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 mchehab) * 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().
