PMAP_INIT(9)		 BSD Kernel Developer's	Manual		  PMAP_INIT(9)

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	physi-
     cal 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.
