown:
 "The main thing this time around is support for suspend mode
  configuration from DT which will enable some very useful power savings
  on systems where we can't rely on the bootloader configuration.  We
  still don't really support dynamic configuration of this at runtime,
  that may come later if there is any demand.

  Summary:
   - Support for specifying the target regulation mode and voltage
     during system suspend via DT, enabling power savings in that mode.
   - Reduce the default verbosity of the logging on boot, improving boot
     times especially for systems with very large numbers of regulators.
   - Lots of cleanups and fixes for Maxim PMIC drivers.

arch_spin_unlock_wait() looks very suboptimal, to the point I
think this is just wrong and can lead to livelock: if the lock
is heavily contended we can never see head == tail.

But we do not need to wait for arch_spin_is_locked() == F. If it
is locked we only need to wait until the current owner drops
this lock. So we could simply spin until old_head !=
lock->tickets.head in this case, but .head can overflow and thus
we can't check "unlocked" only once before the main loop.

Also, the "unlocked" check can ignore TICKET_SLOWPATH_FLAG bit.

Instead of having a local hack taking care of sending the tuning
command and as well to verify the response pattern, let's convert to
the common mmc_send_tuning() API instead.

Instead of having a local function taking care of sending the tuning
command, let's use the common mmc_send_tuning() API provided by the mmc
core. In this way the request will be handled as any other request by
sdhci core.

As an effect of this change, the pm_runtime_get_sync() call at
esdhc_prepare_tuning() isn't needed any more.

This patch will also introduce another change in behavior, since before
the response pattern to the tuning command wasn't verified by
sdhci-esdhc-imx. The mmc_send_tuning() does that.

To be able to use mmc_send_tuning() prior the struct mmc_card has been
allocated, let's convert it to take the struct mmc_host* as parameter
instead.
