AR9285 and AR9287 parts are 100% untested.
only basic functionnalities are enabled for now.
committed over an AR9281.

that makes the PCIE device show up as a host bridge instead of a
PCI-PCI bridge. As a result any devices sitting behind it won't be
detected. Whack the device into PCI-PCI mode such that we can walk the
PCI bus hierarchy the normal way and detect all devices. Fixes PR 6215.

rather have the USB HCI emulate it during boot, while legacy mode is enabled.
This causes pckbd0 to attach as the console device, but is lost as soon as
the USB HCI driver attaches.
The disappearance of the emulated PS/2 controller can however be detected
in pckbc(4) - which is supposed to attach after [eou]hci(4), with the controller
refusing to ack commands and replying ``please resend'' instead.
In that case, the kernel will now no longer attach pckbd, and will perform a
new console input device selection, allowing the (real) usb keyboard to
become the console.
Thanks to krw@ for countless tests on legacy-free hardware; also tested on
more conventional hardware by naddy@ and I.
Only amd64 and i386 platforms are affected by this change.

errnos. Note that the error strings are being ignored, since we long ago
decided to not spam the console, and there is no other nice way to use the
errors (without changing the ioctls to pass it back)
The errno is now useful, since we can pass b_error from failing IO up, and
the drive can decide how to use that

right now, we do a pmap_kenter_pa(), we then get the pte (behind pmap's
back) and check for the cache inhibit bit (if needed). If it isn't what
we want (this is the normal case) then we change it ourselves, and do a
manual tlb shootdown (i386 was a bit more stupid about it than amd64,
too).
Instead, make it so that like on some other archs (sparc64 comes to
mind) you can pass in flags in the low bits of the physical address,
pmap then does everything correctly for you.
Discovered this when I had some code doing a lot of bus_space_maps(), it
was incredibly slow, and profilling was dominated by
pmap_tlb_shootwait();

No longer allocate a static amount of memory for messages in MD
boot path; message queues, message metadata, and message data now
all use dynamic memory, which means that runtime sysctls should now
be trivial to implement.
Since I'm going to be around all week to fix any breakage, this should
probably just go in now.

Now instead of the global object hashtable, we have a per object tree.
Testing shows no performance difference and a slight code shrink. OTOH when
locking is more fine grained this should be faster due to lock contention on
uvm.hashlock.
