SubjectPATCH physical address typedef

Attached is a patch against 2.3.23 pre5 which adds 'kphysaddr_t' type.

The idea is to migrate code to using this type to store physical
addresses. This will help flag problematic iomap code via a warning --
since a lot of code uses char* instead of long to store physical
addresses. Also, IMHO it would be nice if the source code told us it
was storing a physical address, via the C type system. (same idea as
kdev_t, etc.)
