677d13f27e leds: leds-mc13783: Use proper "max_brightness" value fo LEDs
Instead of using maximum value of 255 and shift it to appropriate
LED duty cycle, this patch introduce a helper to use proper maximum
value for each LED.

8d82fef8bb leds: Turn off led if blinking is disabled
When using the timer trigger and setting delay_on to 0, the led
will stay in whatever state is was in, while intuitively one
would expect it to turn off. This patch changes the behaviour to
turn it off.

fba14ae8e9 ledtrig-cpu: Handle CPU hot(un)plugging
When CPU is hot(un)plugged, no syscore notification is being
generated, nor is cpuidle involved. This leaves the CPU LED
turned on, because the dying thread is doing some work (LED on)
and than it is... well, dying (LED still on :-)

Added notifier block for hot(un)plugging operations, generating
existing trigger events.

7267342995 ARM: SoC fixes for 3.14-rc
A collection of fixes for ARM platforms. Most are fixes for DTS files,
 mostly from DT conversion on OMAP which is still finding a few issues here
 and there.
 
 There's a couple of small stale code removal patches that we usually
 queue for the next release instead, but they seemed harmless enough to
 bring in now.
 
 Also, a fix for backlight on some PXA platforms, and a cache configuration
 fix for Tegra, etc.

Pull xfs fixes from Dave Chinner:
 "This is the first pull request I've had to do for you, so I'm still
  sorting things out.  The reason I'm sending this and not Ben should be
  obvious from the first commit below - SGI has stepped down from the
  XFS maintainership role.  As such, I'd like to take another
  opportunity to thank them for their many years of effort maintaining
  XFS and supporting the XFS community that they developed from the
  ground up.

  So I haven't had time to work things like signed tags into my
  workflows yet, so this is just a repo branch I'm asking you to pull
  from.  And yes, I named the branch -rc4 because I wanted the fixes in
  rc4, not because the branch was for merging into -rc3.  Probably not
  right, either.

  Anyway, I should have everything sorted out by the time the next merge
  window comes around.  If there's anything that you don't like in the
  pull req, feel free to flame me unmercifully.

  The changes are fixes for recent regressions and important thinkos in
  verification code:

        - a log vector buffer alignment issue on ia32
        - timestamps on truncate got mangled
        - primary superblock CRC validation fixes and error message
          sanitisation"

* 'xfs-fixes-for-3.14-rc4' of git://oss.sgi.com/xfs/xfs:
  xfs: limit superblock corruption errors to actual corruption
  xfs: skip verification on initial "guess" superblock read

  xfs: ensure correct log item buffer alignment
  xfs: ensure correct timestamp updates from truncate

10527106ab Device tree compatible match order bug fix
This branch contains a bug fix for the way devicetree code identifies
 the type of device. Device drivers can contain a list of of_device_ids,
 but it more than one entry will match, then the device driver may choose
 the wrong one. Commit 105353145e, "match each node compatible against
 all given matches first", was queued for v3.14 but ended up causing
 other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs.
 Merely reverting the fix and waiting until v3.15 isn't a good option
 because there is code in v3.14 that depends on the revised behaviour to
 boot.
 
 This branch should finally fixes the problem correctly. This time
 instead of just hoping that the patch is correct, this branch also adds
 new testcases that validate the behaviour.
 
 The changes in this branch are larger than I would like for a -rc pull,
 but moving the test case data out of out of arch/arm so that it could be
 validated on other architectures was important.

4efbc454ba sched: Fix information leak in sys_sched_getattr()
We're copying the on-stack structure to userspace, but forgot to give
the right number of bytes to copy. This allows the calling process to
obtain up to PAGE_SIZE bytes from the stack (and possibly adjacent
kernel memory).

This fix copies only as much as we actually have on the stack
(attr->size defaults to the size of the struct) and leaves the rest of
the userspace-provided buffer untouched.

Found using kmemcheck + trinity.

4df1638cfa sched/deadline: Fix overflow to handle period==0 and deadline!=0
While debugging the crash with the bad nr_running accounting, I hit
another bug where, after running my sched deadline test, I was getting
failures to take a CPU offline. It was giving me a -EBUSY error.

Adding a bunch of trace_printk()s around, I found that the cpu
notifier that called sched_cpu_inactive() was returning a failure. The
overflow value was coming up negative?

