Date: Sun, 25 Nov 2007 13:59:51 -0800 (PST) From: Roland McGrath <roland@...hat.com> To: Andrew Morton <akpm@...ux-foundation.org>, Linus Torvalds <torvalds@...ux-foundation.org> Cc: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...e.hu>, "H. Peter Anvin" <hpa@...or.com> Subject: [PATCH 06/27] x86: single_step segment macros This cleans up the single-step code to use the asm/segment.h macros for segment selector magic bits, rather than its own constant.
