* Import M_CANFAIL support from NetBSD, removes a nasty panic during low-mem scenarios, instead generating an ENOMEM backfeed, ok tedu@, prodded by manyniklas2004-12-301-5/+6

* make check for too large allocations earlier, instead of fiddling with it.tedu2003-12-281-3/+3
| | | | | less error prone (no wraparound). no real functional change though. ok markus tdeval
* remove caddr_t casts. it's just silly to cast something when the functiontedu2003-07-211-4/+4

| | | | | | | | uses it as a hint for where to steal space from the parent map. We've been passing random stack garbage as that hint for ages. It's a wonder it didn't break things until we started working on Hammer. noone objected for at least a week.

* UBC was a disaster. It worked very good when it worked, but on someart2001-12-191-3/+3
| | | | | | | | | 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.
* If we assume (just pure speculation) that there will be a pmap sometime inart2001-12-051-3/+3
| | | | | | | the future that wants to allocate pv entries for every pmap_enter and wants to allocate those pv entries from kmem_map, it might be a good idea to init the kmem_map before initializing the kmemusage struct (because kmemusage allocates memory).
* make nkmempages dynamic based on memory. okay art@ from netbsd:provos2001-12-051-9/+72
| | | | | | | | | | | | | | date: 2000/02/11 19:22:52; author: thorpej; Add some very simple code to auto-size the kmem_map. We take the amount of physical memory, divide it by 4, and then allow machine dependent code to place upper and lower bounds on the size. Export the computed value to userspace via the new "vm.nkmempages" sysctl. NKMEMCLUSTERS is now deprecated and will generate an error if you attempt to use it. The new option, should you choose to use it, is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and NKMEMPAGES_MAX allow the user to configure the bounds in the kernel config file.
* Sync in more uvm from NetBSD. Mostly just cosmetic stuff.art2001-11-281-3/+3

* Bring in some new UVM code from NetBSD (not current).art2000-03-161-5/+5
| | | | | | | | | - 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.
