Date: Sat, 22 Jan 2011 00:07:00 +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 14/18] mn10300: switch do_timer() to xtimer_update() xtimer_update() properly takes the xtime_lock. mn10300_last_tsc is only accessed from this function.
