62034405e6 allow kmem_malloc to return NULL if canwait is set and there's no map space 
left, rather than panic()ing.  This allows callers to set their own policy
for how to handle the shortage.  Add a few comments.

621153ce0e The unexpected remove of active kstack does happen on vax also, 
not only on pc532. I've verivied that this "fix" work.

37a292dea0 Make prototyping of most functions conditional on `PMAP_EXCLUDE_DECLS'. 
This allows MD pmap.h to implement access to those functions via pointers.

d0fd3d7e62 Don't declare pmap_page_index for now. It will break the arm port. 
This clearly needs to be fixed. I would like to declare it:

    __pure u_int     pmap_page_index __P((vm_offset_t));

but at least the arm port wants it signed [since it tests for -1 all over
the place]. Can we have this fixed please?

801712f01a Extend use of vm_object_prefer() to vm_allocate_with_pager(). 
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.

Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
