From: Chen Yucong Date: Thu, 2 Oct 2014 15:20:12 +0000 (+0800) Subject: x86, MCE, AMD: Move invariant code out from loop body X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=69b957583580bf40624553c64d802fefb54199cb;p=linux-beck.git x86, MCE, AMD: Move invariant code out from loop body Assigning to mce_threshold_vector is loop-invariant code in mce_amd_feature_init(). So do it only once, out of loop body.
