Message-Id: <20071125220859.28B7726F8DE@magilla.localdomain> Date: Sun, 25 Nov 2007 14:08:59 -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 27/27] x86: PTRACE_SINGLEBLOCK This adds the PTRACE_SINGLEBLOCK request on x86, matching the ia64 feature. The implementation comes from the generic ptrace code and relies on the low-level machine support provided by arch_has_block_step() et al.
