x86/cpu/intel: Replace PAT erratum model/family magic numbers with symbolic IFM references

There's an erratum that prevents the PAT from working correctly:

x86/cpu/intel: Replace PAT erratum model/family magic numbers with symbolic IFM references

There's an erratum that prevents the PAT from working correctly:

https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/pentium-dual-core-specification-update.pdf
# Document 316515 Version 010

The kernel currently disables PAT support on those CPUs, but it
does it with some magic numbers.

Replace the magic numbers with the new "IFM" macros.

Make the check refer to the last affected CPU (INTEL_CORE_YONAH)
rather than the first fixed one. This makes it easier to find the
documentation of the erratum since Intel documents where it is
broken and not where it is fixed.

I don't think the Pentium Pro (or Pentium II) is actually affected.
But the old check included them, so it can't hurt to keep doing the
same. I'm also not completely sure about the "Pentium M" CPUs
(models 0x9 and 0xd). But, again, they were included in in the
old checks and were close Pentium III derivatives, so are likely
affected.

While we're at it, revise the comment referring to the erratum name
and making sure it is a quote of the language from the actual errata
doc. That should make it easier to find in the future when the URL
inevitably changes.

Why bother with this in the first place? It actually gets rid of one
of the very few remaining direct references to c->x86{,_model}.

No change in functionality intended.

Merge tag 'x86-cpu-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cpu updates from Ingo Molnar:

- Rework the x86 CPU vendor/family/model code: introduce the 'VFM'
value that is an 8+8+8 bit concatenation of the vendor/family/model
value, and add macros that work on VFM values. This simplifies the
addition of new Intel models & families, and simplifies existing
enumeration & quirk code.

- Add support for the AMD 0x80000026 leaf, to better parse topology
information

- Optimize the NUMA allocation layout of more per-CPU data structures

- Improve the workaround for AMD erratum 1386

- Clear TME from /proc/cpuinfo as well, when disabled by the firmware

- Improve x86 self-tests

- Extend the mce_record tracepoint with the ::ppin and ::microcode fields

- Implement recovery for MCE errors in TDX/SEAM non-root mode

- Misc cleanups and fixes
