From 948b1bb89a44561560531394c18da4a99215f772 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Mon, 29 Mar 2010 18:36:50 +0200 Subject: perf, x86: Undo some some *_counter* -> *_event* renames The big rename: cdd6c48 perf: Do the big rename: Performance Counters -> Performance Events accidentally renamed some members of stucts that were named after registers in the spec. To avoid confusion this patch reverts some changes. The related specs are MSR descriptions in AMD's BKDGs and the ARCHITECTURAL PERFORMANCE MONITORING section in the Intel 64 and IA-32 Architectures Software Developer's Manuals.
