NetBSD/sys/compat/sunos32/sunos32.h
dsl a065e51621 remove all the double (and triple) casts used to convert 32bit userspace
pointers to and from 64bit kernel pointers.  Instead use the defines
NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64)
to write a 32bit pointer throughout.
The 32bit pointer is now a struct to enforce the above.
amd64 (with linux emul) and sparc64 will both compile (when the arch stuff
goes in soon), and amd64 still runs some i386 binaries.
