commit 12b69a599745fc9e203f61fbb7160b2cc5f479dd upstream.
Various Marvell datasheets advertise second PCIe unit of mv78230
flavour of Armada XP as x4/quad x1 capable. This second unit is in
fact only x1 capable. This patch fixes current mv78230 .dtsi to
reflect that, i.e. makes 1.0 the second interface (instead of 2.0
at the moment). This was successfully tested on a mv78230-based
ReadyNAS 2120 platform with a x1 device (FL1009 XHCI controller)
connected to this second interface.

commit 58e7b1d5826ac6a64b1101d8a70162bc084a7d1e upstream.
With some devices, transfer hangs during I2C frame transmission. This issue
disappears when reducing the internal frequency of the TWI IP. Even if it is
indicated that internal clock max frequency is 66MHz, it seems we have
oversampling on I2C signals making TWI believe that a transfer in progress
is done.
This fix has no impact on the I2C bus frequency.

commit c37dd677988ca50bc8bc60ab5ab053720583c168 upstream.
When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:
[ 7.302154] =====================================

commit 2ba2866f782f7f1c38abc3dd56d3295efd289264 upstream.
pin mux wl12xx_gpio and wl12xx_pins should be part of omap4_pmx_core
and not omap4_pmx_wkup. So, move wl12xx_* to omap4_pmx_core.
Fix the following error message:
pinctrl-single 4a31e040.pinmux: mux offset out of range: 0x38 (0x38)
pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x
SDIO card is not detected after moving pin mux to omap4_pmx_core since
sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card.
This fixes a regression where WLAN did not work after a warm reset
or after one up/down cycle that happened when we move omap4 to boot
using device tree only. For reference, the kernel bug is described at:

commit 5638cabf3e4883f38dfb246c30980cebf694fbda upstream.
There are cases when cryptlen can be zero in crypto_ccm_auth():
-encryptiom: input scatterlist length is zero (no plaintext)
-decryption: input scatterlist contains only the mac
plus the condition of having different source and destination buffers
(or else scatterlist length = max(plaintext_len, ciphertext_len)).
These are not handled correctly, leading to crashes like:

commit 41da8b5adba77e22584f8b45f9641504fa885308 upstream.
The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain
function to chain two scatterlists, but the chain pointer indication
bit is not set. When the resulting scatterlist is used, for example,
by sg_nents to count the number of scatterlist entries, a segfault occurs
because sg_nents does not follow the chain pointer to the chained scatterlist.
Update scatterwalk_sg_chain to set the chain pointer indication bit as is
done by the sg_chain function.

commit 9dda2769af4f3f3093434648c409bb351120d9e8 upstream.
Some s390 crypto algorithms incorrectly use the crypto_tfm structure to

can result in data corruption.
This patch fixes aes-xts by moving the xts and pcc parameter blocks from
the tfm onto the stack (48 + 96 bytes).

commit 1cd9b2f78bf29d5282e02b32f9b3ecebc5842a7c upstream.
It seems that EAPD on NID 0x16 is the only control over all outputs on
HP machines with AD1984A while turning EAPD on NID 0x12 breaks the
output. Thus we need to avoid fiddling EAPD on NID. As a quick
workaround, just set own_eapd_ctrl flag for the wrong EAPD, then
implement finer EAPD controls.

commit d59915d0655c5864b514f21daaeac98c047875dc upstream.
By trial and error, I found this patch could work around an issue
where the headset mic would stop working if you switch between the
internal mic and the headset mic, and the internal mic was muted.
It still takes a second or two before the headset mic actually starts
working, but still better than nothing.
Information update from Kailang:
The verb was ADC digital mute(bit 6 default 1).
Switch internal mic and headset mic will run alc_headset_mode_default.
The coef index 0x11 will set to 0x0041.
Because headset mode was fixed type. It doesn't need to run
alc_determine_headset_type.
So, the value still keep 0x0041. ADC was muted.

