From d7abc0fa997972ddb6d3c403e03a6eefda0c0881 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 20 Apr 2012 12:19:50 -0700 Subject: x86, extable: Remove open-coded exception table entries in arch/x86/kernel/entry_64.S Remove open-coded exception table entries in arch/x86/kernel/entry_64.S, and replace them with _ASM_EXTABLE() macros; this will allow us to change the format and type of the exception table entries.
