From c8128cceb4f4b02c53096cb173628184c7e9bc36 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Thu, 11 Sep 2014 14:15:11 -0700 Subject: x86: Axe the lightly-used cpu_has_pae cpu_has_pae is only referenced in one place: the X86_32 kexec code (in a file not even built on 64-bit). It hardly warrants its own macro, or the trouble we go to ensuring that it can't be called in X86_64 code. Axe the macro and replace it with a direct cpu feature check.
