From d12b0e24c56c6fb2398609f26858e5278d688840 Mon Sep 17 00:00:00 2001 From: Torben Hohn <torbenh@gmx.de> Date: Thu, 27 Jan 2011 16:00:27 +0100 Subject: [PATCH] xtensa: Switch do_timer() to xtime_update() xtime_update() takes the xtime_lock itself. set_linux_timer() does not need to be protected by xtime_lock.
