I am working on vm86 bios call crash bug for CURRENT and have already a 
working patch on my machine, I have tested the patch under heavy loaded, 
seems be very stable. in the patch, I replace current thread pcb pointer to 
a temporary pcb, the pcb of course is not created by pmap, I am not very
certain whether it is safe, any help will be appreciated.
