This patch series provides fixes around AP startup and sorting:
- The CPUID_EXTENDED_TOPOLOGY CPUID leaf takes a sub-leaf as input. The
current SEV-SNP support is attempting to retrieve the this leaf with
sub-leaf 0, but is calling AsmCpuid(), which does not clear ECX before
invoking the CPUID instruction. Therefore, because of the calling
convention, the leaf value becomes the sub-leaf value and ends up
returning incorrect information. Change the call from AsmCpuid() to
AsmCpuidEx().
- When sorting the CPUs by APIC ID, the VMSA associated with the vCPU
should follow the APIC ID. Update the sorting code to swap the VMSA
pointer during the sort.

Eric/Ray/Rahul,
Have you had a chance to review this series? These bug fixes would be good
to get in for the next/latest release...
Eric/Ray/Rahul,
Any feedback? If not, can you Ack them so they can be merged... they
already missed the edk2-stable202311 tag.
Thanks,
Tom
Thanks,
Tom
