[Qemu-devel] [PATCH v3 03/10] x86: Extend validity of cpu_is_bsp


From: Jan Kiszka
Subject: [Qemu-devel] [PATCH v3 03/10] x86: Extend validity of cpu_is_bsp
Date: Wed, 24 Feb 2010 15:17:51 +0100

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