Pull arm64 fixes from Will Deacon:
"Apologies for this being so late, but we've uncovered a few nasty
issues on arm64 which didn't settle down until yesterday and the fixes
all look suitable for 4.3. Of the four patches, three of them are
Cc'd to stable, with the remaining patch fixing an issue that only
took effect during the merge window.
Summary:
- Fix corruption in SWP emulation when STXR fails due to contention
- Fix MMU re-initialisation when resuming from a low-power state
- Fix stack unwinding code to match what ftrace expects
- Fix relocation code in the EFI stub when DRAM base is not 2MB aligned"

After commit 566c09c53455 ("raid5: relieve lock contention in get_active_stripe()")
__find_stripe() is called under conf->hash_locks + hash.
But handle_stripe_clean_event() calls remove_hash() under
conf->device_lock.
Under some cirscumstances the hash chain can be circuited,
and we get an infinite loop with disabled interrupts and locked hash
lock in __find_stripe(). This leads to hard lockup on multiple CPUs
and following system crash.
I was able to reproduce this behavior on raid6 over 6 ssd disks.
The devices_handle_discard_safely option should be set to enable trim
support. The following script was used:
for i in `seq 1 32`; do
dd if=/dev/zero of=large$i bs=10M count=100 &
done
neilb: original was against a 3.x kernel. I forward-ported
to 4.3-rc. This verison is suitable for any kernel since
Commit: 59fc630b8b5f ("RAID5: batch adjacent full stripe write")

rbd requires stable pages, as it performs a crc of the page data before
they are send to the OSDs.
But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0
"mm: only enforce stable page writes if the backing device requires
it") it is not assumed anymore that block devices require stable pages.
This patch sets the necessary flag to get stable pages back for rbd.
In a ceph installation that provides multiple ext4 formatted rbd
devices "bad crc" messages appeared regularly (ca 1 message every 1-2
minutes on every OSD that provided the data for the rbd) in the
OSD-logs before this patch. After this patch this messages are pretty
much gone (only ca 1-2 / month / OSD).

Now that we added special handling to the C files in libstub, move
the one remaining arm64 specific EFI stub C file to libstub as
well, so that it gets the same treatment. This should prevent future
changes from resulting in binaries that may execute incorrectly in
UEFI context.
With efi-entry.S the only remaining EFI stub source file under
arch/arm64, we can also simplify the Makefile logic somewhat.

====================
pull request (net-next): ipsec-next 2015-10-30
1) The flow cache is limited by the flow cache limit which
depends on the number of cpus and the xfrm garbage collector
threshold which is independent of the number of cpus. This
leads to the fact that on systems with more than 16 cpus
we hit the xfrm garbage collector limit and refuse new
allocations, so new flows are dropped. On systems with 16
or less cpus, we hit the flowcache limit. In this case, we
shrink the flow cache instead of refusing new flows.
We increase the xfrm garbage collector threshold to INT_MAX
to get the same behaviour, independent of the number of cpus.
2) Fix some unaligned accesses on sparc systems.
From Sowmini Varadhan.
3) Fix some header checks in _decode_session4. We may call
pskb_may_pull with a negative value converted to unsigened
int from pskb_may_pull. This can lead to incorrect policy
lookups. We fix this by a check of the data pointer position
before we call pskb_may_pull.
4) Reload skb header pointers after calling pskb_may_pull
in _decode_session4 as this may change the pointers into
the packet.
5) Add a missing statistic counter on inner mode errors.
Please pull or let me know if there are problems.

====================
NFC 4.4 pull request
This is the NFC pull request for 4.4.
It's a bit bigger than usual, the 3 main culprits being:
- A new driver for Intel's Fields Peak NCI chipset. In order to
support this chipset we had to export a few NCI routines and
extend the driver NCI ops to not only support proprietary
commands but also core ones.
- Support for vendor commands for both STM drivers, st-nci
and st21nfca. Those vendor commands allow to run factory tests
through the NFC netlink interface.
- New i2c and SPI support for the Marvell driver, together with
firmware download support for this driver's core.
Besides that we also have:
- A few file renames in the STM drivers, to keep the naming
consistent between drivers.
- Some improvements and fixes on the NCI HCI layer, mostly to
properly reach a secure element over a legacy HCI link.
- A few fixes for the s3fwrn5 and trf7970a drivers.

