From dcc42f483d6808ba4d04af9da35e7e47b711f6c2 Mon Sep 17 00:00:00 2001 From: Sonny Rao Date: Wed, 2 Aug 2006 00:20:09 -0400 Subject: [PATCH] [POWERPC] fix PMU initialization on pseries lpar We should not be calling power4_enable_pmcs() in pseries_lpar_enable_pmcs(); just doing the hypercall is sufficient. Prior to 2.6.15 we did not call power4_enable_pmcs() for an lpar. power4_enable_pmcs() tries to read the hid0 register which is no longer legal for an lpar in newer Power processors.
