From 3eb3e7dd53a83cbe6e7b95aa87d2c5dc861233a6 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Mon, 11 Feb 2013 14:40:55 +0530 Subject: [PATCH] ARC: Fix pt_orig_r8 access Syscall restarting fixes made pt_regs->orig_r8 a short word, which was not reflected in the assembler code - thus could potentially break gdb debugging.
