DESCRIPTION

The pmap_init() function initializes the pmap(9) sub-system.

It is
called during system initialization by vm_init(), to ini

tialize 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 en

tries. 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.
