Subject: [PATCH 28/28] perf pmu: Move *_cpuid_str() weak functions to header.c

From: Kan Liang <kan.liang@...ux.intel.com>

The weak functions, strcmp_cpuid_str() and get_cpuid_str(), are defined
in pmu.c.

Most of the cpuid related functions, including *_cpuid_str()'s
declaration and platform specific definition, are in header.c/h.

To make the declaration and definition of all cpuid related functions in
a consistent place, move the weak functions to header.c.

There is no functional change.
