Modified Files:
        syssrc/sys/vm: vm_map.h

Log Message:
Keep interrupt-safe maps on an additional queue.  In uvm_fault(), if we're
looking up a kernel address, check to see if the address is on this
"interrupt-safe" list.  If so, return failure immediately.  This prevents
a locking screw if a page fault is taken on an interrupt-safe map in or
out of interrupt context.
