[PATCH] powerpc: Allow non zero boot cpuids
We currently have a hack to flip the boot cpu and its secondary thread to logical cpuid 0 and 1. This means the logical - physical mapping will differ depending on which cpu is boot cpu. This is most apparent on kexec, where we might kexec on any cpu and therefore change the mapping from boot to boot. The patch below does a first pass early on to work out the logical cpuid of the boot thread. We then fix up some paca structures to match. Ive also removed the boot_cpuid_phys variable for ppc64, to be consistent we use get_hard_smp_processor_id(boot_cpuid) everywhere.
