From 00df111e7eb505558c54f23861e9341e56dd5fb0 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 19 May 2012 00:29:22 -0400 Subject: parisc: fix double restarts Don't bother restoring r28 on syscall restarts; it's clobbered by syscall anyway. Reuse (now unused) ->orig_r28 as "no restarts allowed" flag.
