From b952741c80790d2dc9f17fac6f15d87d58dea2a1 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Sat, 16 Jun 2012 15:39:34 +0200 Subject: cputime: Generalize CONFIG_VIRT_CPU_ACCOUNTING S390, ia64 and powerpc all define their own version of CONFIG_VIRT_CPU_ACCOUNTING. Generalize the config and its description to a single place to avoid duplication.
