Previously these processors all showed up as family 0xf. See the document https://support.amd.com/TechDocs/56255_OSRR.pdf section CPUID_Fn00000001_EAX for how to calculate the family from the BaseFamily and ExtFamily values.

The switch that conditionally sets CPUPOWER_CAP_HAS_TURBO_RATIO and CPUPOWER_CAP_IS_SNB flags is missing a break, so all cores get both flags set and an assumed base clock of 100 MHz for turbo values.

This patch changes the Makefile to use $CURDIR instead, which GNU make guarantees to set and update (i.e. when using "make -C ...") and also adds support for the O= option (see "make help" in your root of your kernel source tree for more details).
