f8a6b48d66 Don't silently truncate the voff_t offset to vaddr_t when passing it to 
udv_attach. Pass the whole voff_t instead and do an explicite overflow
check before it is passed to the device's mmap handler (as "int", sadly).

9639d2bb98 modify udv_attach() and its caller (uvm_mmap()) so that it's passed the 
offset and size of the requested region to be mapped, so that the
udv_attach() can use the device d_mmap() entry to check mappability
of the requested region.

f2caacc717 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
