Hmm, CPUs really should just not show up when they are disabled - maybe, but that means fudging with mp_ncpus. - Fix boot_cpu_id to be a logical FreeBSD cpuid that is the BSP on all archs - Maybe hardcode FreeBSD cpuid 0 as BSP instead - Change alpha to use logical FreeBSD cpuid's rather than mapping 1:1 to physical IDs -- Revert bde's changes to the interrupt storm code. +- Split critical sections from spinlocks some, create spinlock_enter/exit() + MD API to replace cpu_critical_*.
