further work on both older and newer chipsets.
Gleaned from the Linux tg3 driver. From Brad.

tidy up allocation of receive DMA maps. Previously the driver was
using DMA maps off the free list without fully allocating them, in
order to save two or three lines releasing them on error paths.
This was causing it to reuse a map already in use when under load.
From NetBSD.
Revert a workaround against a NULL pointer dereference on alpha
when invoking bus_dmaamp_sync.

backlight off.

While there switch some m_freem() to m_free() where only a single mbuf is
involved.

Alix boards suck a little bit less because it will be harder to live lock them

big uvm backout mess.

E.g. give up the MASTER status if there's a host with a lower
demote count, even if it has a higher advskew.
At the moment this shouldn't cause any change, but this is a
first step towards the removal of the
"bump the advskew to 240 in case of errors" hack,
without breaking backward compatibility.

this resolves the last of the pfsync traffic storm issues ive been able to
produce, and therefore makes it possible to do usable active-active
statuful firewalls with pf.
lots of testing locally on the production firewalls, also tested by sthen@

More backouts in line with previous ones, this appears to bring us back to a
stable condition.
A machine forced to 64mb of ram cycled 10GB through swap with this diff
and is still running as I type this. Other tests by ariane@ and thib@
also seem to show that it's alright.

We still have no idea why this stops the crashes. but it does.

This is for the same reason as the earlier backouts, to avoid the bug
either added or exposed sometime around c2k9. This *should* be the last
one.

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.

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).

since it was overlayed over a system that we warned would go "in to be
tested, but may be pulled out". oga, you just made me spend 20 minutes
of time I should not have had to spend doing this.

sync peers are able to get the states before the replies. previously there
was a race where the reply could hit a partner firewall before it had the
state for it, which caused the reply to get processed by the ruleset which
probably would drop it.
this behaviour is off by default because it does delay packets, which is
only wanted in active-active firewalls or when an upstream router is slow
to learn that you're moved the active member of the pfsync cluster. it also
uses memory keeping the packets in the kernel.
use "ifconfig pfsync0 defer" to enable it, "ifconfig pfsync0 -defer" to
disable.
tested by sthen@ who loves it. he's got manpage changes coming up for me.

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
