The architecture-dependent
-.Nm
+.Nm pmap
module describes how the physical mapping is done between the user-processes
and kernel virtual addresses and the physical addresses of the main memory,
providing machine-dependent translation and access tables that are used
directly or indirectly by the memory-management hardware.
The
-.Nm
+.Nm pmap
layer can be viewed as a big array of mapping entries that are indexed by
virtual address to produce a physical address and flags.
