From af445f45ed64fb0276c0f29bf30d7586e0b8d5f2 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 30 Apr 2012 23:37:41 -0400 Subject: 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.
