2007-03-27	Clean up some return value handling now that we know that what's returned	Artur Grabowski
	is proper errnos. millert@ ok and some help
2007-03-26	Rip out the KERN_ error codes.	Artur Grabowski
	ok otto@
2007-03-25	Remove references to KERN_SUCCESS, okay miod@	Pedro Martelletto

2007-03-25	Remove the flags_lock simplelock from struct vm_map;	Thordur I. Bjornsson
	Cleanup the code accordingly. ok pedro@, art@
2007-03-25	remove KERN_SUCCESS and use 0 instead.	Artur Grabowski
	eyeballed by miod@ and pedro@
2007-02-25	Make integer wrap checks the same for mmap, munmap, msync, etc	Todd C. Miller
	by factoring most of the checks into a macro. OK otto@
2007-02-14	Consistently spell FALLTHROUGH to appease lint.	Jonathan Gray
	ok kettenis@ cloder@ tom@ henning@
2007-02-12	Let this compile with 'option DEBUG' again.	Tom Cosgrove
	ok dim@
2007-01-16	Implement multiple segment allocation for uvm_pglistalloc, which fixes	Dimitry Andric
	most agp_generic_bind_memory failures when memory is limited and very fragmented. In effect, this should fix a lot of X startup crashes after activities that exercise memory a lot (e.g. make builds, building big ports, etc). ok mickey, miod
2007-01-12	proper define for MAX_KMAPENT; miod@ ok	Michael Shalayeff

2007-01-12	Switch some lockmgr locks to rwlocks.	Artur Grabowski
	In this commit: - gdt lock on amd64 - sysctl lock - malloc sysctl lock - disk sysctl lock - swap syscall lock miod@, pedro@ ok (and "looks good" others@)
2006-11-29	We don't use mb_map anymore since a long time already. Remove it.	Miod Vallat

2006-11-29	Remove cpu_swapin() and cpu_swapout(), they are no longer necessary (except	Miod Vallat
	for cpu_swapin() on hppa* which is kept).
2006-11-29	Kernel stack can be swapped. This means that stuff that's on the stack	Miod Vallat
	should never be referenced outside the context of the process to which this stack belongs unless we do the PHOLD/PRELE dance. Loads of code doesn't follow the rules here. Instead of trying to track down all offenders and fix this hairy situation, it makes much more sense to not swap kernel stacks. From art@, tested by many some time ago.
2006-11-29	Add an alignment parameter to uvm_km_alloc1(), and change all callers to	Miod Vallat
	pass zero; this will be used shortly. From art@
2006-10-03	Introduce daddr64_t and use it for physical block numbers	Pedro Martelletto
	Okay weingart@, "I'm game with putting my name on it" dlg@
2006-07-31	fix uvmhist #2: args are always u_long so fix missing %d and %x and no %ll; ↵	Michael Shalayeff
	no change for normal code
2006-07-26	fix fmts for UVMHIST_LOG() entries making it more useful on 64bit archs; ↵	Michael Shalayeff
	miod@ ok
2006-07-13	Back out the anon change. Apparently it was tested by a few, but most of	Theo de Raadt
	us did not see it or get a chance to test it before it was commited. It broke cvs, in the ami driver, making it not succeed at seeing it's devices.
2006-06-29	fallout from previous: remmapping anonymous memory did not account dsize ↵	Michael Shalayeff
	proper; found by krause and mmap_fixed
2006-06-21	from netbsd: make anons dynamically allocated from pool.	Michael Shalayeff
	this results in lesse kva waste due to static preallocation of those for every phys page and also every swap page. tested by beck krw miod
2006-06-16	IS_VM_PHYSADDR is no longer used.	Miod Vallat

2006-06-10	Make uvn_sync_lock a rwlock, okay thib@ tedu@	Pedro Martelletto

2006-06-01	Make umv_pglistalloc() return EINVAL if it is asked for 0 bytes. This	Kenneth R Westerback
	will prevent panics in, e.g., bus_dmamem_alloc(). ok jason@ art@
2006-05-25	Enable optional specific handling of the u-area in pmap via PMAP_UAREA if	Miod Vallat
	defined; from NetBSD. Currently only used on xscale arm to use the mini data cache for u area mappings instead of the main data cache.
2006-05-16	tpyo	Michael Shalayeff

