Subject: CPUFREQ: Enable acpi-cpufreq driver for VIA/Centaur CPUs
X-Git-Url: http://git.gnumonks.org/cgi-bin/gitweb.cgi?p=linux-2.6-via.git;a=commitdiff_plain;h=03c869d3e851c585b30d0b1d115546406da2c692

CPUFREQ: Enable acpi-cpufreq driver for VIA/Centaur CPUs

The VIA/Centaur C7, C7-M and Nano CPU's all support ACPI based cpu p-states
using a MSR interface.  The Linux driver just never made use of it, since in
addition to the check for the EST flag it also checked if the vendor is Intel.