Our IRQ storm detection works when an interrupt handler returns
IRQ_NONE for thousands of consecutive interrupts in a second. It
doesn't hurt to occasionally return IRQ_NONE when the interrupt is
actually genuine.
Drivers should only be returning IRQ_HANDLED if they have actually
*done* something to stop an interrupt from happening — it doesn't just
mean "this really *was* my device".

====================
drivers: xgene: Add support RGMII TX/RX delay configuration
X-Gene RGMII ethernet controller has a RGMII bridge that performs the
task of converting the RGMII signal {RX_CLK,RX_CTL, RX_DATA[3:0]} from
PHY to GMII signal {RX_DV,RX_ER,RX_DATA[7:0]} and vice versa. This
RGMII bridge has a provision to internally delay the input RX_CLK and
the output TX_CLK using configuration registers. This will help in
maintain the CLK-CTL delay relationship in various operating
conditions.
This patch adds support RGMII TX/RX delay configuration.

hashtable
Problem Description:
We can add fdbs pointing to the bridge with NULL ->dst but that has a
few race conditions because br_fdb_insert() is used which first creates
the fdb and then, after the fdb has been published/linked, sets
"is_local" to 1 and in that time frame if a packet arrives for that fdb
it may see it as non-local and either do a NULL ptr dereference in
br_forward() or attach the fdb to the port where it arrived, and later
br_fdb_insert() will make it local thus getting a wrong fdb entry.
Call chain br_handle_frame_finish() -> br_forward():
But in br_handle_frame_finish() in order to call br_forward() the dst
should not be local i.e. skb != NULL, whenever the dst is
found to be local skb is set to NULL so we can't forward it,
and here comes the problem since it's running only
with RCU when forwarding packets it can see the entry before "is_local"
is set to 1 and actually try to dereference NULL.
The main issue is that if someone sends a packet to the switch while
it's adding the entry which points to the bridge device, it may
dereference NULL ptr. This is needed now after we can add fdbs
pointing to the bridge. This poses a problem for
br_fdb_update() as well, while someone's adding a bridge fdb, but
before it has is_local == 1, it might get moved to a port if it comes
as a source mac and then it may get its "is_local" set to 1
This patch changes fdb_create to take is_local and is_static as
arguments to set these values in the fdb entry before it is added to the
hash. Also adds null check for port in br_forward.
Fixes: 3741873b4f73 ("bridge: allow adding of fdb entries pointing to the bridge device")

Extend the pxa2xx_spi_acpi_get_pdata() so that it can create platform data
also on platforms that do not support ACPI or if CONFIG_ACPI is not set.
Now it is expected that "pxa2xx-spi" platform device is either created with
explicit platform data or has an ACPI companion device.
However there is only little in pxa2xx_spi_acpi_get_pdata() that is really
dependent on ACPI companion and it can be reworked to cover also cases
where "pxa2xx-spi" device doesn't have ACPI companion and is created
without platform data.
Do this by renaming the pxa2xx_spi_acpi_get_pdata(), moving it outside of
CONFIG_ACPI test and changing a few runtime tests there to support non-ACPI
case. Only port/bus ID setting based on ACPI _UID is dependent on ACPI and
is moved to own function inside CONFIG_ACPI.
Purpose of this to support non-ACPI case for those PCI enumerated compound
devices that integrate both LPSS SPI host controller and integrated DMA
engine under the same PCI ID and which are registered in MFD layer instead
of in spi-pxa2xx-pci.c.

Commit bfebd1cdb497a57757c83f5fbf1a29931591e2a4 ("dm: add full blk-mq
support to request-based DM") moves the initialization of the fields
backing_dev_info.congested_fn, backing_dev_info.congested_data and
queuedata from the function dm_init_md_queue (that is called when the
device is created) to dm_init_old_md_queue (that is called after the
device type is determined).
There is no locking when accessing these variables, thus it is possible
for other parts of the kernel to briefly see this data in a transient
state (e.g. queue->backing_dev_info.congested_fn initialized and
md->queue->backing_dev_info.congested_data uninitialized, resulting in
passing an incorrect parameter to the function dm_any_congested).
This queue data is left initialized for blk-mq devices even though they
that don't use it.
