Subject: [PATCH 17/23] x86/oprofile: replace CTRL_SET_*ACTIVE macros
Date: Fri, 12 Jun 2009 14:35:34 +0200 [thread overview]
Message-ID: <1244810140-20595-18-git-send-email-robert.richter@amd.com> (raw)
In-Reply-To: <1244810140-20595-1-git-send-email-robert.richter@amd.com>
The patch replaces all CTRL_SET_*ACTIVE macros. 64 bit MSR functions
and 64 bit counter values are used now. The code uses bit masks from
<asm/intel_arch_perfmon.h>.
