Pull ARM fixes from Russell King:
 "A number of smallish fixes scattered around the ARM code.  Probably
  the most serious one is the one from Al addressing the missing locking
  in the swap emulation code."

* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
  ARM: 7607/1: realview: fix private peripheral memory base for EB rev. B boards
  ARM: 7606/1: cache: flush to LoUU instead of LoUIS on uniprocessor CPUs
  ARM: missing ->mmap_sem around find_vma() in swp_emulate.c
  ARM: 7605/1: vmlinux.lds: Move .notes section next to the rodata
  ARM: 7602/1: Pass real "__machine_arch_type" variable to setup_machine_tags() procedure
  ARM: 7600/1: include CONFIG_DEBUG_LL_INCLUDE rather than mach/debug-macro.S
