BTW, regarding uaccess plans for the next cycle:
* regset mess (at least the ->get() side)
* killing more compat_alloc_user_space() call sites (_maybe_
all of it, if we are lucky enough; v4l2 is a bitch in that respect,
but I've some ideas on how to deal with that - need to discuss with
* sorting the remaining (harder) parts of i915 out
* kvm/vhost
* fault_in_pages_...() series
That should get rid of almost all __... ones outside of arch/*; might
actually kill copy_in_user() off as well.
* finally lifting stac/clac out of raw_copy_{to,from}_user().
