ws 2da166f660 Fix p_nice vs. NZERO code.
Change NZERO to 20 to always make p_nice positive.
On Christos' suggestion make p_nice explicitly u_char.

mrg 2fc2b98d83 make pageout sleep on vm_pages_needed rather than lbolt. this stops
pathological behaviour (freezes) when running short of free pages.  see
PR#2755 for a more detailed explanation (from jonathan).

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

cgd 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.

christos a818b81625 Added missing prototypes from <sys/cpu.h> 1996-04-23 12:25:23 +00:00
pk 37a292dea0 Make prototyping of most functions conditional on `PMAP_EXCLUDE_DECLS'.
This allows MD pmap.h to implement access to those functions via pointers.

christos c048d7ba68 fix a printf warning and add pmap_page_index declaration 1996-02-12 21:51:52 +00:00
christos 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?
1996-02-10 00:30:39 +00:00
christos b7b8db60ac change pmap_page_index to return __pure u_int, like in the majority of
the ports

pk 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.
