ATU (Address Translation Unit) is a new IOMMU in SPARC supported with
Hypervisor IOMMU v2 APIs.
Current SPARC IOMMU supports only 32bit address ranges and one TSB
per PCIe root complex that has a 2GB per root complex DVMA space
limit. The limit has become a scalability bottleneck nowadays that
a typical 10G/40G NIC can consume 300MB-500MB DVMA space per
instance. When DVMA resource is exhausted, devices will not be usable
since the driver can't allocate DVMA.
ATU removes bottleneck by allowing guest os to create IOTSB of size
32G (or more) with 64bit address ranges available in ATU HW. 32G is
more than enough DVMA space to be shared by all PCIe devices under
root complex contrast to 2G space provided by legacy IOMMU.
ATU allows PCIe devices to use 64bit DMA addressing. Devices
which choose to use 32bit DMA mask will continue to work with the
existing legacy IOMMU.

Commit 2b15af6f95 ("af_unix: use freezable blocking calls in read")
converts schedule_timeout() to its freezable version, it was probably
correct at that time, but later, commit 2b514574f7e8
("net: af_unix: implement splice for stream af_unix sockets") breaks
the strong requirement for a freezable sleep, according to
commit 0f9548ca1091:
We shouldn't try_to_freeze if locks are held. Holding a lock can cause a
deadlock if the lock is later acquired in the suspend or hibernate path
(e.g. by dpm). Holding a lock can also cause a deadlock in the case of
cgroup_freezer if a lock is held inside a frozen cgroup that is later
acquired by a process outside that group.
The pipe_lock is still held at that point.
So use freezable version only for the recvmsg call path, avoid impact for
Android.

This series fixes as number of leaks and issues in the cpsw probe-error

resuming in the probe error path as suggested by Grygorii (patch
1/7).
- Runtime-resume platform device before registering any children in
order to make sure it is synchronously suspended after deregistering
children in the error path (patch 3/7).

An alternative fix is to assure that IFF_UP gets cleared by
calling dev_close() during shutdown. This is similar to what the
bnx2/tg3/xgene and maybe others are doing to assure that the driver
isn't being called following _shutdown().

If the reply to a successful CLOSE call races with an OPEN to the same
file, we can end up scribbling over the stateid that represents the
new open state.
The race looks like:
Client Server
====== ======
CLOSE stateid A on file "foo"
CLOSE stateid A, return stateid C
OPEN file "foo"
OPEN "foo", return stateid B
Receive reply to OPEN
Reset open state for "foo"
Associate stateid B to "foo"
Receive CLOSE for A
Reset open state for "foo"
Replace stateid B with C
The fix is to examine the argument of the CLOSE, and check for a match
with the current stateid "other" field. If the two do not match, then
the above race occurred, and we should just ignore the CLOSE.

Pull GPIO fixes from Linus Walleij:
"These are hopefully the last GPIO fixes for v4.9. The most important
is that it fixes the UML randconfig builds that have been nagging me
for some time and me being confused about where the problem was really
sitting, now this fix give this nice feeling that everything is solid
and builds fine.
Summary:
- Finally, after being puzzled by a bunch of recurrent UML build
failures on randconfigs from the build robot, Keno Fischer nailed
it: GPIO_DEVRES is optional and depends on HAS_IOMEM even though
many users just unconditionally rely on it to be available. And it
*should* be available: garbage collection is nice for this and it
*certainly* has nothing to do with having IOMEM. So we got rid of
it, and now the UML builds should JustWork(TM).
- Do not call .get_direction() on sleeping GPIO chips on the fastpath
when locking GPIOs for interrupts: it is done from atomic context,
no way.
- Some driver fixes"

Recently algif_hash has been changed to allow null hashes. This
triggers a bug when used with an shash algorithm whereby it will
cause a crash during the digest operation.
This patch fixes it by avoiding the digest operation and instead
doing an init followed by a final which avoids the buggy code in
shash.
This patch also ensures that the result buffer is freed after an
error so that it is not returned as a genuine hash result on the
next recv call.
The shash/ahash wrapper code will be fixed later to handle this
case correctly.

Since commit 87a18a6a5652 ("mmc: mmc: Use ->card_busy() to detect busy
cards in __mmc_switch()") the ESDHC driver is broken:
mmc0: Card stuck in programming state! __mmc_switch
mmc0: error -110 whilst initialising MMC card
Since this commit __mmc_switch() uses ->card_busy(), which is
sdhci_card_busy() for the esdhc driver. sdhci_card_busy() uses the
PRESENT_STATE register, specifically the DAT0 signal level bit. But the
ESDHC uses a non-conformant PRESENT_STATE register, thus a read fixup is
required to make the driver work again.

KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured.
But this function can't deals with PMCCFILTR correctly because the evtCount
bits of PMCCFILTR, which is reserved 0, conflits with the SW_INCR event
type of other PMXEVTYPER<n> registers. To fix it, when eventsel == 0, this
function shouldn't return immediately; instead it needs to check further
if select_idx is ARMV8_PMU_CYCLE_IDX.
Another issue is that KVM shouldn't copy the eventsel bits of PMCCFILTER
blindly to attr.config. Instead it ought to convert the request to the
"cpu cycle" event type (i.e. 0x11).
To support this patch and to prevent duplicated definitions, a limited
set of ARMv8 perf event types were relocated from perf_event.c to
asm/perf_event.h.

A modalias of 'ieee1394:ven00000D6Cmo00010060sp' hits units for M-Audio
FireWire Audiophile only. However the unit has two states relevant to
loaded firmware. Initial firmware returns 'FW Audiophile Bootloader',
while functional firmware returns 'FW Audiophile'.
ALSA bebob driver compares the units' model name to strings of 24 characters
by the first 15 characters. This is shorter way to differentiate these two
states but confusing to readers.
This commit improves the code for this point. Kernel stack is consumed more in
call of check_audiophile_booted() by a bit.

It's possible to make scanning consume almost arbitrary amounts
of memory, e.g. by sending beacon frames with random BSSIDs at
high rates while somebody is scanning.
Limit the number of BSS table entries we're willing to cache to
1000, limiting maximum memory usage to maybe 4-5MB, but lower
in practice - that would be the case for having both full-sized
beacon and probe response frames for each entry; this seems not
possible in practice, so a limit of 1000 entries will likely be
closer to 0.5 MB.

if we succeed grabbing the refcount, then
if (err && !xfrm_pol_hold_rcu)
will evaluate to false so this hits last else branch which then
sets policy to ERR_PTR(0).

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
detection and gpadc patches are not strictly fixes, but I wanted to get
binding document typo fixed before it pops up on other boards. The
gpadc one liner was in the same series and I applied and pushed it out
already before noticing it could have waited. The list of changes is:
- Fix omap3 SoC features printed
- Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
- Add missing memory node for torpedo
- Initialize uart4_mask properly to avoid writing garbage to PRM registers
- Fix NULL pointer dereference for omap4 volt_data
- Add alias for omap5 gpadc needed by iio drivers
- Enable omap5 jack headset jack detection and fix it's binding typo
- Add missing memory node for logicpd-som-lv
- Fix wrong SMPS6 voltage for VDD-DDR3 for omap5

The Aspeed SoCs have two BT interfaces : one is IPMI compliant and the
other is H8S/2168 compliant.
The current ipmi/bt-bmc driver implements the IPMI version and we
should reflect its nature in the compatible node name using
'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'. The
latter should be used for a H8S interface driver if it is implemented
one day.
