- Rework timeout handling, to make it more graceful for devices sharing
controller port (with PMP). Wait for other commands completion/timeout
before initiating recovery.
- Handle timeouts and fatal errors with port hard-reset. The rest of
recovery will be done by XPT on receiving async event. More gracefull
per-device soft-reset recovery can be implemented later.

- Add workaround for ATI SB600/SB700 PMP probe related bug, to speedup boot.
Most of the pieces came from Marius- correct settings for channels
and resource management. The one piece missing was that you cannot
for SBus cards replace 32 bit operations with A64 operations- not
supported.

reacquiring driver lock in Rx handler. re(4) drops a driver lock
before passing received frame to upper stack and reacquire the
lock. During the time window ioctl calls could be executed and if
the ioctl was interface down request, driver will stop the
controller and free allocated mbufs. After that when driver comes
back to Rx handler again it does not know what was happend so it
could access free mbufs which in turn cause panic.

do support 64bit addresses, the current SCRIPTS code supports only 32bit
addresses causing data corruption for buffer addresses >4GB. This problem
affects 64bit machines with more than 4GB RAM or amd64 with 4GB and
memory hole remapping.
Work-around this problem with a bus_dma tag that requests bounce-buffers
for addresses >4GB. This causes some overhead, but given the maximum SCSI
bus speed of 160MB/s compared, the effect should hardly be noticeable.
The problem was reported by Mike Watters (mike at mwatters net) who also
verified that this fix cures the problem.
Since this change is a NOOP on systems with less than 4GB RAM and fixes
data corruption (in RAM and on disk) on systems with more than 4GB, I hope
that this change is accepted for 8.0.

- Remove most of direct relations between ATA(4) peripherial and controller
levels. It makes logic more transparent and is a mandatory step to wrap
ATA(4) controller level into ATA-native CAM SIM.
- Tune AHCI and SATA2 SiI drivers memory allocation a bit to allow bigger
I/O transaction sizes without additional cost.
- Don't bother to assign vb until we know we have enough space
- Add variables for sx2, sy2, dx2, dy2 so that these aren't
calculated over and over, also reduce chance of errors.

obsoleted in 1996 by ATA-2, and crashes some modern hardware like some
revisions of the Serverworks K2 SATA controller. Even very ancient
hardware seems not to require it. In the unlikely event this causes
problems, the previous behavior can be re-enabled by defining
ATA_LEGACY_SUPPORT at the top of this file.

* iwnfw has now been split into individual modules so autoloading of
firmware module(s) does work again.
* Changes have been made to RUN -> AUTH transition, this should fix the
issue reported by Glen and others.
* Brandon reported issues in iwn_cmd() with large commands, those have
been fixed to.

Have the early USB takeover enabled for i386 and amd64
by default.
This also avoids a panic on PowerPC where the resource
isn't released properly and we find a busy resource
when the USB host controller wants to allocate it...
function may not work properly if we don't. Turn off hardware cursor as
vesa_set_mode() does.
- Add VBE 3.0 specific fields in VESA mode structure and pack it. Note
the padding is 190 bytes although VBE 3.0 says 189 bytes. It must be wrong
because the size of structure becomes 255 bytes and the specification says
it must be 256 bytes in total. In fact, an example code in the spec. does
it right, though. While we are at it, fix some i386-isms.
- Remove state buffer size limitation. It is no longer necessary since
sys/compat/x86bios/x86bios.c r198251.
- Move int 0x10 vector test into vesa_bios_post() as we always do it anyway.
