  Modified files:
    sys/kern             init_main.c 
  Log:
  When pmap_pinit0() allocates a page for proc0's page directory,
  kernal page table may need to be extended.  But while growing the
  kernel page table (pmap_growkernel()), newly allocated kernel page
  table pages are entered into every process' page directory. For
  proc0, the page directory is not allocated yet, and results in a
  page fault.  Eventually, the machine panics with "lockmgr: not
  holding exclusive lock".
