2002-10-29Since memory deallocation can't fail, remove the error return fromArtur Grabowski
uvm_unmap, uvm_deallocate and a few other functions. Simplifies some code and reduces diff to the UBC branch.
2002-02-28use red-black tree for lookup_entry. the red-black tree case forNiels Provos
map_findspace is still broken on alpha. this will make debugging easier. okay millert@
2002-02-25back out red-black tree. they are very fast but alpha UVM is broken andNiels Provos
the tree triggers the bug, PMAP_PREFER case was broken also.
2002-02-25use a red-black tree to find entries in the vm_map. augment the red-blackNiels Provos
tree to find free space between entries. speeds up memory allocation, etc...
2001-12-19UBC was a disaster. It worked very good when it worked, but on someArtur Grabowski
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.

2000-03-16Bring in some new UVM code from NetBSD (not current).Artur Grabowski
- 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.
