Series [v2,1/9] x86/cpu/topology: Add CPU type to struct cpuinfo_topology | expand

Commit Message

Pawan Gupta June 27, 2024, 8:44 p.m. UTC 
To add cpu-type to the existing CPU matching infrastructure, the base macro
X86_MATCH_VENDOR_FAM_MODEL_STEPPINGS_FEATURE need to append _CPU_TYPE. This
makes an already long name longer, and somewhat incomprehensible.

To avoid this, rename the base macro to X86_MATCH_CPU. The macro name
doesn't need to explicitly tell everything that it matches. The arguments
to the macro already hints what it matches.

For consistency, use this base macro to define X86_MATCH_VFM and friends.
