- 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.
- Use switch to assign color/format

- 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

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.
* DEAUTH is now handled correctly.

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.
splitting in bce(4) instead of (ab)using ZERO_COPY_SOCKETS that was not
propagated into if_bce.c anyway. It is disabled by default.

On error, freeze device queue, to allow periph driver to do proper recovery.
Freeze SIM queue only in some cases, when it is needed to protect SIM.
Implement better command timeout detection logic for non-queued commands.
This fixes false positives when command with short timeout waiting for the
long one. For example, when hald tastes CD during burning process.
Read and clear SERR register on interrupt.
instead of POSTREAD: the hardware do not touch this memory (CPU
updates it). It is already synchronized as PREWRITE after the
processing is done.
- Synchronize RX return ring memory in rx_eof. This is needed
as the deviced updates this memory when receives packets.
- Decouple the synchronization of BGE status block in the interrupt
service routine: perfrom PREREAD synchronization only all accesses
to this block are finished. This seems to be more natural.

has been yanked, this works around a cam recounting bug when
CAM_DEV_UNCONFIGURED is set late in the detach. In certain conditions the
reference to the XPT device would not be released which would cause the usb
explore thread to sleep forever on "simfree", preventing any new usb devices to
be found/ejected on the bus.
This is intended to be a quick workaround to the problem without touching CAM
so it can be merged to 8.0.
