"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

This patch fixes a situation like this
Before patch:-
------------

Error:
The sys_perf_event_open() syscall returned with 95 (Operation not
supported) for event (branch-misses:k).

powerpc/eeh: Use partial hotplug for EEH unaware drivers
When EEH error happens to one specific PE, some devices with drivers

might have other deivces without driver, or with driver without EEH
support. For the case, we need do partial hotplug in order to make

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

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

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

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

powerpc/modules: Module CRC relocation fix causes perf issues
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.

whole thing gets dynamically allocated.

Fix __wait_on_atomic_t() to call the action func if the counter != 0
Fix __wait_on_atomic_t() so that it calls the action func if the counter != 0
rather than if the counter is 0 so as to be analogous to __wait_on_bit().
Thanks to Yacine who found this by visual inspection.
This will affect FS-Cache in that it will could fail to sleep correctly when
trying to clean up after a netfs cookie is withdrawn.

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"
