[PATCH] x86_64: Don't do syscall exit tracing twice
int_ret_from_syscall already does syscall exit tracing, so no need to do it again in the caller. This caused problems for UML and some other special programs doing syscall interception. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
