8 devmap_map \- device mapping create entry point
28 An opaque mapping handle that the system uses to describe the mapping currently
47 Flags indicating type of mapping. Possible values are:
74 User offset within the logical device memory at which the mapping begins.
92 A pointer to be filled in by device drivers with the driver private mapping
99 mapping setup time.  For example, in order for device drivers to support
100 context switching, the drivers allocate private mapping data and associate the
101 private data with the mapping parameters in the \fBdevmap_map()\fR entry point.
104 The system calls \fBdevmap_map()\fR after the user mapping to device physical
110 mapping in \fIpvtp\fR. The system expects the driver to allocate its private
