Subject: [PATCH hyperv-next 0/2] arch/x86, x86/hyperv: Few fixes for the AP startup

This patchset combines two patches that depend on each other and were not applying
cleanly:
  1. Fix APIC ID and VP index confusion in hv_snp_boot_ap():
    https://lore.kernel.org/linux-hyperv/20250430204720.108962-1-romank@linux.microsoft.com/
  2. Provide the CPU number in the wakeup AP callback:
    https://lore.kernel.org/linux-hyperv/20250430204720.108962-1-romank@linux.microsoft.com/

I rebased the patches on top of the latest hyperv-next tree and updated the second patch
that broke the linux-next build. That fix that, I made one non-functional change:
updated the signature of numachip_wakeup_secondary() to match the parameter list of
wakeup_secondary_cpu().
