Pull powerpc fixes from Ben Herrenschmidt:
 "Here is a series of powerpc fixes.  It's a bit big, mostly because of
  the series of 11 "EEH" patches from Gavin.  The EEH (Our IBM specific
  PCI/PCIe Enhanced Error Handling) code had been rotting for a while
  and this merge window saw a significant rework & fixing of it by Gavin
  Shan.

  However, that wasn't complete and left some open issues.  There were
  still a few corner cases that didn't work properly, for example in
  relation to hotplug and devices without explicit error handlers.  We
  had some patches but they weren't quite good enough yet so I left them
  off the 3.11 merge window.

  Gavin since then fixed it all up, we ran quite a few rounds of testing
  and it seems fairly solid (at least probably more than it has ever
  been).  This should probably have made -rc1 but both Gavin and I took
  some vacation so it had to wait for -rc2.

  The rest is more bug fixes, mostly to new features recently added, for
  example, we missed the cpu table entry for one of the two models of P8
  (we didn't realize they had different PVR [Processor Version Register]
  values), some module CRC issues, etc..."

Completely ignore BHRB privilege state filter request as we are
already configuring that with privilege state filtering attribute
for the accompanying PMU event. This would help achieve cleaner
user space interaction for BHRB.

This patch fixes a situation like this

Before patch:-
------------
./perf record -j any -e branch-misses:k ls
Error:
The sys_perf_event_open() syscall returned with 95 (Operation not
supported) for event (branch-misses:k).
/bin/dmesg may provide additional information.
No CONFIG_PERF_EVENTS=y kernel support configured?

Here 'perf record' actually copies over ':k' filter request into BHRB
privilege state filter config and our previous check in kernel would
fail that.

After patch:-
-------------
./perf record -j any -e branch-misses:k ls

the pci_dev instance. So we have to store those information to
EEH device in advance.

When EEH error happens to one specific PE, some devices with drivers
supporting EEH won't except hotplug on the device. However, there
might have other deivces without driver, or with driver without EEH
support. For the case, we need do partial hotplug in order to make
sure that the PE becomes absolutely quite during reset. Otherise,
the PE reset might fail and leads to failure of error recovery.

The current code doesn't handle that 'mixed' case properly, it either
uses the error callbacks to the drivers, or tries hotplug, but doesn't
handle a PE (EEH domain) composed of a combination of the two.

The patch intends to support so-called "partial" hotplug for EEH:
Before we do reset, we stop and remove those PCI devices without
EEH sensitive driver. The corresponding EEH devices are not detached
from its PE, but with special flag. After the reset is done, those
EEH devices with the special flag will be scanned one by one.

When EEH error happens to one specific PE, the device drivers
of its attached EEH devices (PCI devices) are checked to see
the further action: reset with complete hotplug, or reset without
hotplug. However, that's not enough for those PCI devices whose
drivers can't support EEH, or those PCI devices without driver.
So we need do so-called "partial hotplug" on basis of PCI devices.
In the situation, part of PCI devices of the specific PE are
unplugged and plugged again after PE reset.

The patch changes pcibios_add_pci_devices() so that it can support
full hotplug and so-called "partial" hotplug based on device-tree
or real hardware. It's notable that pci_of_scan.c has been changed
for a bit in order to support the "partial" hotplug based on dev-tree.

Most of the generic code already supports that, we just need to
plumb it properly on our side.

When we do normal hotplug, the PE (shadow EEH structure) shouldn't be
kept around.

However, we need to keep it if the hotplug an artifial one caused by
EEH errors recovery.

Since we remove EEH device through the PCI hook pcibios_release_device(),
the flag "purge_pe" passed to various functions is meaningless. So the patch
removes the meaningless flag and introduce new flag "EEH_PE_KEEP"
to save the PE while doing hotplug during EEH error recovery.

Module CRCs are implemented as absolute symbols that get resolved by
a linker script. We build an intermediate .o that contains an
unresolved symbol for each CRC. genksysms parses this .o, calculates
the CRCs and writes a linker script that "resolves" the symbols to
the calculated CRC.

Unfortunately the ppc64 relocatable kernel sees these CRCs as symbols
that need relocating and relocates them at boot. Commit d4703aef
(module: handle ppc64 relocating kcrctabs when CONFIG_RELOCATABLE=y)
added a hook to reverse the bogus relocations. Part of this patch
created a symbol at 0x0:

# head -2 /proc/kallsyms
0000000000000000 T reloc_start
c000000000000000 T .__start

This reloc_start symbol is causing lots of confusion to perf. It
thinks reloc_start is a massive function that stretches from 0x0 to
0xc000000000000000 and we get various cryptic errors out of perf,
including:

problem incrementing symbol count, skipping event

This patch removes the  reloc_start linker script label and instead
defines it as PHYSICAL_START. We also need to wrap it with
CONFIG_PPC64 because the ppc32 kernel can set a non zero
PHYSICAL_START at compile time and we wouldn't want to subtract
it from the CRCs in that case.

What happens is that bus_register needs a statically allocated lock_key

embeds struct bus_type (the whole struct, not a pointer to it) and the
whole thing gets dynamically allocated.

Pull tracing fixes and cleanups from Steven Rostedt:
 "This contains fixes, optimizations and some clean ups

  Some of the fixes need to go back to 3.10.  They are minor, and deal
  mostly with incorrect ref counting in accessing event files.

  There was a couple of optimizations that should have perf perform a
  bit better when accessing trace events.

  And some various clean ups.  Some of the clean ups are necessary to
  help in a fix to a theoretical race between opening a event file and
  deleting that event"

Pull thermal management fixes from Zhang Rui:
 "These are fixes collected over the last week, they fixes several
  problems caused by the x86_pkg_temp_thermal introduced in 3.11-rc1.

  Specifics:

   - the x86_pkg_temp_thermal driver causes crash on systems with no
     package MSR support as there is a bug in the logic to check
     presence of DTHERM and PTS feature together.  Added a change so
     that when there is no PTS support, module doesn't get loaded.

   - fix krealloc() misuse in pkg_temp_thermal_device_add().

     If krealloc() returns NULL, it doesn't free the original.  Thus if
     we want to exit because of the krealloc() failure, we must make
     sure the original one is freed.

   - The error code path of the x86 package temperature thermal driver's
     initialization routine makes an unbalanced call to
     get_online_cpus(), which causes subsequent CPU offline operations,
     and consequently system suspend, to permanently block in
     cpu_hotplug_begin() on systems where get_core_online() returns an
     error code.

     Remove the extra get_online_cpus() to fix the problem"

Pull gpio fixes from Linus Walleij:
 "A first round of GPIO fixes for the v3.11 series:
   - OMAP device tree boot fix
   - Handle an error condition in the MSM driver

  The OMAP patches have been around since around the merge window, but
  since they first caused more breakage I let them boil in -next for a
  while.  These should be fine now"
