From 81a3843f97cff5fef7b6006fcd2d015d3c4b569f Mon Sep 17 00:00:00 2001 From: Tony Breeds Date: Tue, 4 Dec 2007 16:51:44 +1100 Subject: [POWERPC] Fix hardware IRQ time accounting problem. The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (sched: restore deterministic CPU accounting on powerpc), unconditionally calls update_process_tick() in system context. In the deterministic accounting case this is the correct thing to do. However, in the non-deterministic accounting case we need to not do this, since doing this results in the time accounted as hardware irq time being artificially elevated. Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING' checks in time.h into one for neatness.
