Function pmap_map

freebsd/mips/mips/pmap.c:919–935

* Used to map a range of physical addresses into kernel * virtual address space. * * The value passed in '*virt' is a suggested virtual address for * the mapping. Architectures which can support a direct-mapped * physical to virtual region can return the appropriate address * within that region, leaving '*virt' unchanged. Other * architectures should map the pages starting at '*virt' and *

 *	Use XKPHYS for 64 bit, and KSEG0 where possible for 32 bit.
