From d63dcf49cf5ae5605f4d14229e3888e104f294b1 Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Wed, 23 Mar 2016 15:41:59 -0600 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().
