The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.
Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.
So initialize flags in this structure too.

which is based off v3.13-rc6. If you would like me to rebase it on
a different branch/tag I would be more than happy to do so.
The patches are all bug-fixes and hopefully can go in 3.14.
They deal with xen-blkback shutdown and cause memory leaks
as well as shutdown races. They should go to stable tree and if you
are OK with I will ask them to backport those fixes.
There is also a fix to xen-blkfront to deal with unexpected state
transition. And lastly a fix to the header where it was using the
__aligned__ unnecessarily.

Whilst trying to bring-up an SMMUv2 implementation with the table
walker plumbed into a coherent interconnect, I noticed that the memory
transactions targetting the CPU caches from the SMMU were marked as
outer-shareable instead of inner-shareable.
After a bunch of digging, it seems that we actually need to program
CBARn.BPSHCFG for s1-s2-bypass contexts to act as non-shareable in order
for the shareability configured in the corresponding TTBCR not to be
overridden with an outer-shareable attribute.

Now that we populate page tables as we traverse them ("iommu/arm-smmu:
fix pud/pmd entry fill sequence"), we need to ensure that we flush out
our zeroed tables after initial allocation, to prevent speculative TLB
fills using bogus data.
This patch adds additional calls to arm_smmu_flush_pgtable during
initial table allocation, and moves the dsb required by coherent table
walkers into the helper.

Commit a44a9791e7 ("iommu/arm-smmu: use mutex instead of spinlock for
locking page tables") replaced the page table spinlock with a mutex, to
allow blocking allocations to satisfy lazy mapping requests.
Unfortunately, it turns out that IOMMU mappings are created from atomic
context (e.g. spinlock held during a dma_map), so this change doesn't
really help us in practice.
This patch is a partial revert of the offending commit, bringing back
the original spinlock but replacing our page table allocations for any
levels below the pgd (which is allocated during domain init) with
GFP_ATOMIC instead of GFP_KERNEL.

The ARM SMMU driver's population of puds and pmds is broken, since we
iterate over the next level of table repeatedly setting the current
level descriptor to point at the pmd being initialised. This is clearly
wrong when dealing with multiple pmds/puds.
This patch fixes the problem by moving the pud/pmd population out of the
loop and instead performing it when we allocate the next level (like we
correctly do for ptes already). The starting address for the next level
is then calculated prior to entering the loop.

After commit 202317a573 (ACPI / scan: Add acpi_device objects for

return 0 for dock devices in dock_notify(), so the dock station
docking code under ACPI_NOTIFY_DEVICE_CHECK will never be executed

"This is just a collection of small fixes, the commit logs explain the

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

Stanislaw Gruszka similarly disables powersave for a couple of rt2x00

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

xHCI 1.0 hosts have a set of requirements on how to align transfer
buffers on the endpoint rings called "TD fragment" rules. When the
ax88179_178a driver added support for scatter gather in 3.12, with
commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts. Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.
Commit 35773dac5f "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this. It was a quick hack to partially
implement the TD fragment rules. However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb. The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.
Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts. Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts. This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

The completion queue is implemented using lockless list.
The llist_add is adds the events to the list head which is a push operation.
The processing of the completion elements is done by disconnecting all the
pushed elements and iterating over the disconnected list. The problem is
that the processing is done in reverse order w.r.t order of the insertion
i.e. LIFO processing. By reversing the disconnected list which is done in
linear time the desired FIFO processing is achieved.
