NAME

       pmap_init, pmap_init2 — initialize the pmap subsystem

SYNOPSIS

       #include <sys/param.h>
       #include <vm/vm.h>
       #include <vm/pmap.h>

       void
       pmap_init(void);

       void
       pmap_init2(void);

DESCRIPTION

       The  pmap_init()  function initializes the pmap(9) sub-system.  It is called during system initialization
       by vm_init(), to initialize any structures that the pmap_init  system  needs  in  order  to  map  between
       physical and virtual memory.

       The  pmap_init2()  function  initializes  a  zone  for  the PV entries.  These are used to implement page
       sharing at the physical level.  A high water mark is set so that the system can  recover  from  excessive
       numbers of PV entries.
