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"
