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.

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).

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.

oga was warned; it is a minimum requirement for inteldrm to be on.

any, or between netstart and local daemons if no fsck'ing. Also

Much more testing needed for this.

help worsen the interrupt race that dale is trying to fix. He'll get that
fixed, but for now, we can try to run macppc in the most reliable fashion.

this might need to be revisted later if its clear that there are machines
which only come up with a single state but more may appear after a PPC
change but for now we will just not initilize on systems with a single
state a boot. Solves a divide by zero panic when using the PDC diff on
broken hardware.

caused the PIC to not be initialized on resume, which caused much
badness - things attached to the ISA bus weren't getting any
interupts (for example, keyboards).
Also move around some of the lapic reinit code to handle some clock
initialization bits we weren't doing before.
Worked out by deraadt and myself.

These values were used to eventually pass ranges to uvm_pglistalloc(),
which has been fixed to correctly skip no-memory ranges a lot of time ago;
however mvme68k would still use the computed range and osiop would no
longer attach; this repairs it.

This is needed in the case where you need managed pages so you can
handle faulting and pmap_page_protect() on said pages when you manage
memory in such regions (i'm looking at you, graphics cards).
these pages are flagged PG_DEV, and shall never be on the freelists,
assert this. behaviour remains unchanged in the non-device case,
specifically for all archs currently in the tree we panic if called
after bootstrap.

in the IPI handler so that it works when it interrupts userspace,
waiting for the droppmap IPI to complete when destroying it, and
(most importantly) don't call pmap_tlb_droppmap() from cpu_exit().
Tested by myself and ckuethe, as our machines choked on the original.

still support all different methods of getting states without e.g.
(highest/lowest state), and on i386 use the tables. The only change
should be the deletion of the mV from the printf at boot.

IPIs are handled without blocking interrupts. This solves the random lockups
people have been seeing with apmd -C, thanks to marco@ for showing me how
to reliably recreate this hang, and claudio@ for telling me it was also
affecting his Athlon64 machine so I stopped chasing bugs in est.

immediately when biglock wasn't held. But there is nothing inherently
wrong with doing copyin/copyout faults without holding biglock, so
just remove the check because it prevent us from doing copyin in
syscall before we grab the biglock.

aperture, which will take your memory, bind it to agp, and return you the
aperture address. It's essentially the same as iommu on amd64 in the way it
works.
This will be used by the upcoming (works but is slow and will not be
enabled at first) drm memory management code for intel igp chipsets.
Right now the sync function for intagp is really slow (doing a wbinvd()
on every sync), this is in the process of getting fixed, but the size of
the diffs in my trees was getting silly.
