From 40565b5aedd6d0ca88b7dfd3859d709d2f6f8cf9 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Tue, 15 Nov 2016 03:06:51 +0100 Subject: sched/cputime, powerpc, s390: Make scaled cputime arch specific Only s390 and powerpc have hardware facilities allowing to measure cputimes scaled by frequency. On all other architectures utimescaled/stimescaled are equal to utime/stime (however they are accounted separately). Remove {u,s}timescaled accounting on all architectures except powerpc and s390, where those values are explicitly accounted in the proper places.
