\fR
.SH "ARGUMENTS"
.TP
\fB\fIpdev\fB\fR
linux pci_dev representing the function
.TP
\fB\fIpaddr\fB\fR
host physical address to map
.TP
\fB\fIbyte_count\fB\fR
bytes to map
.SH "DESCRIPTION"
.PP
This is the main wrapper for mapping host physical pages to CA PCI space.
The mapping mode used is based on the devices dma_mask.  As a last resort
use the GART mapped mode.
