[PATCH v3 0/2] tools/hvmloader: Decouple APIC IDs from vCPU IDs

[Alejandro Vallejo <alejandro.vallejo@xxxxxxxxx>]

v2->v3:
  * Moved "extern uint32_t *cpu_to_apicid;" to patch1

v2: 
https://lore.kernel.org/xen-devel/20250204144542.7399-1-alejandro.vallejo@xxxxxxxxx/T/#t
v1->v2:
  * Dropped patch to skip writing the MP Tables if apicid >= 255

v1:

The hypervisor, hvmloader and the toolstack currently engage in a shared
assumption that for every vCPU apicid == 2 * vcpuid. This series removes such
assumption from hvmloader, by making it read the APIC ID of each vCPU and
storing it for later use.

  tools/hvmloader: Retrieve APIC IDs from the APs themselves
  tools/hvmloader: Replace LAPIC_ID() with cpu_to_apicid[]