2006-05-07	remove drain hooks from pool.	Ted Unangst
	1. drain hooks and lists of allocators make the code complicated 2. the only hooks in the system are the mbuf reclaim routines 3. if reclaim is actually able to put a meaningful amount of memory back in the system, i think something else is dicked up. ie, if reclaiming your ip fragment buffers makes the difference thrashing swap and not, your system is in a load of trouble. 4. it's a scary amount of code running with very weird spl requirements and i'd say it's pretty much totally untested. raise your hand if your router is running at the edge of swap. 5. the reclaim stuff goes back to when mbufs lived in a tiny vm_map and you could run out of va. that's very unlikely (like impossible) now. ok/tested pedro krw sturm
2006-04-27	from PAE work:	Michael Shalayeff
	as paddr_t could be a long long (soon) always cast and print as llx.
2006-04-27	from PAE work:	Michael Shalayeff
	as freepages being vconverted back to byte address make sure to perform calculations in (upcoming) larger paddr_t to avoid losing higher bits in calculation.
2006-04-25	limit pool backend preallocation to 2048 pages max (which only affects >2g ↵	Michael Shalayeff
	physmem); miod@ toby@ ok
2006-04-06	Fix a process datasize leak with MAP_FIXED. When zapping old mappings	Kurt Miller
	call uvm_unmap_p instead of uvm_unmap so that it has the process information and can adjust vm_dused. okay pedro@ tedu@
2006-04-04	Revert r1.58, I was on drugs - the array we are locking is one byte per	Miod Vallat
	page, so the arithmetic was ok. Spotted by david@
2006-03-16	In sys_mincore(), pass a size in bytes, not pages, to uvm_vslock() and	Miod Vallat
	uvm_vsunlock(). ok mickey@
2006-03-06	deal w/ uvm_km_alloc() returning null; tedu@ ok	Michael Shalayeff

2006-03-06	do not panic unwiring unmapped memory (mmap3 regress); from netbsd; ↵	Michael Shalayeff
	kettenis@ tedu@ ok
2006-01-16	add another uvm histroy for physpage alloc/free and propagate a debugging ↵	Michael Shalayeff
	pgfree check into pglist; no functional change for normal kernels; make histories uncommon
2006-01-02	fix typo in comment	Tom Cosgrove
	ok deraadt@
2005-12-10	Don't check/free new_entry here, since it can't have been set. Spotted	Kenneth R Westerback
	by lint. "Probably a bogus cut'n paste." says moid. ok miod@ pedro@
2005-12-10	{en,re}trys -> {en,re}tries; eyeballed by jmc@	Miod Vallat

2005-11-29	apply patch from david hill for two netbsd prs:	Ted Unangst
	14060 skip MADV_SEQUENTIAL if refaulting 18037 missing pageactivate tested for some time by jolan krw
2005-11-25	do not use any casting in the atop/ptoa; tested on all archs by martin@ ↵	Michael Shalayeff
	miod@ mickey@
2005-11-19	Remove unnecessary lockmgr() archaism that was costing too much in terms	Pedro Martelletto
	of panics and bugfixes. Access curproc directly, do not expect a process pointer as an argument. Should fix many "process context required" bugs. Incentive and okay millert@, okay marc@. Various testing, thanks.
2005-11-15	Only two `h' in threshold.	Miod Vallat

2005-11-04	Add an extra flags argument to uvm_io(), to specify whether we want to fix	Miod Vallat
	the protection of the memory mapping we're doing I/O on, or if we want to leave them as they are. This should only be necessary for breakpoint insertion in code, so we'll only use it for ptrace requests. Initially from art@ after discussion with kettenis@ millert@ and I, tested by many.
2005-11-01	In uvm_swapout(), protect "p->p_swtime = 0;" with SCHED_LOCK() as is already	Aaron Campbell
	done in uvm_swapin(). Looks like this was a mistake made while editing. No response from art@. deraadt@, miod@, pedro@ ok
2005-10-27	Following a next pointer of an element deleted from a list is bad	Otto Moerbeek
	practise. Depending on the list implementation, this might or might not work; so make it use a safe idiom. ok pedro@ millert@ deraadt@
2005-10-23	typo	Pedro Martelletto

2005-10-06	typo	Brad Smith

2005-09-30	revert MAX_KMAPENT hack added just before 3.7 now that	Brad Smith
	a proper fix has been implemented in uvm_mapent_alloc(). ok pedro@
2005-09-30	Make ddb's 'show uvmexp' print information about kmapent, okay deraadt@	Pedro Martelletto
