`ncpu != 0' doesn't make much sense when deciding what CP info to print.

CLKF_INTR() needs to have a MULTIPROCESSOR version.

We use MULTIPROCESSOR explicitly here, so pull in "opt_multiprocessor.h".

Make `_cpcb' (pointer to current user area) a per-CPU variable.

This cpuinfo field is initialized here in locore before calling bootstrap(),
since it must be valid before entering the window overflow/underflow handlers.
Fix miscalculation in the MULTIPROCESSOR version of INTR_SETUP().

Allocate a private PCB, kernel stack and interrupt stack for each processor.
...
As a result, the stack setup code in locore.s changes slightly in
the MULTIPROCESSOR case. Also, make the stack redzone barrier (for
debugging only) a per-CPU entity.
