score: fix bogus restarts on sigreturn()
we *really* don't want to have restart logics hit when we are returning from sigreturn() - random replacement of %r4 with -4 just because a signal had been noticed from timer interrupt that came when %r4 happened to contain -514 is not nice at all. Signed-off-by: Al Viro <>
