The Family model check to read the processor flag MSR is misleading and
potentially incorrect. It doesn't consider Family while comparing the
model number. The original check did have a Family number but it got
lost/moved during refactoring.
intel_collect_cpu_info() is called through multiple paths such as early
initialization, CPU hotplug as well as IFS image load. Some of these
flows would be error prone due to the ambiguous check.
Correct the processor flag scan check to use a Family number and update
it to a VFM based one to make it more readable.

get_this_hybrid_cpu_type() misses a case when cpu-type is populated
regardless of X86_FEATURE_HYBRID_CPU. This is particularly true for hybrid
variants that have P or E cores fused off.
Instead use the cpu-type cached in struct x86_topology, as it does not rely
on hybrid feature to enumerate cpu-type. This can also help avoid the
model-specific fixup get_hybrid_cpu_type(). Also replace the
get_this_hybrid_cpu_native_id() with its cached value in struct
x86_topology.
While at it, remove enum hybrid_cpu_type as it serves no purpose when we
have the exact cpu-types defined in enum intel_cpu_type. Also rename
atom_native_id to intel_native_id and move it to intel-family.h where
intel_cpu_type lives.

Sometimes it is required to take actions based on if a CPU is a performance or
efficiency core. As an example, intel_pstate driver uses the Intel core-type
to determine CPU scaling. Also, some CPU vulnerabilities only affect
a specific CPU type, like RFDS only affects Intel Atom. Hybrid systems that
have variants P+E, P-only(Core) and E-only(Atom), it is not straightforward to
identify which variant is affected by a type specific vulnerability.
Such processors do have CPUID field that can uniquely identify them. Like,
P+E, P-only and E-only enumerates CPUID.1A.CORE_TYPE identification, while P+E
additionally enumerates CPUID.7.HYBRID. Based on this information, it is
possible for boot CPU to identify if a system has mixed CPU types.
Add a new field hw_cpu_type to struct cpuinfo_topology that stores the
hardware specific CPU type. This saves the overhead of IPIs to get the CPU
type of a different CPU. CPU type is populated early in the boot process,
before vulnerabilities are enumerated.

x86/cpu: Add two Intel CPU model numbers
x86/tdx: Fix "in-kernel MMIO" check
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.

Note1: Model 0xB7 already claimed the "no suffix" #define for a regular
client part, so add (yet another) suffix "S" to distinguish this new
part from the earlier one.
Note2: the RAPTORLAKE* and ALDERLAKE* processors are very similar from a
software enabling point of view. There are no known features that have
model-specific enabling and also differ between the two. In other words,
every single place that list *one* or more RAPTORLAKE* or ALDERLAKE*
processors should list all of them.
Note3: This is being merged before there is an in-tree user. Merging
this provides an "anchor" so that the different folks can update their

Finding all places which build x86_cpu_id match tables is tedious and the
logic is hidden in lots of differently named macro wrappers.
Most of these initializer macros use plain C89 initializers which rely on
the ordering of the struct members. So new members could only be added at
the end of the struct, but that's ugly as hell and C99 initializers are
really the right thing to use.
Provide a set of macros which:
- Have a proper naming scheme, starting with X86_MATCH_
- Use C99 initializers
The set of provided macros are all subsets of the base macro
X86_MATCH_VENDOR_FAM_MODEL_FEATURE()
which allows to supply all possible selection criteria:
vendor, family, model, feature
The other macros shorten this to avoid typing all arguments when they are
not needed and would require one of the _ANY constants. They have been
created due to the requirements of the existing usage sites.
Also add a few model constants for Centaur CPUs and QUARK.

Currently the big core client models either have:
- no OPTDIFF
- _CORE
- _DESKTOP
Make it uniformly: 'no OPTDIFF'.
for i in `git grep -l "\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*_\(CORE\|DESKTOP\)"`
do
sed -i -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*\)_\(CORE\|DESKTOP\)/\1/g' ${i}
done
