Note that r200091 completely overrides r200053 and the merge of the
former is recorded for bookkeeping only.
r200091 won't be merged to 'more stable' branche(s) because of the POLA.
ndis_scan_results() can sleep if the scan results are not ready when
ndis_scan() is called. However, ndis_scan() is invoked from softclock()
and cannot sleep. Move ndis_scan_results() to the ndis driver's scan_end
hook instead.
Unbreak the ata_atapi() usage. Since r200171 (MFC'ed in r200432) the
mode setting functions get a ata_device type device passed instead of
a ata_channel one, thus ata_atapi() has to be adjusted accordingly.

Large I/Os on Promise controllers reported to cause UDMA ICRC errors and
subsequent timeouts. Restore previous limit for now, at least until
I will have hardware to experiment.

- On entrance to the rx_eof sync RX rings maps with POSTWRITE flag
instead of POSTREAD: the hardware do not touch this memory (CPU
updates it). It is already synchronized as PREWRITE after the
processing is done.
- Add support for new BGE chips (5761, 5784 and 57780). These chips uses new
BGE_PCI_PRODID_ASICREV register to store the chip identifier and its revision.
- Add new grouping macro for 7575+ chips (BGE_IS_5755_PLUS).
- Add IDs for Fujitsu-branded Broadcom adapters.
Some general cleanup of scatter/gather memory allocation
- We don't need to check malloc return values with M_WAITOK
- remove variables that we don't really need
- cleanup the error paths by just calling drm_sg_cleanup()
- fix drm_sg_cleanup() to be safe to call at any time
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this option deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.
As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.(ata|atapi)_dma tunable work again.
Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

Limit maximum I/O size, depending on command set supported by device.
It is required to suppot non-LBA48 devices with MAXPHYS above 128K.
Same is done in ada(4).
Add counters for the i7 architecture which were accidentally left
out of the original commit of i7 support. These are all the counters
on pages A-32 and A-33 of the _Intel(R) 64 and IA32 Architectures

of these counters relate to operations on the L2 cache.

Remove overuse of exclamation marks in kernel printfs, there mere fact a
message has been printed is enough to get someones attention. Also remove the
line number for DPRINTF/DPRINTFN, it already prints the funtion name and a
unique message.
Disable interrupts after doing early takeover of the usb controller in case usb
isnt actually compiled in (or kldloaded) as the controller could cause spurious
interrupts.
Improve High Speed slot allocation mechanism by moving the computation to the

updates device entries supported with the product name not magic numbers
and sorts entries. WUSB54GCV2 is added.
overhauls urtw(4) for supporting RTL8187B devices properly that there
was major changes to initialize RF chipset and set H/W registers and
removed a lot of magic numbers on code.
Reduce probe priority of USB input devices to BUS_PROBE_GENERIC from
BUS_PROBE_SPECIFIC. This allows device-specific drivers like atp to
attach reliably.
Do not ignore device interrupt if bus mastering is still active. It is
normal in case of media read error and some ATAPI cases, when transfer size
is unknown beforehand. PCI ATA BM specification tells that in case of such
underrun driver should just manually stop DMA engine. DMA engine should
same time guarantie that all bus mastering transfers completed at the moment
of driver reads interrupt flag asserted.
This change fixes interrupt storms and command timeouts in many cases.

Explicitly acknowledge MSI completion, as required by SiI3124 datasheet.
It makes MSI working there. Later (and cheaper) PCIe chips (3132/3531)
still randomly crashing system in few seconds of high MSI rates, generating
something inaporopriate, like NMI or "Fatal trap 30".
Add Asynchronous Notification support for controllers without SNTF
capability by snooping SDB FIS receive area. It should be even faster
then regular way, but less reliable.

lindev(4) [1] is supposed to be a collection of linux-specific pseudo
devices that we also support, just not by default (thus only LINT or
module builds by default).
While currently there is only "/dev/full" [2], we are planning to see more
in the future. We may decide to change the module/dependency logic in the
future should the list grow too long.
This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.
