[PATCH] i386: remove redundant might_sleep() in user accessors.
On i386, the user space accessor functions copy_from/to_user() both invoke
might_sleep(), do a quick sanity check, and then pass the work on to their
__copy_from/to_user() counterparts, which again invoke might_sleep().
Given that no actual work happens between these two calls, it is best to
eliminate one of the redundant might_sleep()s.
