| |
From: Andreas Herrmann <andreas.herrmann3@amd.com>
amd_fixup_dcm() already checks for existence of a CPUID flag, so there is no point in further restricting this function to run only on specific CPUs.
In particular this prevents amd_fixup_dcm() to be executed on future AMD CPU families which might also be available as multi-node processors. (IMHO this is good reason to tag this patch for stable trees.)
