+.Sh NAME
+.Nm pmap_qenter ,
+.Nm pmap_qremove
+.Nd manage temporary kernel space mappings
+.Sh SYNOPSIS
+.In sys/param.h
+.In vm/vm.h
+.In vm/pmap.h
+.Ft void
+.Fn pmap_qenter "vm_offset_t sva" "vm_page_t *m" "int count"
+.Ft void
+.Fn pmap_qremove "vm_offset_t sva" "int count"
+.Sh DESCRIPTION
+The
+.Fn pmap_qenter
+function accepts a linear array of
+.Fa count
+pointers to wired pages
+.Fa *m ,
+and enters each of these pages into the kernel virtual address (KVA) space,
+beginning at the address
+.Fa sva .
+.Pp
+The
+.Fn pmap_qremove
+function tears out a mapping from the kernel virtual address space,
+beginning at
+.Fa sva
+and for
+.Fa count
+pages.
+.Sh IMPLEMENTATION NOTES
+The
+.Fn pmap_qenter
+function is intended for temporary mappings that do not require page
+modification or reference counting.
+Old mappings are simply overwritten.
+The pages
+.Em must
+be wired into physical memory.
+.Pp
+The corresponding
+.Fn pmap_qremove
+function is intended to remove such temporary mappings.
