Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:

 - StrongARM SA1111 updates to modernise and remove cruft

 - Add StrongARM gpio drivers for board GPIOs

 - Verify size of zImage is what we expect to avoid issues with
   appended DTB

 - nommu updates from Vladimir Murzin

 - page table read-write-execute checking from Jinbum Park

 - Broadcom Brahma-B15 cache updates from Florian Fainelli

 - Avoid failure with kprobes test caused by inappropriately
   placed kprobes

 - Remove __memzero optimisation (which was incorrectly being
   used directly by some drivers)
