Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - fix some kernel-doc warnings - fix stack depot IRQ stack filter - cast memset() byte to unsigned char - explicitly include correct DI includes - fix ARCH_LOW_ADDRESS_LIMIT with CONFIG_ZONE_DMA - fix get_user() problems when linker uses a veneer - make including linux/uaccess.h self-contained on ARM * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 9326/1: make <linux/uaccess.h> self-contained for ARM ARM: 9324/1: fix get_user() broken with veneer ARM: 9323/1: mm: Fix ARCH_LOW_ADDRESS_LIMIT when CONFIG_ZONE_DMA ARM: 9322/1: Explicitly include correct DT includes ARM: 9321/1: memset: cast the constant byte to unsigned char ARM: 9320/1: fix stack depot IRQ stack filter ARM: 9319/1: sa1111: fix sa1111_probe kernel-doc warnings
