Hi,

this came about after Nadav asked about static_cpu_has() and when it
should be used. The resulting converts a bunch of slow-paths to use
the plain boot_cpu_has() tester which is straight-forward and doesn't
require to be patched in by alternatives, leaving static_cpu_has() only
to the fast paths, where it should be used anyway.

Thx.

Borislav Petkov (5):
x86/asm: Clarify static_cpu_has()'s intended use
x86: Convert some slow-path static_cpu_has() callers to boot_cpu_has()
x86/kvm: Convert some slow-path static_cpu_has() callers to
boot_cpu_has()
x86/mm: Convert some slow-path static_cpu_has() callers to
boot_cpu_has()
drivers/cpufreq: Convert some slow-path static_cpu_has() callers to
boot_cpu_has()
