Subject: [PATCH 3/8] tools/power x86_energy_perf_policy: rename get_msr() and put_msr() with intel prefix
From: Perry Yuan <Perry.Yuan@....com>
Rename the get_msr() and put_msr() function with Intel prefix,that will
better help to differentiate with other processor msr operation.
No functional impact.
