From 709972b1f6f70535d1fddbe1243a51b90c408a1c Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 31 Aug 2009 11:57:20 -0700 Subject: x86, asm: Make _ASM_EXTABLE() usable from assembly code We have had this convenient macro _ASM_EXTABLE() to generate exception table entry in inline assembly. Make it also usable for pure assembly. Signed-off-by: H.
