Remove the family check for accessing the MSR_AMD_HWCR MSR and replace it with a cpupower cap flag. This update also allows for the removal of the local cpupower_cpu_info variable in cpufreq_has_boost_support() since we no longer need it to check the family.

The cpupower package consists of the following elements: requirements ------------ On x86 pciutils is needed at runtime (-lpci). For compilation pciutils-devel (pci/pci.h) and a gcc version providing cpuid.h is needed. For both it's not explicitly checked for (yet). libcpupower ---------- "libcpupower" is a library which offers a unified access method for userspace tools and programs to the cpufreq core and drivers in the Linux kernel. This allows for code reduction in userspace tools, a clean implementation of the interaction to the cpufreq core, and support for both the sysfs and proc interfaces [depending on configuration, see below]. compilation and installation ---------------------------- make su make install should suffice on most systems. It builds libcpupower to put in /usr/lib; cpupower, cpufreq-bench_plot.sh to put in /usr/bin; and cpufreq-bench to put in /usr/sbin. If you want to set up the paths differently and/or want to configure the package to your specific needs, you need to open "Makefile" with an editor of your choice and edit the block marked CONFIGURATION. THANKS ------ Many thanks to Mattia Dongili who wrote the autotoolization and libtoolization, the manpages and the italian language file for cpupower; to Dave Jones for his feedback and his dump_psb tool; to Bruno Ducrot for his powernow-k8-decode and intel_gsic tools as well as the french language file; and to various others commenting on the previous (pre-)releases of cpupower.
