[PATCH] fix i386 mutex fastpath on FRAME_POINTER && !DEBUG_MUTEXES · 73165b88

Ingo Molnar authored 19 years ago


Call the mutex slowpath more conservatively - e.g.  FRAME_POINTERS can
change the calling convention, in which case a direct branch to the
slowpath becomes illegal.  Bug found by Hugh Dickins.
