[CPUFREQ] p4-clockmod: fix support for Core
Support for Core CPUs was broken in two ways in speedstep-lib: for x86_64, we missed a MSR definition; for both x86_64 and i386, the FSB calculation was wrong by four (it's a quad-pumped bus). Also increase the accuracy of the calculation. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Dave Jones <davej@redhat.com>
