…x-arm

Pull ARM update from Russell King:
 "This is the final round of stuff for ARM, left until the end of the
  merge window to reduce the number of conflicts.  This set contains the
  ARM part of David Howells UAPI changes, and a fix to the ordering of
  'select' statements in ARM Kconfig files (see the appropriate commit
  for why this happened - thanks to Andrew Morton for pointing out the
  problem.)

  I've left this as long as I dare for this window to avoid conflicts,
  and I regenerated the config patch yesterday, posting it to our
  mailing list for review and testing.  I have several acks which
  include successful test reports for it.

  However, today I notice we've got new conflicts with previously unseen
  code...  though that conflict should be trivial (it's my changes vs a
  one liner.)"

* 'late-for-linus' of git://git.linaro.org/people/rmk/linux-arm:
  ARM: config: make sure that platforms are ordered by option string
  ARM: config: sort select statements alphanumerically
  UAPI: (Scripted) Disintegrate arch/arm/include/asm

Fix up fairly conflict in arch/arm/Kconfig (the select re-organization
vs recent addition of GENERIC_KERNEL_EXECVE)
