3cb920a151 ARM: ux500: Apply tc3589x's GPIO/IRQ properties to HREF's DT
This patch ensures the tc3589x and tc3598x-gpio devices are
rightfully given interrupt controller status. We also describe
the tc3598x-gpio GPIO expander in full and specify it as a GPIO
controller. Finally we reference that the external MMC slot's
Card Detection GPIO on the HREF is located on the tc3598x-gpio
expander.

39b740bf14 ARM: ux500: Rename MSP board file to something more meaningful
The 'msp' board file does more than just register MSP devices. It
also registers some other components necessary to get audio working
on ux500 based platforms; such as the PCM and Machine Drivers. For
that reason we're changing the filename to be more encompassing -
'audio'.

d524fa7ff6 ARM: ux500: Add i2c configurations to the Device Tree for DB8500 based devices
Since initial support was provided for the Nomadik I2C driver, it
has been converted to an AMBA device. AMBA devices are probed in
a slightly different way to other devices, so we have to identify
them using an "arm,primecell" compatible string. As well as doing
just that, this patch specifies which regulators the controller
should use and requests a clock-speed. The latter is provided as
more of an example, as it's the same as the recently changed
default configuration.

It's understood that the AB8500 should be subordinate to the DB8500;
however, the AB8500 uses the GIC as it's interrupt controller. If
we do not specify which IRQ controller to use the default is to use
the next encountered IRQ controller as we climb the tree. This would
be the DB8500. This patch ensures the AB8500 makes use of the correct
interrupt controller.

When booting with Device Tree we need a way to call-back to the
DB8500 PMU IRQ handler. This is necessary because the two CPU
IRQ lines are muxed together on the DB8500 chip. The DB8500
PMU IRQ handler contains logic to pass over to the other core
in the case of IRQ_NONE. This patch allows the DB8500 PMU IRQ
handler to be passed to Perf through platform data.

In the initial submission of the MSP driver msp1 and msp3's associated

identifier which is passed from platform_data/Device Tree which indicates
which ports should use pinctrl.

f3d8752497 arm: mm: fix DMA pool affiliation check
The __free_from_pool() function was changed in
e9da6e9905. Unfortunately, the test that
checks whether the provided (start,size) is within the DMA pool has
been improperly modified. It used to be:

  if (start < coherent_head.vm_start || end > coherent_head.vm_end)

Where coherent_head.vm_end was non-inclusive (i.e, it did not include
the first byte after the pool). The test has been changed to:

  if (start < pool->vaddr || start > pool->vaddr + pool->size)

So now pool->vaddr + pool->size is inclusive (i.e, it includes the
first byte after the pool), so the test should be >= instead of >.

This bug causes the following message when freeing the *first* DMA
coherent buffer that has been allocated, because its virtual address
is exactly equal to pool->vaddr + pool->size :

beafa0de3d ARM: 7529/1: delay: set loops_per_jiffy when moving to timer-based loop
The delay functions may be called by some platforms between switching to
the timer-based delay loop but before calibration. In this case, the
initial loops_per_jiffy may not be suitable for the timer (although a
compromise may be achievable) and delay times may be considered too
inaccurate.

This patch updates loops_per_jiffy when switching to the timer-based
delay loop so that delays are consistent prior to calibration.

ad72907acd ARM: 7528/1: uaccess: annotate [__]{get,put}_user functions with might_fault()
The user access functions may generate a fault, resulting in invocation
of a handler that may sleep.

This patch annotates the accessors with might_fault() so that we print a
warning if they are invoked from atomic context and help lockdep keep
track of mmap_sem.

The {get,put}_user macros don't perform range checking on the provided
__user address when !CPU_HAS_DOMAINS.

This patch reworks the out-of-line assembly accessors to check the user
address against a specified limit, returning -EFAULT if is is out of
range.

[will: changed get_user register allocation to match put_user]
[rmk: fixed building on older ARM architectures]

Pull DMA-mapping fixes from Marek Szyprowski:
 "Another set of fixes for ARM dma-mapping subsystem.

  Commit e9da6e9905 replaced custom consistent buffer remapping code
  with generic vmalloc areas.  It however introduced some regressions
  caused by limited support for allocations in atomic context.  This
  series contains fixes for those regressions.

  For some subplatforms the default, pre-allocated pool for atomic
  allocations turned out to be too small, so a function for setting its
  size has been added.

  Another set of patches adds support for atomic allocations to
  IOMMU-aware DMA-mapping implementation.

  The last part of this pull request contains two fixes for Contiguous
  Memory Allocator, which relax too strict requirements."

get_user may fail to load from the provided __user address due to an
unhandled fault generated by the access.

In the case of the undefined instruction trap, this results in failure
to load the faulting instruction, in which case we should send SIGILL to
the task rather than continue with potentially uninitialised data.

e534e871a9 ARM: OMAP4: Fix array size for irq_target_cpu
If NR_IRQS is less than MAX_IRQS, we end up writing past the
irq_target_cpu array in omap_wakeupgen_init():

/* Associate all the IRQs to boot CPU like GIC init does. */
for (i = 0; i < max_irqs; i++)
	irq_target_cpu[i] = boot_cpu;

This can happen if SPARSE_IRQ is enabled as by default NR_IRQS is
set to 16. Without this patch we're overwriting other data during
the boot.

Looks like a similar fix was posted by Benoit Cousson earlier
as "ARM: OMAP2+: wakeupgen: Fix wrong array size for irq_target_cpu"
but was lost.
