Put back in the simplification of the aiodone daemon. Previous "breakage" of the swap on arm64 has been found to be an issue on one machine the rockpro/arm64 related to a deadlock built into the sdmmc(4) stack interacting with swapping code both running under KERNEL_LOCK(). This issue is easily reproducible on -current and entering swap when building LLVM on a rockpro crashes the machine by memory corruption. Tested by mlarkin@ on octeon & i386, by myself on amd64 & arm64 and by sthen@ on i386 port bulk. ok beck@ some time ago. Previous commit message: Simplify the aiodone daemon which is only used for async writes. - Remove unused support for asynchronous read, including error conditions - Grab the proper lock for each page that has been written to swap. This allows to enable an assertion in uvm_page_unbusy(). - Move the uvm_anon_release() call outside of uvm_page_unbusy() and assert for the different anon cases. ok beck@, kettenis@

Use a per-UVM object lock to serialize the lower part of the fault handler. Like the per-amap lock the `vmobjlock' is principally used to serialized access to objects in the fault handler to allow faults occurring on different CPUs and different objects to be processed in parallel. The fault handler now acquires the `vmobjlock' of a given UVM object as soon as it finds one. For now a write-lock is always acquired even if some operations could use a read-lock. Every pager, corresponding to a different kind of UVM object, now expect the UVM object to be locked and some operations, like *_get() return it unlocked. This is enforced by assertions checking for rw_write_held(). The KERNEL_LOCK() is now pushed to the VFS boundary in the vnode pager. To ensure the correct amap or object lock is held when modifying a page many uvm_page* operations are now asserting for the "owner" lock. However, fields of the "struct vm_page" are still being protected by the global `pageqlock'. To prevent lock ordering issues with the new `vmobjlock' and to reduce differences with NetBSD this lock is now taken and released for each page instead of around the whole loop. This commit does not remove the KERNEL_LOCK/UNLOCK() dance. Unlocking will follow if there is no fallout. Ported from NetBSD, tested by many, thanks! ok kettenis@, kn@

Sprinkle uvm_obj_destroy() over UVM object recycling code. For now, only assert that the tree of pages is empty in uvm_obj_destroy(). This will soon be used to free the per-UVM object lock. While here call uvm_obj_init() when new vnodes are allocated instead of in uvn_attach(). Because vnodes and there associated UVM object are currently never freed, it isn't easy to know where/when to garbage collect the associated lock. So simply check that the reference of a given object is 0 when uvn_attach(). Tested by many as part of a bigger diff. ok kettenis@

R.I.P. UVM_WAIT(). Use tsleep_nsec(9) directly. UVM_WAIT() doesn't provide much of a useful abstraction. All callers tsleep forever and no callers set PCATCH, so only 2 of 4 parameters are actually used. Might as well just use tsleep_nsec(9) directly and make the uvm code a bit less specialized.

Don't leak swapslots when doing a uvm_km_pgremove and a page is in swap only. Before we were only calling uao_dropswap() if there was a page, maning that if the buffer was swapped out then we would leak the slot. Quite rare because only pipebuffers should swap from the kernel object, but i've seen panics that implied this had happened (alpha.p for example). ok thib@ after a lot of discussion and checking the semantics.

Right now, if anything internal changes with a uvm object, diverse places in the tree need to be touched to update the object initialisation with respect to that. So, make a function (uvm_initobj) that takes the refcount, object and pager ops and does this initialisation for us. This should save on maintainance in the future. looked good to fgs@. Tedu complained about the British spelling but OKed it anyway.

Prevent a possible case of lock recursion in swapoff. If when we have successfully swapped an aobj back in, then we release our reference count, and that reference is the last reference, we will free the the aobj and recursively lock the list lock. Fix this by keeping track of the last object we had a reference on, and releasing the refcount the next time we unlock the list lock.

Backout all changes to uvm after pmemrange (which will be backed out separately). a change at or just before the hackathon has either exposed or added a very very nasty memory corruption bug that is giving us hell right now. So in the interest of kernel stability these diffs are being backed out until such a time as that corruption bug has been found and squashed, then the ones that are proven good may slowly return. a quick hitlist of the main commits this backs out: mine: uvm_objwire the lock change in uvm_swap.c using trees for uvm objects instead of the hash removing the pgo_releasepg callback. art@'s: putting pmap_page_protect(VM_PROT_NONE) in uvm_pagedeactivate() since all callers called that just prior anyway. ok beck@, ariane@. prompted by deraadt@.

The first step in cleaning up the use of PG_RELEASED for uvm objects. Now, the PG_ RELEASED flag currently has two (maybe three) uses. The valid one is for use with async io where we want to free the page after we've paged it out. The other ones are "oh i'd like to free this, but someone else is playing with it". It's simpler to just sleep on the damned page instead and stop the fiddling. First step does uao's: in uao_detach, sleep on the object and free it when we're clean, instead of setting a flag so it's freed after. In uao_flush, do the same. Change the interation over the object in flush so that we don't have to add marker pages or other such voodoo to the list when we sleep (netbsd did that when they had a similar diff), just use the hash always. We can now change uao_releasepg() to just free the page, and not bother with the KILLME stuff. When the other objects are fixed this hook will vanish. Much discussion with art@ over the idea, and ariane@ over this specific diff. As mentioned, this one is based loosely on a similar idea in netbsd. Been in my tree for a while, survived many make builds, etc, and forcing paging using ariane's evil program. ok ariane@, beck@.

While splitting flags and pqflags might have been a good idea in theory to separate locking, on most modern machines this is not enough since operations on short types touch other short types that share the same word in memory. Merge pg_flags and pqflags again and now use atomic operations to change the flags. Also bump wire_count to an int and pg_version might go int as well, just for alignment. tested by many, many. ok miod@

Pool deals fairly well with physical memory shortage, but it doesn't deal well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.

Merge in -current from two days ago in the SMP branch. As usual with merges, they do not indicate progress, so do not hold your breath for working SMP, and do not mail me and ask about the state of it. It has not changed. There is work ongoing, but very, very slowly. The commit is done in parts as to not lock up the tree in too big chunks at a time.

Convert bzero to memset(X, 0..) and bcopy to memcpy. This is to match (make diffs smaller) the code in NetBSD. new gcc inlines those functions, so this could also be a performance win.
