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
Software Developer's Manual Vol 3B_, June 2009. Almost all
of these counters relate to operations on the L2 cache.
Improve support for High-speed USB audio devices.
- fix issues regarding the mixer, where the interface number was not set in
time.
- fix wrong use of resolution parameter.

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
endpoint rather than per xfer and provide functions around get/free of resources.

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.

On Soft Reset, read device signature from FIS receive area, instead of
PxSIG register. It works better for NVidia chipsets. ahci(4) does the same.

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.

T3 firmware 7.8.0 for cxgb(4)
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.

Drop USB mass storage devices support from ata(4). It is out of the build as
long as I remember, and completely superseded by better maintained umass(4).
It's main idea was to optionally avoid CAM dependency for such devices, but
with move ATA to CAM, it is not actual any more.

- Extend XPT-SIM transfer settings control API. Now it allows to report to
SATA SIM number of tags supported by each device, implement ATA mode and
SATA revision negotiation for both SATA and PATA SIMs.
- Make ahci(4) and siis(4) to use submitted maximum tag number, when
scheduling requests. It allows to support NCQ on devices with lower tags
count then controller supports.
- Make PMP driver to report attached devices connection speeds.
- Implement ATA mode negotiation between user settings, device and
controller capabilities.
- Improve ATA mode/SATA revision control.
- fix a LOR between process lock and pmc thread mutex
- fix a system deadlock on process exit when the sample buffer
is full (pmclog_loop blocked in fo_write) and pmcstat exit.
It seems generation of link state change of e1000phy(4) is not
reliable on some Marvell PHYs. If msk(4) know it still does not
have established link check whether msk(4) missed the link state
change by looking into polled link state.
