Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "Another set of small fixes for ARM, covering various areas.

  Laura fixed a long standing issue with virt_addr_valid() failing to
  handle holes in memory.  Steve found a problem with dcache flushing
  for compound pages.  I fixed another bug in footbridge stuff causing
  time to tick slowly, and also a problem with the AES code which can
  cause linker errors.

  A patch from Rob which fixes Xen problems induced by a lack of
  consistency in our naming of ioremap_cache() - which thankfully has
  very few users"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 7933/1: rename ioremap_cached to ioremap_cache
  ARM: fix "bad mode in ... handler" message for undefined instructions
  CRYPTO: Fix more AES build errors
  ARM: 7931/1: Correct virt_addr_valid
  ARM: 7923/1: mm: fix dcache flush logic for compound high pages
  ARM: fix footbridge clockevent device
