- thread_sleep_msg() -> uvm_sleep()
- initialize reference count lock in uvm_anon_{init,add}()
- 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.

- make sure that vsunlock doesn't unwire mlocked memory.
- fix locking in uvm_useracc.
- Return the error uvm_fault_wire in uvm_vslock (will be used soon).

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

on NetBSD's code, as well as some faked Posix RT extensions by me. This makes
at least simple linuxthreads tests work.

This is to match (make diffs smaller) the code in NetBSD.
new gcc inlines those functions, so this could also be a performance win.

- 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.

the access type that caused this mapping. This is to simplify pmaps
with mod/ref emulation (none for the moment) and in some cases speed
up pmap_is_{referenced,modified}.
At the same time, clean up some mappings that had too high protection.
XXX - the access type is incorrect in old vm, it's only used by uvm and MD code.
The actual use of this in pmap_enter implementations is not in this commit.

Mostly cleanups, but also a few improvements to pagedaemon for better
handling of low memory and/or low swap conditions.

to, at the bottom or the top, depending on your architecture's stack growth
direction. This is in preparation for Linux' clone(2) emulation.
port maintainers, please check that I did the work right.
