[PATCH 01/14] x86/cpu: Move intel-family to arch-independent headers

Iwona Winiarska
2021-07-12T22:07:34Z

Baseboard management controllers (BMC) often run Linux but are usually
implemented with non-X86 processors. They can use PECI to access package
config space (PCS) registers on the host CPU and since some information,
e.g. figuring out the core count, can be obtained using different
registers on different CPU generations, they need to decode the family
and model.

Move the data from arch/x86/include/asm/intel-family.h into a new file
include/linux/x86/intel-family.h so that it can be used by other
architectures.

To limit tree-wide changes and help people that were expecting
intel-family defines in arch/x86 to find it more easily without going
through git history, we're not removing the original header
completely, we're keeping it as a "stub" that includes the new one.
If there is a consensus that the tree-wide option is better,
we can choose this approach.
