#     Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
#     
#     Pull ARM updates from Russell King:
#     
#      - add arch/arm/Kbuild from Masahiro Yamada.
#     
#      - simplify act_mm macro, since it contains an open-coded
#        get_thread_info.
#     
#      - VFP updates for Clang from Stefan Agner.
#     
#      - Fix unwinder for Clang from Nathan Huckleberry.
#     
#      - Remove unused it8152 PCI host controller, used by the removed cm-x2xx
#        platforms from Mike Rapoport.
#     
#      - Further explanation of __range_ok().
#     
#      - Remove kimage_voffset that isn't used anymore from Marc Zyngier.
#     
#      - Drop ancient Thumb-2 workaround for old binutils from Ard Biesheuvel.
#     
#      - Documentation cleanup for mach-* from Pete Zaitcev.
