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"

* 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
