From e41e0fc61ae776b9235380fe9570af31ea7bbc86 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 19 Apr 2011 13:06:06 +0200 Subject: [PATCH] x86: Allow multiple cpu feature matches of lookup_feature kvmclock is represented by two feature bits. Therefore, lookup_feature needs to continue its search even after the first match. Enhance it accordingly and switch to a bool return type at this chance.
