Subject: x86/amd: Move amd_get_highest_perf() from amd.c to cppc.c
|
|
|
|
To prepare to let amd_get_highest_perf() detect preferred cores
|
|
it will require CPPC functions. Move amd_get_highest_perf() to
|
|
cppc.c to prepare for 'preferred core detection' rework.
|
|
|
|
No functional changes intended.
