commit c36eb0a13923c9c97cf460faf5189ba7cac39d72 Author: Aaron Durbin adurbin@chromium.org Date: Mon Mar 7 16:23:47 2016 -0600
x86 chipsets: utilize x86_setup_mtrrs_with_detect()
For all the chipsets which were performing the following sequence: x86_setup_fixed_mtrrs(); x86_setup_var_mtrrs(cpuid_eax(0x80000008) & 0xff, 2);
Replace that with x86_setup_mtrrs_with_detect() since it is equivalent.