The recent kernels got regressions on ASUS W7J with ALC660 codec where
no sound comes out. After a long debugging session, we found out that
setting the pin control on the unused NID 0x10 is mandatory for the

required for other ASUS laptops isn't needed on this machine.

commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream.
The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.
Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.

commit e34ecee2ae791df674dfb466ce40692ca6218e43 upstream.
aio kiocb refcounting was broken - it was relying on keeping track of
the number of available ring buffer entries, which it needs to do
anyways; then at shutdown time it'd wait for completions to be delivered
until the # of available ring buffer entries equalled what it was
initialized to.
Problem with that is that the ring buffer is mapped writable into
userspace, so userspace could futz with the head and tail pointers to
cause the kernel to see extra completions, and cause free_ioctx() to
return while there were still outstanding kiocbs. Which would be bad.
Fix is just to directly refcount the kiocbs - which is more
straightforward, and with the new percpu refcounting code doesn't cost
us any cacheline bouncing which was the whole point of the original
scheme.
Also clean up ioctx_alloc()'s error path and fix a bug where it wasn't
subtracting from aio_nr if ioctx_add_table() failed.

commit a97ad0c4b447a132a322cedc3a5f7fa4cab4b304 upstream.
The current code requires that the scheduled update of the RTC happens
in the closest tick to the half of the second. This seems to be
difficult to achieve reliably. The scheduled work may be missing the
target time by a tick or two and be constantly rescheduled every second.
Relax the limit to 10 ticks. As a typical RTC drifts in the 11-minute
update interval by several milliseconds, this shouldn't affect the
overall accuracy of the RTC much.

commit eb1c160b22655fd4ec44be732d6594fd1b1e44f4 upstream.
The soft lockup below happens at the boot time of the system using dm
multipath and the udev rules to switch scheduler.

This is caused by a race between md device initialization by multipathd and
shell script to switch the scheduler using sysfs.
- multipathd:
SyS_ioctl -> do_vfs_ioctl -> dm_ctl_ioctl -> ctl_ioctl -> table_load
-> dm_setup_md_queue -> blk_init_allocated_queue -> elevator_init
q->elevator = elevator_alloc(q, e); // not yet initialized
- sh -c 'echo deadline > /sys/$DEVPATH/queue/scheduler':
elevator_switch (in the call trace above)
struct elevator_queue *old = q->elevator;
q->elevator = elevator_alloc(q, new_e);
elevator_exit(old); // lockup! (*)
- multipathd: (cont.)
err = e->ops.elevator_init_fn(q); // init fails; q->elevator is modified
(*) When del_timer_sync() is called, lock_timer_base() will loop infinitely
while timer->base == NULL. In this case, as timer will never initialized,
it results in lockup.
This patch introduces acquisition of q->sysfs_lock around elevator_init()
into blk_init_allocated_queue(), to provide mutual exclusion between
initialization of the q->scheduler and switching of the scheduler.
This should fix this bugzilla:

commit 05104a4e8713b27291c7bb49c1e7e68b4e243571 upstream.
The warning for the irq remapping broken check in intel_irq_remapping.c is
pretty pointless. We need the warning, but we know where its comming from, the
stack trace will always be the same, and it needlessly triggers things like
Abrt. This changes the warning to just print a text warning about BIOS being
broken, without the stack trace, then sets the appropriate taint bit. Since we
automatically disable irq remapping, theres no need to contiue making Abrt jump
at this problem

commit f9423606ade08653dd8a43334f0a7fb45504c5cc upstream.
The BUG_ON in drivers/iommu/intel-iommu.c:785 can be triggered from userspace via
VFIO by calling the VFIO_IOMMU_MAP_DMA ioctl on a vfio device with any address
beyond the addressing capabilities of the IOMMU. The problem is that the ioctl code
calls iommu_iova_to_phys before it calls iommu_map. iommu_map handles the case that
it gets addresses beyond the addressing capabilities of its IOMMU.
intel_iommu_iova_to_phys does not.
This patch fixes iommu_iova_to_phys to return NULL for addresses beyond what the
IOMMU can handle. This in turn causes the ioctl call to fail in iommu_map and
(correctly) return EFAULT to the user with a helpful warning message in the kernel
log.

