+.Nm kmem
+.Nd memory files
+.Sh DESCRIPTION
+The special file
+.Nm /dev/mem
+is an interface to the physical memory of the computer.
+Byte offsets in this file are interpreted as physical memory addresses.
+Reading and writing this file is equivalent to reading and writing
+memory itself.
+Only offsets within the bounds of
+.Nm /dev/mem
+are allowed.
+.Pp
+Kernel virtual memory is accessed through the interface
+.Nm /dev/kmem
+in the same manner as
+.Nm /dev/mem .
+Only kernel virtual addresses that are currently mapped to memory are allowed.
+.Pp
+On
+.Tn Acorn RiscPC, A7000(+) and RC7500 systems
+the
+.Tn I/O
+memory space (podule space and SuperIO) begins at physical address 0x03000000
+and runs to 0x033fffff.
+On the RiscPC, EASI space runs from 0x08000000 to 0x0fffffff.
+The
+per-process data
+size
+for the current process
+is
+.Dv UPAGES
+long, and starts at VM_MAXUSER_ADDRESS.
