Patch 2 fixes the existing regression. But if you apply just that patch it
will create a new regression. Patch 1 fixes the place where someone
isn't using the X86_MATCH macros. Just open coding:

   { .vendor = X86_VENDOR_INTEL, .family = 6, .model = INTEL_FAM6_SKYLAKE_X },

so they don't set .flags  Patch 2 changes x86_match_cpu() to just use flags as the
end marker for the array:

    for (m = match; m->flags & X86_CPU_ID_FLAG_ENTRY_VALID; m++) {