commit 403cfb53fb450d53751fdc7ee0cd6652419612cf upstream.
Some systems although they have firmware class 'M', which usually
needs a work around to not crash, must not be subjected to the
work around because the work around crashes them. They cannot be
told apart by their own device descriptor, but as they are part
of compound devices, can be identified by looking at their siblings.

commit ea78201e2e08f8a91e30100c4c4a908b5cf295fc upstream.
After commit 09fc7d22b024692b2fe8a943b246de1af307132b (usb: musb: fix incorrect
usage of resource pointer), CPPI DMA driver on DaVinci DM6467 can't detect its
dedicated IRQ and so the MUSB IRQ is erroneously used instead. This is because
only 2 resources are passed to the MUSB driver from the DaVinci glue layer, so
fix this by always copying 3 resources (it's safe since a placeholder for the
3rd resource is always there) and passing 'pdev->num_resources' instead of the
size of musb_resources[] to platform_device_add_resources().

This is because raid5d() can be running when the multi-thread
resources are changed via system. We see need to provide locking.
mddev->device_lock is suitable, but we cannot simple call
alloc_thread_groups under this lock as we cannot allocate memory
while holding a spinlock.
So change alloc_thread_groups() to allocate and return the data
structures, then raid5_store_group_thread_cnt() can take the lock
while updating the pointers to the data structures.
This fixes a bug introduced in 3.12 and so is suitable for the 3.12.x
stable series.

commit 72403b4a0fbdf433c1fe0127e49864658f6f6468 upstream.
Commit 0255d4918480 ("mm: Account for a THP NUMA hinting update as one
PTE update") was added to account for the number of PTE updates when
marking pages prot_numa. task_numa_work was using the old return value
to track how much address space had been updated. Altering the return
value causes the scanner to do more work than it is configured or
documented to in a single unit of work.
This patch reverts that commit and accounts for the number of THP
updates separately in vmstat. It is up to the administrator to
interpret the pair of values correctly. This is a straight-forward
operation and likely to only be of interest when actively debugging NUMA
balancing problems.
The impact of this patch is that the NUMA PTE scanner will scan slower
when THP is enabled and workloads may converge slower as a result. On
the flip size system CPU usage should be lower than recent tests
reported. This is an illustrative example of a short single JVM specjbb
test

Check for CAP_SYS_ADMIN since the caller can truncate preallocated
blocks from files they do not own nor have write access to. A more
fine grained access check was considered: require the caller to
specify their own uid/gid and to use inode_permission to check for
write, but this would not catch the case of an inode not reachable
via path traversal from the callers mount namespace.

commit a553e4a6317b2cfc7659542c10fe43184ffe53da ("[PKTGEN]: IPSEC support")
tried to support IPsec ESP transport transformation for pktgen, but acctually
this doesn't work at all for two reasons(The orignal transformed packet has
bad IPv4 checksum value, as well as wrong auth value, reported by wireshark)
- After transpormation, IPv4 header total length needs update,
because encrypted payload's length is NOT same as that of plain text.
- After transformation, IPv4 checksum needs re-caculate because of payload
has been changed.
With this patch, armmed pktgen with below cofiguration, Wireshark is able to
decrypted ESP packet generated by pktgen without any IPv4 checksum error or
auth value error.

Kernel panic - not syncing: Fatal exception in interrupt
This is because the macro operations in smc91x.h defined
for Versatile are missing SMC_outsw() as used in this
commit.
The Versatile needs and uses the same accessors as the other
platforms in the first if(...) clause, just switch it to using
that and we have one problem less to worry about.
This includes a hunk of a patch from Will Deacon fixin
the other 32bit platforms as well: Innokom, Ramses, PXA,
PCM027.
Checkpatch complains about spacing, but I have opted to
follow the style of this .h-file.
