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

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.

was added in 2001. yes i got bitten by inet6 shit again.
in the ANEQ case, if af == AF_INET, (a)->addr32[0] != (b)->addr32[0]
is false when the adresses ARE equal. now it goes right in the
intended-for-v6 case and starts to compare the other addr32 fields -
in the v4 case I have garbage in them, so it reports all v4 as different
when they are in fact the same. fix by adding explicit af == INET6 test
before going on to compare the rest.
found the really hard way (many hours wasted, thought the bug was in my
new code) by me. ok sthen markus claudio

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.

no binary change and consistent with other usage of the macro.

system.
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.

Just put it in the buf_acquire function.

- change state properly in urtw_stop. disable interrupts, rx, and
tx. fixes scanning, ifconfig down, and some other issues
- fix rxgain; for ver. 2
- remove delays; that have been removed 8185 -> 8187

aperture, skip over dcache on i810 chipsets and stolen memory on later
chips.
I didn't notice this before because I mostly used this code with GEM
code, which doesn't use the stolen memory.

There are cases where the interface can be up but not running, for
instance if the driver's if_init routine fails halfway for whatever
reason (firmware file not found, hardware switch turned off etc...)
This is because in sys/net/if.c, the returned code of the driver
is ignored for SIOCSIFFLAGS and the IFF_UP flags is left set.
netintro(4) does not say anything about values returned by
SIOCSIFFLAGS, so I don't know whether it is the expected behavior
or not.
pointed out by halex@ and jacekm@ who noticed it was possible to
trigger a scan on wpi(4) even when the hardware switch was turned off.

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.
