  Modified files:
    sys/vm               vm_page.h 
  Log:
  Move the cow field between wire_count and hold_count. This is the
  position that is 64-bit aligned and makes sure that the valid and
  dirty fields are also 64-bit aligned. This means that if PAGE_SIZE
  is 32K, the size of the vm_page structure is only increased by 8
  bytes instead of 16 bytes. More importantly, the vm_page structure
  is either 120 or 128 bytes on ia64. These are "interesting" sizes.
