394ef6403a mm: use vm_unmapped_area() on arm architecture
Update the arm arch_get_unmapped_area[_topdown] functions to make use of
vm_unmapped_area() instead of implementing a brute force search.

b58ed041a3 Device tree changes for v3.8
Bug fixes, little cleanups, and documentation changes. The most invasive
 thing here touches a bunch of the arch directories to use a common build
 rule for .dtb files. There are no major changes to functionality here
 other than a ew new helper functions.

505cbedab9 This is the pinctrl big pull request for v3.8.
As can be seen from the diffstat the major changes
 are:
 
 - A big conversion of the AT91 pinctrl driver and
   the associated ACKed platform changes under
   arch/arm/max-at91 and its device trees. This
   has been coordinated with the AT91 maintainers
   to go in through the pinctrl tree.
 
 - A larger chunk of changes to the SPEAr drivers
   and the addition of the "plgpio" driver for the
   SPEAr as well.
 
 - The removal of the remnants of the Nomadik driver
   from the arch/arm tree and fusion of that into
   the Nomadik driver and platform data header files.
 
 - Some local movement in the Marvell MVEBU drivers,
   these now have their own subdirectory.
 
 - The addition of a chunk of code to gpiolib under
   drivers/gpio to register gpio-to-pin range mappings
   from the GPIO side of things. This has been
   requested by Grant Likely and is now implemented,
   it is particularly useful for device tree work.
 
 Then we have incremental updates all over the place,
 many of these are cleanups and fixes from Axel Lin
 who has done a great job of removing minor mistakes
 and compilation annoyances.

cd587096c0 mmc: omap_hsmmc: Enable HSPE bit for high speed cards
HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.

From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation):

The MMC/SD/SDIO output signals can be driven on either falling edge or
rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows
to reach better timing performance, and thus to increase data transfer
frequency.

There are few pre-requisites for enabling the HSPE bit
- Controller should support High-Speed-Enable Bit and
- Controller should not be using DDR Mode and
- Controller should advertise that it supports High Speed in
  capabilities register and
- MMC/SD clock coming out of controller > 25MHz

The current rules have the .dtb files build in a different directory
from the .dts files. The only reason for this is that it was what
PowerPC has done historically. This patch changes ARM to use the generic
dtb rule which builds .dtb files in the same directory as the source .dts.

ea3aacf5f2 ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event device
The SP804 driver statically initialises the cpumask of the clock event
device to be cpu_all_mask, which is derived from the compile-time
constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback
on the irq_chip, because the common timer code fails to identify the
device as cpu-local and ends up treating it as a broadcast device
instead.

This patch fixes the problem by using cpu_possible_mask at runtime,
which will correctly represent the possible CPUs when SMP_ON_UP is being
used.

5010192d5a ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above
Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

0d2c9f0517 IXP4xx: use __iomem for MMIO
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not

Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.

Without this patch, building ixp4xx_defconfig results in:

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

5d3df93542 Dove: Attempt to fix PMU/RTC interrupts
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

91280e755a ARM: EXYNOS: PL330 MDMA1 fix for revision 0 of Exynos4210 SOC
Commit 8214513 ("ARM: EXYNOS: fix address for EXYNOS4 MDMA1")
changed EXYNOS specific setup of PL330 DMA engine to use 'non-secure'
mdma1 address instead of 'secure' one (from 0x12840000 to 0x12850000)
to fix issue with some Exynos4212 SOCs.  Unfortunately it brakes
PL330 setup for revision 0 of Exynos4210 SOC (mdma1 device cannot
be found at 'non-secure' address):

[    0.566245] dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !
[    0.566278] dma-pl330: probe of dma-pl330.2 failed with error -22

Fix it by using 'secure' mdma1 address on Exynos4210 revision 0 SOC.

e37212aa5d ARM: davinci: dm644x: fix out range signal for ED
Fix the video clock setting when custom timings are used with
pclock <= 27MHz. Existing video clock selection uses PLL2 mode
which results in a 54MHz clock whereas using the MXI mode results
in a 27MHz clock (which is the one actually desired).

This bug affects the Enhanced Definition (ED) support on DM644x.
Without this patch, out-range signals errors are were observed on
the TV when viewing ED. An out-of-range signal is often caused when
the field rate is above the rate that the television will handle.
