We're using edac_mc_workq_setup() both on the init path, when
we load an edac driver and when we change the polling period
(edac_mc_reset_delay_period) through /sys/.../edac_mc_poll_msec.
On that second path we don't need to init the workqueue which has been
initialized already.
Thanks to Tejun for workqueue insights.

Sanitize code even more to accept unsigned longs only and to not allow
polling intervals below 1 second as this is unnecessary and doesn't make
much sense anyway for polling errors.

Pull Xen bugfixes from Konrad Rzeszutek Wilk:
"This has an healthy amount of code being removed - which we do not use
anymore (the only user of it was ia64 Xen which had been removed
already). The other bug-fixes are to make Xen ARM be able to use the
new event channel mechanism and proper export of header files to
user-space.
Summary:
- Fix ARM and Xen FIFO not working.
- Remove more Xen ia64 vestigates.
- Fix UAPI missing Xen files"

"Here is some powerpc goodness for -rc2. Arguably -rc1 material more

It's mostly bug fixes including regressions, but there are a couple of

One is a straightforward patch from Michael to add a bunch of P8 cache
events to perf.
The other one is a patch by myself to add the direct DMA (iommu
bypass) for PCIe on Power8 for 64-bit capable devices. This has been
around for a while, I had lost track of it. However it's been in our
internal kernels we use for testing P8 already and it affects only P8
related code. Since P8 is still unreleased the risk is pretty much
nil at this point"

Commit fc087e10734a4d3e40693fc099461ec1270b3fff (xen/events: remove
unnecessary init_evtchn_cpu_bindings()) causes a regression.
The kernel-side VCPU binding was not being correctly set for newly
allocated or bound interdomain events. In ARM guests where 2-level
events were used, this would result in no interdomain events being
handled because the kernel-side VCPU masks would all be clear.
x86 guests would work because the irq affinity was set during irq
setup and this would set the correct kernel-side VCPU binding.
Fix this by properly initializing the kernel-side VCPU binding in
bind_evtchn_to_irq().

The powerpc specific nx-842 compression driver does not currently
handle translating a vmalloc address to a physical address.
The current driver uses __pa() for all addresses which does not
properly handle vmalloc addresses and thus causes a failure since
we do not pass a proper physical address to the hypervisor.
This patch adds a routine to convert an address to a physical
address by checking for vmalloc addresses and handling them properly.

John W. Linville says:
====================
Please pull this batch of fixes intended for the 3.14 stream!
For the mac80211 bits, Johannes says:
"This is just a collection of small fixes, the commit logs explain the
details. The only thing that isn't strictly a fix is the 5/10 MHz
enabling, I had forgotten this and there's little point in waiting
longer. The patch simply removes the force-disable code that I put in
when there was a problem with the userspace API (that has long been
fixed.)"
For the iwlwifi bits, Emmanuel says:
"I have an important fix that disables A band in case the driver thought
it was enabled, and the firmware disagreed. We ended up making the
firmware unhappy. I also fix the station table in AP mode and fix the
scan while we have BT working.
Johannes removes a static variable that could potentially lead to to
issues on multi-device setups and disables scheduled scan to avoid
issues with old versions of wpa_supplicant.
A small fix from David on scan and a few new device IDs for 7265."
On top of that...
Oleksij Rempel adds a USB ID to the ar5523 driver and changes the
default powersave setting for ath9k_htc to "off", due to observed
stability issues (based on an equivalent ath9k patch).
Stanislaw Gruszka similarly disables powersave for a couple of rt2x00
drivers. He also fixes a couple of scheduling while atomic issues
in ath9k_htc.
Sujith Manoharan rounds-out the powersave disables with one for ath9k.
He also fixes a build prolem with ath9k on ARM and fixes an ath9k Tx
power calculation.
Finally, Andrea Merello fixes a couple of lingering DMA mapping
problems in the rtl8180 driver.

While we are at it, don't do kmap() under kmap_atomic(), *especially*
for a page we'd allocated with GFP_KERNEL. It's spelled "page_address",
and had that been more than that, we'd have a real trouble - kmap_high()
can block, and doing that while holding kmap_atomic() is a Bad Idea(tm).

Apparently it's broken in the exact same way as the gmbus irq. For
reference of the full story see
commit c12aba5aa0e60b7947bc8b6ea25ef55c4acf81a4

drm/i915: stop using GMBUS IRQs on Gen4 chips
The effect is that we have a storm of unclaimed interrupts on the
legacy irq line. If that one is used by a different device then the
kernel will complain and rather quickly kill the irq source. Which
breaks any device trying to actually use the legacy irq line.
This regression has been introduced
commit 4aeebd7443e36b0a40032e518a9338f48bd27efc

drm/i915: dp aux irq support for g4x/vlv
Note that disabling MSI works around the issue, but we can't do that
since apparently then the hw will miss interrupts. At least if
relevant comments in i915_irq.c are accurate.
v2: Cross-reference dp aux and gmbus gen4 comments.
v3: Consolidate harder into i915_drv.h as suggested by Chris.

Stick the label inside the same #ifdef that the code which calls
it uses. Note that this is only seen for arch that do not set
ARCH_HAS_IOREMAP_WC, such as arm, mips, sparc, ..., as the others
enable the write combining code and hence use the label.

It seems like this function was intended to have special handling for
urb statuses of -ENOENT and -ECONNRESET. But now it just prints some
debugging and returns at the start of the function.
I have removed the dead code, it's still in the git history if anyone
wants to revive it.
