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"
