Man page bits adapted from FreeBSD. OK miod@

Change to void function.
Also, no need to have global tty stats pointer, so just return it
from clalloc, as the caller frees it immediately anyway.

which is exactly what the macro does.
Macro's that are nothing more then:
#define FUNCTION(arg) function(arg)
are almost always pointless and should go away.
OK blambert@
Agreed by many.

where doing bremfree() befure calling buf_acquire().
This is causing us headache pinning down a bug that showed up
when deraadt@ too cvs to current, and will have to be done
anyway as a preperation for backouts.

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@.

is how sysctl finds them, so it can *never* be renumbered again, and must
stay

three
commits:
1) The sysctl allowing bufcachepercent to be changed at boot time.
2) The change moving the buffer cache hash chains to a red-black tree
3) The dynamic buffer cache (Which depended on the earlier too).
ok on the backout from marco and todd

indicates that writedisklabel is trying to find the location for writing
the label. If the lp is messed with, an invalid checksum is written.
done with miod and kettenis, lots of moaning and gnashing of teeth, etc

*and* PR_ZERO in flags, you will no longer zero our your nicely
constructed object.
Instead, now if you have a contructor set, and you set PR_ZERO, you will
panic (it's invalid due to how constructor work).
ok miod@ deraadt@ on earlier versions of the diff. ok tedu@ after he
pointed out a couple of places I messed up.
Problem initally noticed by ariane@ a while ago.

(just a noop since that doesn't matter in userland).
Pointed out by a couple of people, thanks.

and it is pretty critical so commiting it now. Any more fallout from
the code 'simplication'?

Just put it in the buf_acquire function.

This commit won't change the default behaviour of the system unless the
buffer cache size is increased with sysctl kern.bufcachepercent. By default
our buffer cache is 10% of memory, which with this commit is now treated
as a low water mark. If the buffer cache size is increased, the new size
is treated as a high water mark and the buffer cache is permitted to grow
to that percentage of memory.
If the page daemon is invoked, the page daemon will ask the buffer cache
to relenquish pages. if the buffer cache has more than the low water mark it
will relenquish pages allowing them to be consumed by uvm. after a short
period the buffer cache will attempt to re-grow back to the high water mark.
This permits the use of a large buffer cache without penalizing the available
memory for other purposes.
Above the low water mark the buffer cache remains entirely subservient to
the page daemon, so if uvm requires pages, the buffer cache will abandon
them.

alternate routing table and separate them from other interfaces in distinct
routing tables. The same network can now be used in any doamin at the same
time without causing conflicts.
This diff is mostly mechanical and adds the necessary rdomain checks accross
net and netinet. L2 and IPv4 are mostly covered still missing pf and IPv6.

ok krw@, miod@.
|

bounds information, ie. the zone of the disk that OpenBSD can use. Have each
pre-disklabel parser (MBR, DPME, or per-arch MD disklabel parsers) figure out
this area and pass it up to userland. Then, delete all the same disk parsing
code from disklabel(8) since the kernel passes it up. Lots and lots of - signs
in the disklabel(8) code.
Tested on as many platforms as possible, the fallout will be repaired as time
goes on. To test, use disklabel -d <drive> and validate that the bounds do not
overlap any boot blocks. This same information is used by disklabel -A...
OK for the concept from krw, miod, and drahn

over why the processes were being woken up at splvm after the page daemon
ran - and probably also had the page daemon running at splvm after the first
pass through the loop.

plain old disksort. we also keep the old method of queueing bufs
since some miods have crazy MD drivers that need some love.
