Comment:
CC'ing korli: I've always wondered if we should not be using set/clear_ac
but always go through user_memcpy (I am pretty sure PulkoMandy implied we
would have to for SPARC, and possibly other architectures anyway?). It
seems strange that the user_thread pointer is incorrect here, but
user_memcpy should solve the problem either way.
It also looks like _user_unblock_thread does not actually call
thread_check_permissions, either. Wonder how I missed that one.
