From c0015f91d8414f55d2debfe9984a04b98b48f087 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Thu, 17 Apr 2008 07:46:16 +0200 Subject: [S390] switch sched_clock to store-clock-extended. Add get_clock_xt to read an 8 byte clock value using store clock extended (STCKE) and use get_clock_xt for sched_clock. STCKE should be faster than STCK on newer machines.
