2014-10-08	x86: Improve cmpxchg16b_emu.S	Jan Beulich	1	-19/+13
	- don't include unneeded headers - don't open-code PER_CPU_VAR() - drop redundant entry point label - complete unwind annotations - use .L prefix on local label to not clutter the symbol table Signed-off-by: Jan Beulich <jbeulich@suse.com> Link: http://lkml.kernel.org/r/542290BC020000780003807D@mail.emea.novell.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-28	percpu: Omit segment prefix in the UP case for cmpxchg_double	Christoph Lameter	1	-4/+10
	Omit the segment prefix in the UP case. GS is not used then and we will generate segfaults if cmpxchg16b is used otherwise. Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-02-28	percpu, x86: Add arch-specific this_cpu_cmpxchg_double() support	Christoph Lameter	1	-0/+59
	Support this_cpu_cmpxchg_double() using the cmpxchg16b and cmpxchg8b instructions. -tj: s/percpu_cmpxchg16b/percpu_cmpxchg16b_double/ for consistency and other cosmetic changes. Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Tejun Heo <tj@kernel.org>
