Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - nommu updates from Afzal Mohammed cleaning up the vectors support - allow DMA memory "mapping" for nommu Benjamin Gaignard - fixing a correctness issue with R_ARM_PREL31 relocations in the module linker - add strlen() prototype for the decompressor - support for DEBUG_VIRTUAL from Florian Fainelli - adjusting memory bounds after memory reservations have been registered - unipher cache handling updates from Masahiro Yamada - initrd and Thumb Kconfig cleanups * 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (23 commits) ARM: mm: round the initrd reservation to page boundaries ARM: mm: clean up initrd initialisation ARM: mm: move initrd init code out of arm_memblock_init() ARM: 8655/1: improve NOMMU definition of pgprot_*() ARM: 8654/1: decompressor: add strlen prototype ARM: 8652/1: cache-uniphier: clean up active way setup code ARM: 8651/1: cache-uniphier: include <linux/errno.h> instead of <linux/types.h> ARM: 8650/1: module: handle negative R_ARM_PREL31 addends correctly ARM: 8649/2: nommu: remove Hivecs configuration is asm ARM: 8648/2: nommu: display vectors base ARM: 8647/2: nommu: dynamic exception base address setting ARM: 8646/1: mmu: decouple VECTORS_BASE from Kconfig ARM: 8644/1: Reduce "CPU: shutdown" message to debug level ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbol ARM: 8640/1: Add support for CONFIG_DEBUG_VIRTUAL ARM: 8639/1: Define KERNEL_START and KERNEL_END ARM: 8638/1: mtd: lart: Rename partition defines to be prefixed with PART_ ARM: 8637/1: Adjust memory boundaries after reservations ARM: 8636/1: Cleanup sanity_check_meminfo ARM: add CPU_THUMB_CAPABLE to indicate possible Thumb support ...
