[PATCH 1/2] X86: fix cpufreq _psd HW_ALL coordination bug
X86: Fix cpufreq _psd HW_ALL coordination bug
Currently xen cpufreq has a bug when handleing _psd HW_ALL,
which will result in system broken when _psd HW_ALL.
This patch fix this bug by handling _psd HW_ALL in same way as
SW_ALL coordiantion, for the seek of safety.

[PATCH] AMD, powernow: Update P-state directly when _PSD's CoordType is DOMAIN_COORD_TYPE_HW_ALL
# HG changeset patch
# User Boris Ostrovsky <boris.ostrovsky@amd.com>
# Date 1345135101 -7200
# Node ID 85190245a94d9945b7656c971ba36f7d1eff5c19

AMD, powernow: Update P-state directly when _PSD''s CoordType is DOMAIN_COORD_TYPE_HW_ALL
When _PSD''s CoordType is DOMAIN_COORD_TYPE_HW_ALL (i.e. shared_type is
CPUFREQ_SHARED_TYPE_HW) which most often is the case on servers, there is no
reason to go into on_selected_cpus() code, we call call transition_pstate()
directly.
