Subject: ARM: OMAP: add RCU locking to omap2_set_init_voltage.
opp_find_freq_ceil and opp_get_voltage are documented as requiring
rcu_lock to be held. So hold it.

Subject: ARM: OMAP4: cpuidle: Fix the C-state reporting to cpuidle governor.
OMAP4 cpuidle driver is reporting the state requested by governor
rather than the actually attempted one.
This is obviously misleading sysfs and powertop cpuidle statistics.
Fix it so that stats are reported correctly.

Subject: ARM: OMAP4: Move the barrier memboclk_steal() as part of reserve
callback
arm_memblock_steal() is not suppose to be used outside ->reserve callback.
OMAP barrier errata code was using it outside reserve callback and hence
it was broken.
Move the allocation as part of ->reserve callback to fix the it.

Subject: ARM: OMAP2+: usb-host: fix compile warning
when commit 3528c58 (OMAP: omap_device: when
building return platform_device instead of
omap_device) started returning a platform_device
instead of a omap_device pointer when building
a device, it failed to convert all users introducing
a compile warning when building
arch/arm/mach-omap2/usb-host.c.
This patch fixes that warning.

Subject: ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module
On some omaps twl4030_gpio has a callback to try to initialize
the MMC controller. If twl4030_gpio is compiled as a module,
bad things can happen because the callback function starts
calling functions that are supposed to be marked __init:
Kernel panic - not syncing: Attempted to kill the idle task!
twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
gpiochip_add: registered GPIOs 192 to 209 on device: twl4030
Unable to handle kernel paging request at virtual address b82a4c74
...
Additionally if this does not fail, warnings are produced
about trying to register the MMC multiple times.
Fix this by removing __init from omap_mux_get_by_name,
and add checks if omap2_hsmmc_init() is getting called more
than once.
Note that this will get fixed properly later on by splitting
omap2_hsmmc_init into two functions.

The omap3evm BSP enables a GPIO LED on the twl4030 chip. However,
the static gpio_leds array doesn't have an entry for it. This is
most likely a copy-and-paste error, because it has been in there
since the first commit of the omap3evm BSP (53c5ec31).

Subject: ARM: LPC32xx: serial.c: HW bug workaround
This patch fixes a HW bug by flushing RX FIFOs of the UARTs on init. It was
ported from NXP's git.lpclinux.com tree.

Subject: pxa: magician/hx4700: Convert to gpio-regulator from bq24022
The bq24022 on these machines is a very simple regulator using gpios.
One provides the on/off functionality and a second one is used to
change the current between 100 and 500 mA.
This functionality can also be provided by the more generic gpio-regulator.
Therefore convert both machines which makes it possible to remove the
bq24022 driver later on.
