Subject: [PATCH] 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.
