2013-06-17ARM: cfa10049: Switch the chip select pin of the LCD controllerBrian Lilly
The early prototypes had the chip select pin for the LCD controller wired on the GPIO 3-23, while the production run of the CFA-10049 have this chip select on the GPIO 3-5.

Remove CONFIG_MEMORY_START and CONFIG_MEMORY_SIZE from mach-shmobile. Boards should use DT to specify their memory setup.

Instead of having a hard coded virt-to-phys address conversion code in sleep-sh7372.S, rework the code to do the conversion in C using virt_to_phys().

2013-06-17GPIO: xilinx: Use __raw_readl/__raw_writel IO functionsMichal Simek
This driver can be used on Xilinx ARM Zynq platform where in_be32/out_be32 functions are not implemented. Use __raw_readl/__raw_writel functions which are implemented on Microblaze and PowerPC. For ARM readl/writel functions are used instead. The correct way how to implement this is to detect endians directly on IP. But for the gpio case without interrupt connected(it means without interrupt logic) there are just 2 registers data and tristate where auto detection can't be done.

2013-06-16percpu-refcount: use RCU-sched insted of normal RCUTejun Heo
percpu-refcount was incorrectly using preempt_disable/enable() for RCU critical sections against call_rcu(). 6a24474da8 ("percpu-refcount: consistently use plain (non-sched) RCU") fixed it by converting the preepmtion operations with rcu_read_[un]lock() citing that there isn't any advantage in using sched-RCU over using the usual one; however, rcu_read_[un]lock() for the preemptible RCU implementation - CONFIG_TREE_PREEMPT_RCU, chosen when CONFIG_PREEMPT - are slightly more expensive than preempt_disable/enable(). In a contrived microbench which repeats the followings, - percpu_ref_get() - copy 32 bytes of data into percpu buffer - percpu_put_get() - copy 32 bytes of data into percpu buffer rcu_read_[un]lock() used in percpu_ref_get/put() makes it go slower by about 15% when compared to using sched-RCU. As the RCU critical sections are extremely short, using sched-RCU shouldn't have any latency implications. Convert to RCU-sched.

2013-06-16Merge tag 'iio-for-3.11c' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third round of IIO new stuff, cleanups and staging graduations for the 3.11 cycle. 1) Add clock consumer support and device tree bindings to adf4350. The clock consumer part depends on a not so optional 'optional' implementation of clock_round_rate which is not present for pxa27x. It will be shortly and as no one actually uses this chip with that sub arch as far as we know, no need to delay the inclusion in the meantime. See http://lkml.indiana.edu/hypermail/linux/kernel/1306.1/00023.html for the brief discussion. This may be the first non soc specific driver that makes use of that function. 2) AD7303 DAC new driver. 3) ADIS16130 minor fixes and improvements plus move out of staging. 4) AD7291 improvements to bring it inline with more recent drivers. 5) Update to the sysfs ABI doc to fix some out of date paths.
