legitimate for this to be set if vm_set_page_size() hasn't been called (it's
how the page size is communicated to vm_set_page_size()). Instead, test
for page_shift == 0; this is one of the values that vm_set_page_size()
initializes.
to vm_bootstrap_steal_memory(), since we may need to steal memory from
a direct-mapped segment at this early stage of the game (on e.g. MIPS
and Alpha).
This interface is activated by defining PMAP_STEAL_MEMORY in <machine/pmap.h>.
Otherwise, the pmap_virtual_space() prototype is in-scope for use by
vm_bootstrap_steal_memory().
results in reserved ephemeral ports starting at the top (as per
current practice), and shouldn't have a negative effect on normal
ephemeral ports...

called "MACHINE_NEW_NONCONGIG". this is required for UVM, the new VM
system (also written by chuck) that is coming soon. adds new functions:
vm_page_physload() -- tell the VM system about an area of memory.
vm_physseg_find() -- returns index in vm_physmem array that this
address is in.
and several new versions of old functions/macros defined in vm_page.h.
this is the sparc portion.

this is the MI portion. sparc, and then later i386 portions to come.
all other ports need to change to this ASAP! (alpha is already being
worked on)
one if the categories directories, will call "make readme" in
any subdirectories.
I thought that this was suggested by Chris Demetriou, but I can't find
any PR backing this up. So my apologies to the person who did suggest
this.