Talking this over with Juri, the problem is that the total_bw update was
suppose to be made by dl_overflow() which, during my tests, seemed to
not be called. Adding more trace_printk()s, it wasn't that it wasn't
called, but it exited out right away with the check of new_bw being
equal to p->dl.dl_bw. The new_bw calculates the ratio between period and
runtime. The bug is that if you set a deadline, you do not need to set
a period if you plan on the period being equal to the deadline. That
is, if period is zero and deadline is not, then the system call should
set the period to be equal to the deadline. This is done elsewhere in
the code.

The fix is easy, check if period is set, and if it is not, then use the
deadline.

when I was able to reproduce the bug with just my stress-cpu-hotplug
test. This bug baffled me because it would not always trigger, and
would only trigger on the first run after boot up. The
stress-cpu-hotplug test would crash hard the first run, or never crash
at all. But a new reboot may cause it to crash on the first run again.

I spent all week bisecting this, as I couldn't find a consistent
reproducer. I finally narrowed it down to the sched deadline patches,
and even more peculiar, to the commit that added the sched
deadline boot up self test to the latency tracer. Then it dawned on me
to what the bug was.

All it took was to run a task under sched deadline to screw up the CPU
hot plugging. This explained why it would lock up only on the first run
of the stress-cpu-hotplug test. The bug happened when the boot up self
test of the schedule latency tracer would test a deadline task. The
deadline task would corrupt something that would cause CPU hotplug to
fail. If it didn't corrupt it, the stress test would always work
(there's no other sched deadline tasks that would run to cause
problems). If it did corrupt on boot up, the first test would lockup
hard.

I proved this theory by running my deadline test program on another box,
and then run the stress-cpu-hotplug test, and it would now consistently
lock up. I could run stress-cpu-hotplug over and over with no problem,
but once I ran the deadline test, the next run of the
stress-cpu-hotplug would lock hard.

After adding lots of tracing to the code, I found the cause. The
function tracer showed that migrate_tasks() was stuck in an infinite
loop, where rq->nr_running never equaled 1 to break out of it. When I
added a trace_printk() to see what that number was, it was 335 and
never decrementing!

Looking at the deadline code I found:

static void __dequeue_task_dl(struct rq *rq, struct task_struct *p, int flags) {
	dequeue_dl_entity(&p->dl);
	dequeue_pushable_dl_task(rq, p);
}

static void dequeue_task_dl(struct rq *rq, struct task_struct *p, int flags) {
	update_curr_dl(rq);
	__dequeue_task_dl(rq, p, flags);

	dec_nr_running(rq);
}

And this:

	if (dl_runtime_exceeded(rq, dl_se)) {
		__dequeue_task_dl(rq, curr, 0);
		if (likely(start_dl_timer(dl_se, curr->dl.dl_boosted)))
			dl_se->dl_throttled = 1;
		else
			enqueue_task_dl(rq, curr, ENQUEUE_REPLENISH);

		if (!is_leftmost(curr, &rq->dl))
			resched_task(curr);
	}

Notice how we call __dequeue_task_dl() and in the else case we
call enqueue_task_dl()? Also notice that dequeue_task_dl() has
underscores where enqueue_task_dl() does not. The enqueue_task_dl()
calls inc_nr_running(rq), but __dequeue_task_dl() does not. This is
where we get nr_running out of sync.

[snip]

Another point where nr_running can get out of sync is when the dl_timer
fires:

	dl_se->dl_throttled = 0;
	if (p->on_rq) {
		enqueue_task_dl(rq, p, ENQUEUE_REPLENISH);
		if (task_has_dl_policy(rq->curr))
			check_preempt_curr_dl(rq, p, 0);
		else
			resched_task(rq->curr);

This patch does two things:

 - correctly accounts for throttled tasks (that are now considered
   !running);

 - fixes the bug, updating nr_running from {inc,dec}_dl_tasks(),
   since we risk to update it twice in some situations (e.g., a
   task is dequeued while it has exceeded its budget).

7777d93489 IOMMU Fixes for Linux v3.14-rc3
The fixes are only for the ARM-SMMU driver. Here is the summary from
 Will Deacon:
 
   - Andreas Herrmann took the driver for a run with a real SATA
     controller, which caused the new mutex-based locking to explode
     since we require mappings in atomic context
 
   - Yifan fixed an issue with the page table creation, which then caused
     breakages with the way in which we flush descriptors out to the
     table walker
 
   - I ran the driver on a system where the SMMU is hooked into a
     coherent interconnect for table walks, and noticed a shareability
     mismatch between the CPU and the SMMU
 
 These issues are all fixed here and have been tested on both arm and
 arm64 based systems.
 
 Besides that I put a fix on-top to make the spinlock irq-safe, so that the
 code-paths can be used in the DMA-API.
