Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out
...
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

switch all mpc6xx powerpc ports to NEWPMAP by default.
...
the old pmap is still available with the OLDPMAP option.

MAXSLP is defined to be a machine-independent scheduling parameter,
...
so move it into sys/param.h.

Per discussion w/ chuck and chuck, restructure the md page stuff
...
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
...
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

Now that we have direct-mapped pool pages, we can garbage-collect VM_MBUF_SIZE
...
and don't need to allocate mb_map.
