Date: Sat, 22 Jan 2011 00:07:03 +0100 From: Torben Hohn <torbenh@....de> To: linux-kernel@...r.kernel.org Cc: tglx@...utronix.de, johnstul@...ibm.com, hch@...radead.org, yong.zhang0@...il.com, Torben Hohn <torbenh@....de> Subject: [PATCH 17/18] xtensa: switch do_timer() to xtime_update() xtime_update() takes the xtime_lock itself. i dont believe that set_linux_timer() needs to be protected by a lock.
