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..."* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (23 commits)

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

While restoring BARs for one specific PCI device, the pci_dev
instance should have been released. So it's not reliable to use
the pci_dev instance on restoring BARs. However, we still need
some information (e.g. PCIe capability position, header type) from
the pci_dev instance. So we have to store those information to
EEH device in advance.Signed-off-by: Gavin Shan

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.Signed-off-by: Gavin Shan
Signed-off-by: Benjamin Herrenschmidt -
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.Signed-off-by: Gavin Shan

Currently, we're trasversing the EEH devices list using list_for_each_entry().
That's not safe enough because the EEH devices might be removed from
its parent PE while doing iteration. The patch replaces that with
list_for_each_entry_safe().Signed-off-by: Gavin Shan
Signed-off-by: Benjamin Herrenschmidt -
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.Signed-off-by: Gavin Shan
