From 8e0b842948156e3463879caed12b4ce51bed772e Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 28 Apr 2009 08:19:50 +0000 Subject: [PATCH] sh: setup timers in late_time_init() This patch moves the SuperH timer setup code from time_init() to late_time_init(). Good things about this change: - interrupts: they are enabled at late_time_init() - mm: regular kmalloc() can be used at late_time_init() Together with moving to late_time_init() this patch changes the sh_cmt driver to always allocate with kmalloc(). This simplifies the code a bit and also fixes section mismatches.
