sys/alpha/alpha mp_machdep.c
Log:
Add a new variable mp_maxid. This is used so that per cpu datastructures may
be allocated as arrays indexed by the cpu id. Previously the only reliable
way to know the max cpu id was through MAXCPU. mp_ncpus isn't useful here
because cpu ids may be sparsely mapped, although x86 and alpha do not do this.
Also, call cpu_mp_probe much earlier so the max cpu id is known before the VM
starts up. This is intended to help support per cpu queues for the new
allocator, but may be useful elsewhere.
