So it's 'uaccess-cleanups', plural, in case someone copy & pasted
this URI verbatim instead of using the branch name from your
earlier mail. :-)

All the x86 cleanups look good to me in principle, and a quick
test-build & boot shows no problems (both on 64-bit and 32-bit),
but regular testing doesn't fully excercise the exception paths
of these changes, so YMMV.

( BTW., there's a new dependency introduced by this series,
  if an architecture gets rid of __get_user(), then it must
  define arch_get_kernel_nofault(), otherwise it will gain
  new uses of __get_user()/__put_user() via the generic implementations
  of __get_kernel_nofault() and __put_kernel_nofault(). No big deal
  I suppose. )

Thanks,
