From 67e87d43b794a8886b5d075b3e0fdd0c615a595f Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 29 Mar 2019 19:52:59 +0100 Subject: x86: Convert some slow-path static_cpu_has() callers to boot_cpu_has() Using static_cpu_has() is pointless on those paths, convert them to the boot_cpu_has() variant. No functional changes.
