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.
