From 03f07876df2565321871a2dbf33c5c737df185df Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 29 Jan 2009 11:21:38 +0900 Subject: sh: Fix up spurious syscall restarting. The T-bit manipulation for syscall error checking had the side effect of spuriously returning ERESTART* errno values over EINTR. So, we simplify the error checking a bit and leave the T-bit alone.
