When passing through PE to guest, that's possibly in frozen
state. The driver for the pass-through devices on guest side
can't be loaded successfully as reported. We already had one
gate in eeh_dev_open() to clear PE frozen state accordingly,
but that's not enough because the function is only called at
QEMU startup for once.
The patch adds another gate in eeh_pe_set_option() so that the
PE frozen state can be cleared at QEMU restart time.

The function eeh_pci_enable() is called to apply various requests
to one particular PE: Enabling EEH, Disabling EEH, Enabling IO,
Enabling DMA, Freezing PE. When enabling IO or DMA on one specific
PE, we need check that IO or DMA isn't enabled previously. But
the condition used to do the check isn't completely correct because
one PE would be in DMA frozen state with workable IO path, or vice
versa.
The patch fixes the improper condition.

The problem was reported by Carol: In the scenario of passing mlx4
adapter to guest, EEH error could be recovered successfully. When
returning the device back to host, the driver (mlx4_core.ko)
couldn't be loaded successfully because of error number -5 (-EIO)
returned from mlx4_get_ownership(), which hits offlined PCI device.
The root cause is that we missed to put the affected devices into
normal state on clearing PE isolated state right after PE reset.
The patch fixes above issue by putting the affected devices to
normal state when clearing PE isolated state in eeh_pe_state_clear().

The frozen state on one specific PE is probably caused by error
injection, which is done with help of PAPR error injection registers.
According to the hardware spec, those registers should be cleared
automatically after one-shot frozen PE. However, that's not always
true, at least on P7IOC of Firebird-L. So we have to clear them
before doing PE reset to avoid recursive EEH errors at recovery
stage.

err_injct), which accepts following formated string, to support
error injection. It will be used to support userland utility

When passing through device, its PE might have been put into frozen
state. One obvious example would be: the passed PE is forced to be
offline because of hitting maximal allowed EEH errors in userland.
In that case, the frozen state won't be cleared and then the PE is
returned back to host, which might not have chance detecting and
recovering from it.
The patch adds more check when passing through device and clear the
PE frozen state if necessary.

The PCI devices that have been passed through are enabled before
reset, we need restore to the enabled state after reset. Otherwise,
MMIO access might be issued to disabled devices after reset and

The patch adds one more option (EEH_OPT_FREEZE_PE) to set_option()
method to proactively freeze PE, which will be issued before resetting
pass-throughed PE to drop MMIO access during reset because it's

The patch adds sysfs entry "eeh_pe_state". Reading on it returns
the PE's state while writing to it clears the frozen state. It's
used to check or clear the PE frozen state from userland for

The patch also replaces printk(KERN_WARNING ...) with pr_warn() in
eeh_sysfs.c

eeh_check_failure() is used to check frozen state of the PE which
owns the indicated I/O address. The argument "val" of the function
isn't used. The patch drops it and return the frozen state of the

Enable on DCACHE_WORD_ACCESS on ppc64le. It should work on
ppc64 and ppc32 but we need to do some testing first.
A somewhat reasonable testcase used to show the performance
improvement - a repeated stat of a 33 byte filename that
doesn't exist:
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#define ITERATIONS 10000000
#define PATH "123456781234567812345678123456781"
int main(void)
{
unsigned long i;
struct stat buf;
for (i = 0; i < ITERATIONS; i++)
stat(PATH, &buf);
return 0;
}
runs 27% faster on POWER8.

On some platforms with no power management capabilities, the hotplug
implementation is allowed to return from a smp_ops.cpu_die() call as a
function return. Upon a CPU onlining event, the KVM CPU notifier tries
to reinstall the hyp stub, which fails on platform where no reset took
place following a hotplug event, with the message:
CPU1: smp_ops.cpu_die() returned, trying to resuscitate
CPU1: Booted secondary processor
Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x80409540
unexpected data abort in Hyp mode at: 0x80401fe8
unexpected HVC/SVC trap in Hyp mode at: 0x805c6170
since KVM code is trying to reinstall the stub on a system where it is
already configured.
To prevent this issue, this patch adds a check in the KVM hotplug
notifier that detects if the HYP stub really needs re-installing when a
CPU is onlined and skips the installation call if the stub is already in
place, which means that the CPU has not been reset.

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

Pull ARM SoC fixes from Olof Johansson:
"Here's our last set of fixes for 3.17. Most of these are for TI
platforms, fixing some noisy Kconfig issues, runtime clock and power
issues on several platforms and NAND timings on DRA7.
There are also a couple of bug fixes for i.MX, one for QCOM and a
small fix to avoid section mismatch noise on PXA.
Diffstat looks large, partially due to some tables being updated and
thus touching many lines. The qcom gsbi change also restructures
clock management a bit and thus touches a bunch of lines.
All in all, a bit more changes than we'd like at this point, but
nothing stands out as risky either so it seems like the right thing to
send it up now instead of holding it to the merge window"

"This has:
- EFI revert to fix a boot regression
- early_ioremap() fix for boot failure
- KASLR fix for possible boot failures
- EFI fix for corrupted string printing
- remove a misleading EFI bootup 'failed!' error message
Unfortunately it's all rather close to the merge window"

Allwinner Clocks Additions for 3.18
The most important part of this serie is the addition of the phase API to
handle the MMC clocks in the Allwinner SoCs.
Apart from that, the A23 gained a new mbus driver, and there's a fix for a
incorrect divider table on the APB0 clock.

In light of recent SNAFU with SMP build, allow simple platform to build
as SMP but run UP.
* Remove the dependence on simulation SMP extension to enable quick
build/test iterations of SMP kernel.
* In absence of platform SMP registration, prevent the NULL smp feature
name from borkign the system

This includes a bunch of changes:
- Support read-only memory slots on arm/arm64
- Various changes to fix Sparse warnings
- Correctly detect write vs. read Stage-2 faults
- Various VGIC cleanups and fixes
- Dynamic VGIC data strcuture sizing

- Fix VTTBR_BADDR Mask
- Correctly report the FSC on Stage-2 faults
Conflicts:
virt/kvm/eventfd.c
[duplicate, different patch where the kvm-arm version broke x86.
The kvm tree instead has the right one]

We changed PAGE_OFFSET to be a variable rather than a constant,
but this reference here in the hibernate assembler got missed.

John W. Linville says:
====================
pull request: wireless-next 2014-09-22
Please pull this batch of updates intended for the 3.18 stream...
For the mac80211 bits, Johannes says:
"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."
For the bluetooth bits, Johan says:
"Here are some more patches intended for 3.18. Most of them are cleanups
or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed
channels which should now work better together with the L2CAP
information request procedure."
For the iwlwifi bits, Emmanuel says:
"I fix here dvm which was broken by my last pull request. Arik
continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal
keeps digging into rate scaling code, more to come soon. Besides this,
nothing really special here."
Beyond that, there are the usual big batches of updates to ath9k, b43,
mwifiex, and wil6210 as well as a handful of other bits here and there.
Also, rtlwifi gets some btcoexist attention from Larry.
Please let me know if there are problems!
====================
Had to adjust the wil6210 code to comply with Joe Perches's recent
change in net-next to make the netdev_*() routines return void instead
of 'int'.
