[Qemu-devel] [PATCH 6/6] x86: Extend validity of bsp_to_cpu

[Marcelo Tosatti]

From: Jan Kiszka <address@hidden>

As we hard-wire the BSP to CPU 0 anyway and cpuid_apic_id equals
cpu_index, bsp_to_cpu can also be based on the latter directly. This
will help an early user of it: KVM while initializing mp_state.
