- add uao_flush()
- replace boolean 'islocked' with 'lockflags'
- in uvm_fault() change FALSE to TRUE to in 'wide' fault handling
- get rid of uvm_km_get()
- various bug fixes

boolean_t pmap_extract(struct pmap *, vaddr_t, paddr_t *).
Matches NetBSD. Tested by various people on various platforms.

The highlight is some more advices to madvise(2).
o MADV_DONTNEED will deactive the pages in the given range giving a quicker
reuse.
o MADV_FREE will garbage-collect the pages and swap resources causing the
next fault to either page in new pages from backing store (mapped vnode)
or allocate new zero-fill pages (anonymous mapping).

From NetBSD.

We might want to use them on types that are bigger than vaddr_t.
Fix all callers that pass pointers without casts.

Implements mincore(2), mlockall(2) and munlockall(2). mlockall and munlockall
are disabled for the moment.
The rest is mostly cosmetic.

- 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.
