From ab96e798cbd562a53edd802272e49a5100b29efb Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 14 Apr 2009 15:36:29 +0200 Subject: [S390] boot cputime accounting Start the cpu time accounting very early to catch the cpu time spent for the initial kernel setup. To make the output of /proc/uptime match the sum of all cpu accounting values of the boot cpu reset xtime and wall_to_monotonic to sane values based on the TOD clock. The values set by timekeeping_init are off by up to a second.
