[v3,01/36,V2,01/38] x86/smpboot: Cleanup topology_phys_to_logical_pkg()/die()

Commit Message

Thomas Gleixner May 8, 2023, 7:43 p.m. UTC

From: Thomas Gleixner <[e-mail]>

Make topology_phys_to_logical_pkg_die() static as it's only used in
smpboot.c and fixup the kernel-doc warnings for both functions.
