The hack-ish tricks to make the ANSI-style va_start macro work in

non-ANSI mode were not quite complete. This makes non-ANSI work.
Perhaps it would be better to eliminate this hack altogether...

thanks to john dyson for the first cut of this change.

fix a printf warning and add pmap_page_index declaration
1996-02-12 21:51:52 +00:00
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?

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.
