Andreas Herrmann 36bf50d769 x86, microcode, AMD: Fix broken ucode patch size check ... This issue was recently observed on an AMD C-50 CPU where a patch of maximum size was applied. Commit be62adb492 ("x86, microcode, AMD: Simplify ucode verification") added current_size in get_matching_microcode(). This is calculated as size of the ucode patch + 8 (ie. size of the header). Later this is compared against the maximum possible ucode patch size for a CPU family. And of course this fails if the patch has already maximum size.
