Peter Anvin <hpa@xxxxxxxxx> CommitDate: Tue, 10 Mar 2009 22:33:06 -0700 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().
