While the original commit makes it easier to run cpupower from the local build directory, it also leaves the binary with a rather poor rpath of './' in it after it is installed on a system via 'make install'. This is considered bad practice and can cause cpupower to fail in rpmbuild with the following error: ERROR 0004: file '/usr/bin/cpupower' contains an insecure rpath './' in [./] error: Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install) Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install) Developers should be able to use LD_LIBRARY_PATH to achieve the same effect and not introduce rpath into the binary.

In doing so, updated to match January 2015 "Intel(R) 64 and IA-23 Architectures Software Developer's Manual". In the past, turbostat would print package C-state residency columns for all package states supported by the model's architecture, even though a particular SKU may not support them, or they may be disabled by the BIOS. Now turbostat will skip printing colunns if MSRs indicate that they are not enabled. eg. many SKUs don't support PC7, and so that column will no longer be printed.

Update man page to reflect recent changes.

All arithmetic in turbostat using the TSC value is per-processsor, so it does not depend on the TSC values being in sync acrosss processors. Turbostat uses gettimeofday() for the measurement interval rather than using the TSC directly, so that key metric is also immune from variable TSC. Turbostat prints a TSC sanity check column: TSC_MHz = TSC_delta/interval If this column is constant and is close to the processor base frequency, then the TSC is behaving properly. The other key turbostat columns are calculated this way: Avg_Mhz = APERF_delta/interval %Busy = MPERF_delta/TSC_delta Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/interval Tested on Core2 and Core2-Xeon, and so this patch includes a few other changes to remove the assumption that target systems are Nehalem and newer.
