From 5490fa96735ce0e2af270c0868987d644b9a38ec Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Wed, 11 Mar 2009 10:14:26 +0900 Subject: x86, mce: use round_jiffies() instead round_jiffies_relative() Impact: saving power _very_ little round_jiffies() round up absolute jiffies to full second. round_jiffies_relative() round up relative jiffies to full second. The "t->expires" is absolute jiffies. Then, round_jiffies() should be used instead round_jiffies_relative(). Signed-off-by: KOSAKI Motohiro Cc: Andi Kleen Cc: H. Peter Anvin Signed-off-by: H.
