Input: smtpe-ts - wait 50mS until polling for pen-up
Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.
Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.
The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.
In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

ib/cm: Change reject message type when destroying cm_id
Problem reported by: Ted Kim <ted.h.kim@oracle.com>:
We have a case where a Linux system and a non-Linux system are
trying to interoperate. The Linux host is the active side and
starts the connection establishment, but later decides to not go
through with the connection setup and does rdma_destroy_id().
The rdma_destroy_id() eventually works its way down to cm_destroy_id()
in core/cm.c, where a REJ is sent. The non-Linux system
has some trouble recognizing the REJ because of:
A. CM states which can't receive the REJ
B. Some issues about REJ formatting (missing comm ID)
ISSUE A: That part of the spec says, a Consumer Reject REJ can be
sent for a connection abort, but it goes further
and says: can send a REJ message with a "Consumer Reject"
Reason code if they are in a CM state (i.e. REP
Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows
a REJ to be sent (lines 35-38).
Of the states listed there in that sentence, it would
seem to limit the active side to using the Consumer Reject
(for the abort case) in just the REP-Rcvd and MRA-REP-Sent
states. That is basically only after the active side
sees a REP (or alternatively goes down the state transitions
to timeout in which case a Timeout REJ is sent).
As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case
to the same as REQ-SENT. Essentially, make a REJ sent after
getting an MRA on active side a timeout rather than Consumer-
Reject, which is arguably more correct with the CM state
diagrams previous to getting a REP.

ALSA: hda - Disable widget power-saving for ALC292 & co
We've got reports that ALC3226 (a Dell variant of ALC292) gives click
noises at transition from D3 to D0 when the widget power-saving is
enabled. Further debugging session showed that avoiding it isn't
trivial, unfortunately, since paths are basically activated
dynamically while the pins have been already enabled.

xen/events: don't bind non-percpu VIRQs with percpu chip
A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different
VCPU than it is bound to. This can result in a race between
handle_percpu_irq() and removing the action in __free_irq() because
handle_percpu_irq() does not take desc->lock. The interrupt handler
sees a NULL action and oopses.
Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER).

The PWM hardware on Pistachio platform has a maximum timebase steps
value to 255. To fix it, let's introduce a compatible-specific
data structure to contain the SoC-specific details and use it to
specify a maximum timebase.
Also, let's limit the minimum timebase to 16 steps, to allow a sane
range of duty cycle steps.

ALSA: pcm: Modify double acknowledged interrupts check condition
Currently in snd_pcm_update_hw_ptr0 during interrupt,
we consider there were double acknowledged interrupts when:
1. HW reported pointer is smaller than expected, and
2. Time from last update time (hdelta) is over half a buffer time.
However, when HW reported pointer is only a few bytes smaller than
expected, and when hdelta is just a little larger than half a buffer time
(e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.
The condition #2 uses jiffies, but jiffies is not high resolution
since it is integer. We should consider jiffies inaccuracy.

sched: always use blk_schedule_flush_plug in io_schedule_out
block plug callback could sleep, so we introduce a parameter
'from_schedule' and corresponding drivers can use it to destinguish a
schedule plug flush or a plug finish. Unfortunately io_schedule_out
still uses blk_flush_plug(). This causes below output (Note, I added a
might_sleep() in raid1_unplug to make it trigger faster, but the whole
thing doesn't matter if I add might_sleep). In raid1/10, this can cause
deadlock.
This patch makes io_schedule_out always uses blk_schedule_flush_plug.
This should only impact drivers (as far as I know, raid 1/10) which are
sensitive to the 'from_schedule' parameter.

watchdog: Fix merge 'conflict'
Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.
Commit
195daf665a62 ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d293233 ("watchdog: Add watchdog enable/disable all functions").
There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.
This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.

"One important patch which fixes crashes due to stack randomization on
architectures where the stack grows upwards (currently parisc and
metag only).
This bug went unnoticed on parisc since kernel 3.14 where the flexible
mmap memory layout support was added by commit
9dabf60dc4ab. The
changes in fs/exec.c are inside an #ifdef CONFIG_STACK_GROWSUP section
and will not affect other platforms.
The other two patches rename args of the kthread_arg() function and
fixes a printk output"

Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"
In commit
8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:
http://lkml.kernel.org/g/
20150511224646.GJ32500@ld-irv-0074
It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.
This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.
At the same time, let's move the documentation to a better name.
Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.

- The recent ACPICA commit that set the ACPI _REV return value to 2
(which is the value always used by Windows and now mandated by the
spec too) in order to prevent the firmware people from using it to
play tricks with us caused a serious audio regression to happen on
Dell XPS 13 (the AML on that machine uses the _REV return value to
decide how to expose audio to the OS and does that to hide the lack
of proper support for its I2S audio in Linux), so revert that
commit for now and we'll revisit the issue in the next cycle.
- Ensure that the ordering of acpi_reserve_resources() with respect
to the rest of the ACPI initialization sequence will always be the

registers may be assigned to a PCI host bridge as a result of a

mm, numa: really disable NUMA balancing by default on single node machines
NUMA balancing is meant to be disabled by default on UMA machines but
the check is using nr_node_ids (highest node) instead of
num_online_nodes (online nodes).
The consequences are that a UMA machine with a node ID of 1 or higher
will enable NUMA balancing. This will incur useless overhead due to
minor faults with the impact depending on the workload. These are the
impact on the stats when running a kernel build on a single node machine
whose node ID happened to be 1:

memory that is reserved at boot time (not in buddy system). So add a
check before accessing it.
