This unbreaks m68k m88k sparc and perhaps others, which eventually froze
when hitting swap.
Tested by various people on various platforms.

machines or some configurations or in some phase of the moon (we actually
don't know when or why) files disappeared. Since we've not been able to
track down the problem in two weeks intense debugging and we need -current
to be stable, back out everything to a state it had before UBC.
We apologise for the inconvenience.

Contains also support for page coloring.

code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>.
Tested for the past few weeks by many developers, should be in a pretty stable
state, but will require optimizations and additional cleanups.

Including support for zeroing pages in the idle loop (not enabled yet).

into objects.
Gives the possibilty to mmap beyond the size of vaddr_t.

- Introduce a new type of map that are interrupt safe and never allow faults
in them. mb_map and kmem_map are made intrsafe.
- Add "access protection" to uvm_vslock (to be passed down to uvm_fault and
later to pmap_enter).
- madvise(2) now works.
- various cleanups.
|
|
Mostly cleanups, but also a few improvements to pagedaemon for better
handling of low memory and/or low swap conditions.
