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

Browse Source 
Pull ARM fixes from Russell King:
 "A number of low impact fixes, the most noticable one is the thumb2
  frame pointer fix.  We also fix a regression caused during this merge
  window with ARM925 CPUs running with caches disabled, and fix a number
  of warnings"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: arm925: ensure assembly sets up writethrough mapping
  ARM: perf: fix compiler warning with gcc 4.6.4 (and tidy code)
  ARM: l2c: fix dependencies on PL310 errata symbols
  ARM: 8069/1: Make thread_save_fp macro aware of THUMB2 mode
  ARM: 8068/1: scoop: Remove unused variable
