From 9451c79bc39e610882bdd12370f01af5004a3c4f Mon Sep 17 00:00:00 2001 From: Ilie Halip Date: Fri, 20 Sep 2019 18:39:51 +0300 Subject: powerpc/pmac/smp: Avoid unused-variable warnings When building with ppc64_defconfig, the compiler reports that these 2 variables are not used: warning: unused variable 'core99_l2_cache' [-Wunused-variable] warning: unused variable 'core99_l3_cache' [-Wunused-variable] They are only used when CONFIG_PPC64 is not defined. Move them into a section which does the same macro check.
