        src/sys/arch/i386/i386: bioscall.S

Log Message:
i386/bioscall: Disable preemption while we load the kernel pmap.

Fixes crash on boot in new KASSERT(kpreempt_disabled()) in
cpu_load_pmap.

We could do KASSERT(kpreempt_disabled() || cold), but I don't know if
bioscall is ever reachable after warm boot; this way is safer.

XXX Would be nice if bioscall were a C function, not asm -- I don't
see any reason why we need it to be asm?
