Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "In this set, we have: - Refactoring of some of the old StrongARM-1100 GPIO code to make things simpler by Dmitry Eremin-Solenikov - Read-only and non-executable support for modules on ARM from Laura Abbot - Removal of unnecessary set_drvdata() calls in AMBA code - Some non-executable support for kernel lowmem mappings at the 1MB section granularity, and dumping of kernel page tables via debugfs - Some improvements for the timer/clock code on Footbridge platforms, and cleanup some of the LED code there - Fix fls/ffs() signatures to match x86 to prevent build warnings, particularly where these are used with min/max() macros - Avoid using the bootmem allocator on ARM (patches from Santosh Shilimkar) - Various asid/unaligned access updates from Will Deacon" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (51 commits) ARM: SMP implementations are not supposed to return from smp_ops.cpu_die() ARM: ignore memory below PHYS_OFFSET Fix select-induced Kconfig warning for ZBOOT_ROM ARM: fix ffs/fls implementations to match x86 ARM: 7935/1: sa1100: collie: add gpio-keys configuration ARM: 7932/1: bcm: Add DEBUG_LL console support ARM: 7929/1: Remove duplicate SCHED_HRTICK config option ARM: 7928/1: kconfig: select HAVE_EFFICIENT_UNALIGNED_ACCESS for CPUv6+ && MMU ARM: 7927/1: dcache: select DCACHE_WORD_ACCESS for big-endian CPUs ARM: 7926/1: mm: flesh out and fix the comments in the ASID allocator ARM: 7925/1: mm: keep track of last ASID allocation to improve bitmap searching ARM: 7924/1: mm: don't bother with reserved ttbr0 when running with LPAE ARM: PCI: add legacy IDE IRQ implementation ARM: footbridge: cleanup LEDs code ARM: pgd allocation: retry on failure ARM: footbridge: add one-shot mode for DC21285 timer ARM: footbridge: add sched_clock implementation ARM: 7922/1: l2x0: add Marvell Tauros3 support ARM: 7877/1: use built-in byte swap function ARM: 7921/1: mcpm: remove redundant dsb instructions prior to sev ...
