Subject: [PATCH] perf_events: remove bogus Intel Core constraint on ITLB_MISS_RETIRED
Date: Thu, 11 Mar 2010 12:59:28 -0800	[thread overview]
Message-ID: <1268341168-19705-1-git-send-email-eranian@google.com> (raw)

Contrary to what Vol3b section 30.4.3 leads to believe, there is
no constraint on ITLB_MISS_RETIRED on Intel Core-based CPU, so
remove it.
