Just filter out P5 and earlier. The code already does that for CPUs

Actually, an alternative - more practical albeit not very accurate
More practical ? Hmm - the MSRs don't exist for< P5
solution would be to check for which families Intel delivers microcode
and do the cut off there with a comment as to why you do it like
that.void
You mean return !intel so this function will never be called.
__init load_ucode_bsp(void)
{
int vendor = x86_vendor();
if (vendor == X86_VENDOR_INTEL)
load_ucode_intel_bsp();
}
Ah yes. That would work and be less code.
We should do it that way.
Do you think you can have a patch for me in the next few hours?
Sure.
I'm in Ireland (sleeping @ 00:15 on a Friday night sadly).
Give me ~ 40 minutes
