b55e164669 page_fault_process_memory_range: Disable COW for VM region with zeroobj 
This fixes ostest-mem_limits.001 which tries to anonymous-mmap 95% of
total memory. It reports a failure because:
(1) McKernel tries to allocate physically contiguous area and
    fails
(2) It turns on demand-paging
(3) It tries to obtain a page from zeroobj and fails
(4) It allocates a new page
(5) It performs COW on the page, which is unnecessary

This fixes ostest-mem_limits.005 which tries to move brk by 95% of

physically contiguous area and fails.
