DESCRIPTION
Thepmap_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.
