1998-03-01Merge of MACHINE_NEW_CONTIG (aka MNN) code from Chuck Cranor,Niklas Hallqvist
<chuck@openbsd.org>. This code is as of yet disabled on all platforms, actually not yet supported on more than mvme68k, although other platforms are expected soon, as code is already available. This code makes handling of multiple physical memory regions consistent over all platforms, as well as keeping the performance of maintaining a single continuous memory chunk. It is also a requirement for the upcoming UVM replacement VM system. What I did in this merge: just declared the pmap_map function in a MD include file per port that needs it. It's not an exported pmap interface, says Chuck. It ended up in differnt include files on differnet ports, as I tried to follow the current policy on a per-arch basis.

<mycroft@netbsd.org> reorganization of the vm_collapse logic, although not used verbatim. We no longer collapse objects from the pagedaemon as that is not necessary anymore with the more aggressive collapses that gets done. This also increases performance of loaded systems. Much KNF too.

that case so that callers can deal with shortage rather than deadlocking.
