Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King: "This set includes adding support for Neon acceleration of RAID6 XOR code from Ard Biesheuvel, cache flushing and barrier updates from Will Deacon, and a cleanup to the ARM debug code which reduces the amount of code by about 500 lines. A few other cleanups, such as constifying the machine descriptors which already shouldn't be written to, cleaning up the printing of the L2 cache size" * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (55 commits) ARM: 7826/1: debug: support debug ll on hisilicon soc ARM: 7830/1: delay: don't bother reporting bogomips in /proc/cpuinfo ARM: 7829/1: Add ".text.unlikely" and ".text.hot" to arm unwind tables ARM: 7828/1: ARMv7-M: implement restart routine common to all v7-M machines ARM: 7827/1: highbank: fix debug uart virtual address for LPAE ARM: 7823/1: errata: workaround Cortex-A15 erratum 773022 ARM: 7806/1: allow DEBUG_UNCOMPRESS for Tegra ARM: 7793/1: debug: use generic option for ep93xx PL10x debug port ARM: debug: move SPEAr debug to generic PL01x code ARM: debug: move davinci debug to generic 8250 code ARM: debug: move keystone debug to generic 8250 code ARM: debug: remove DEBUG_ROCKCHIP_UART ARM: debug: provide generic option choices for 8250 and PL01x ports ARM: debug: move PL01X debug include into arch/arm/include/debug/ ARM: debug: provide PL01x debug uart phys/virt address configuration options ARM: debug: add support for word accesses to debug/8250.S ARM: debug: move 8250 debug include into arch/arm/include/debug/ ARM: debug: provide 8250 debug uart phys/virt address configuration options ARM: debug: provide 8250 debug uart register shift configuration option ARM: debug: provide 8250 debug uart flow control configuration option ...
