From: Ingo Molnar Date: Tue, 9 Dec 2008 10:40:46 +0000 (+0100) Subject: perfcounters, x86: simplify disable/enable of counters X-Git-Tag: v2.6.31-rc1~383^2~585 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7e2ae34749edf19e76e594b9c4b2cdde1066afc5;p=pandora-kernel.git perfcounters, x86: simplify disable/enable of counters Impact: fix spurious missed counter wakeups In the case of NMI events, close a race window that can occur if an NMI hits counter code that temporarily disables+enables a counter, and the NMI leaks into the disabled section.
