Message-ID: <20110127150027.23248.61798.stgit@localhost> Date: Thu, 27 Jan 2011 16:00:27 +0100 From: Torben Hohn <torbenh@....de> To: LKML <linux-kernel@...r.kernel.org> Cc: Chris Zankel <chris@...kel.net>, Peter Zijlstra <peterz@...radead.org>, johnstul@...ibm.com, hch@...radead.org, yong.zhang0@...il.com, Thomas Gleixner <tglx@...utronix.de> Subject: [PATCH v2 19/20] xtensa: switch do_timer() to xtime_update() xtime_update() takes the xtime_lock itself. set_linux_timer() does not need to be protected by a lock.
