From 002ec58eb57bac2380f0ed5a4e88121b4bdb32ec Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sat, 7 Jan 2006 00:49:49 +1100 Subject: [PATCH] ppc64: fix time syscall ppc64 has its own version of sys_time. It looks pretty scary, touching a whole bunch of variables without any locking or memory ordering. In fact, a recent bugreport has shown it can actually go backwards. Time to remove it and just use the generic sys_time, which is implemented on top of do_gettimeofday.
