  ARM: 6321/1: fix syntax error in main Kconfig file
  ARM: 6297/1: move U300 timer to dynamic clock lookup
  ARM: 6296/1: clock U300 intcon and timer properly
  ARM: 6295/1: fix U300 apb_pclk split

  ARM: 6299/1: errata: TLBIASIDIS and TLBIMVAIS operations can broadcast a faulty ASID
  ARM: 6294/1: etm: do a dummy read from OSSRR during initialization
  ARM: 6292/1: coresight: add ETM management registers
  ARM: 6288/1: ftrace: document mcount formats
  ARM: 6287/1: ftrace: clean up mcount assembly indentation
  ARM: 6286/1: fix Thumb-2 decompressor broken by "Auto calculate ZRELADDR"
  ARM: 6281/1: video/imxfb.c: allow usage without BACKLIGHT_CLASS_DEVICE
  ARM: 6280/1: imx: Fix build failure when including <mach/gpio.h> without <linux/spinlock.h>
  ARM: S5PV210: Fix on missing s3c-sdhci card detection method for hsmmc3
  ARM: S5P: Fix on missing S5P_DEV_FIMC in plat-s5p/Kconfig
  ARM: S5PV210: Override FIMC driver name on Aquila board
  ARM: S5PC100: enable FIMC on SMDKC100
  ...

Fix up conflicts in arch/arm/mach-{s5pc100,s5pv210}/cpu.c due to
different subsystem 'setname' calls, and trivial port types in
include/linux/serial_core.h
