Subject: [PATCH] x86/mm/pat: Replace cpu_has_pat with boot_cpu_has()
Borislav Petkov suggested:
> Please use on init paths boot_cpu_has(X86_FEATURE_PAT) and on fast
> paths static_cpu_has(X86_FEATURE_PAT). No more of that cpu_has_XXX
> ugliness.
Replace the use of cpu_has_pat on init paths with boot_cpu_has().
