Frederic Weisbecker 3c93ca00ee x86: Add missing might_fault() checks to copy_{to,from}_user() ... On x86-64, copy_[to|from]_user() rely on assembly routines that never call might_fault(), making us missing various lockdep checks. This doesn't apply to __copy_from,to_user() that explicitly handle these calls, neither is it a problem in x86-32 where copy_to,from_user() rely on the "__" prefixed versions that also call might_fault().
