2016-09-16	move the vm_page struct from being stored in RB macro trees to RBT functions	David Gwynne
	vm_page structs go into three trees, uvm_objtree, uvm_pmr_addr, and uvm_pmr_size. all these have been moved to RBT code. this should give us a decent chunk of code space back.
2015-08-21	Remove the unused loan_count field and the related uvm logic. Most of	Visa Hankala
	the page loaning code is already in the Attic. ok kettenis@, beck@
2014-12-17	remove lock.h from uvm_extern.h. another holdover from the simpletonlock	Ted Unangst
	era. fix uvm including c files to include lock.h or atomic.h as necessary. ok deraadt
2014-12-17	Prefer MADV_* over POSIX_MADV_* in kernel for consistency: the latter	Philip Guenther
	doesn't have all the values and therefore can't be used everywhere. ok deraadt@ kettenis@
2014-11-16	Replace a plethora of historical protection options with just	Theo de Raadt
	PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h. PROT_MASK is introduced as the one true way of extracting those bits. Remove UVM_ADV_* wrapper, using the standard names. ok doug guenther kettenis
2014-09-14	remove uneeded proc.h includes	Jonathan Gray
	ok mpi@ kspillner@
2014-05-08	Fix some potential integer overflows caused by converting a page number into	Mark Kettenis
	an offset/size/address by shifting by PAGE_SHIFT. Make uvm_objwrire/unwire use voff_t instead of off_t. The former is the right type here even if it is equivalent to the latter. Inspired by a somewhat similar changes in Bitrig. ok deraadt@, guenther@
2013-05-30	remove simple_locks from uvm code. ok beck deraadt	Ted Unangst

2010-05-01	Unbreak ramdisks.	Owain Ainsworth
	I forgot that uvm_object.c wasn't build if SMALL_KERNEL. Fix this by building the file unconditionally and only building the less used functions when SMALL_KERNEL is not defined. unbreaks ramdisk build. ok jsg@
2010-04-30	Right now, if anything internal changes with a uvm object, diverse	Owain Ainsworth
	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.
2010-04-21	the atomic primitives are still impossible to get at without using proc.h	Theo de Raadt
	(because it pulls in so much of the world) so include it for now, but mark it XXX ok tedu
2009-11-25	something hairy happened with cvs so this file didn't get added.	Owain Ainsworth
	re-add uvm_objwire and uvm_objunwire. "you may commit that" kettenis@ original diff oked by ariane@ and art@
2009-06-16	Backout all changes to uvm after pmemrange (which will be backed out	Owain Ainsworth
	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@.
2009-06-06	Add uvm_objwire() and uvm_objunwire(), I need this for some of my crazy	Owain Ainsworth
	shitz. Code mostly from netbsd with some tweaks from me. The loaning case is specifcically if 0ed out right now because we do not do loaning. ok ariane@, art@.
