this wouldnt build with certain configs:

arch/x86/kernel/smpboot.c: In function 'do_boot_cpu':
arch/x86/kernel/smpboot.c:897: error: 'phys_apicid' undeclared (first use in this function)
arch/x86/kernel/smpboot.c:897: error: (Each undeclared identifier is reported only once
arch/x86/kernel/smpboot.c:897: error: for each function it appears in.)
include/asm/io_32.h: In function 'memcpy_fromio':

because phys_apicid is not available in the !WAKE_SECONDARY_VIA_INIT 
case. Changed it to boot_cpu_physical_apicid - that should be good 
enough.
