* 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.

| | | | | | | | | - 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.
