Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"A few fixes for the recently merged development updates:
- the update to convert a code branch in the procinfo structure
forgot to update the nommu code.
- VDSO only supported for V7 CPUs and later.
- VDSO build creates files which should be ignored by git but are not.
- ensure that make arch/arm/vdso/ doesn't build if it isn't enabled"
