kernel - Do not use shared tokens for kernel_map
* This primarily handles a case where i386 systems can deadlock on a
shared token -> exclusive token sequence during a page fault, because
the i386 pmap code uses kernel_object to manage page table pages.
x86-64 page fault code does not but for now just make the change globally.
* Should not effect performance
* Change the default for vm_
* Change the default for vm.shared_fault back to 1.
