Interrupts are disabled if Giant is busy in vm_page_zero_idle, thus
the idle proc calls mi_switch with interrupts disabled and the process
being scheduled starts running with interrupts disabled.

I suggest removing the asm statement from vm_page_zero_idle as a first
stage in rewriting vm_page_zero_idle.
