From 0d8559feafbc9dc5a2c17ba42aea7de824b18308 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 20 Apr 2012 12:19:51 -0700 Subject: [PATCH] x86, extable: Remove open-coded exception table entries in arch/x86/lib/copy_user_nocache_64.S Remove open-coded exception table entries in arch/x86/lib/copy_user_nocache_64.S, and replace them with _ASM_EXTABLE() macros; this will allow us to change the format and type of the exception table entries.
