Peter Wemm 9154ee6aec Oops.. I nearly forgot the actual core of the length/rounding/etc fixes
that Bruce asked for.

These still are not quite perfect, and in particular, it can get
upset on extreme boundary cases (addr = 0xfff, len = 0xffffffff,
which would end up mapping a single page rather than failing), but
this is better code that I committed before.

(note, the VM system does not (apparently) support single mmap segment
sizes above 0x80000000 anyway)
