Andy Lutomirski 72f924783b x86/entry, locking/lockdep: Move lockdep_sys_exit() to prepare_exit_to_usermode() 
Rather than worrying about exactly where LOCKDEP_SYS_EXIT should
go in the asm code, add it to prepare_exit_from_usermode() and
remove all of the asm calls that are followed by
prepare_exit_to_usermode().

LOCKDEP_SYS_EXIT now appears only in the syscall fast paths.
