src/sys/arch/x86/x86: cpu.c
Log Message:
Stop panic()ing on a UP system.
The reason for the panic is that the cpu_attach() doesn't run to
completion because it thinks it's run past maxcpus (which in the case
of UP), is 1.
This is because on x86 at least, mi_cpu_attach() is called *before*
configure() (and thus the cpu_match()/cpu_attach() pair). Thus ncpu
has already been incremented by the time MD cpu_attach() is called.
Fix this.
