From da28c597996a964a195529595c37f7aacd6dad09 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 14 Jun 2010 16:02:47 +0900 Subject: [PATCH] sh: split out ptrace header for _32/_64 variants. asm/ptrace.h is getting a bit messy, with the _32/_64-specific changes being fairly insular. This splits out the header accordingly.
