Only four specific ATA PIO commands transfer several sectors per DRQ block
(interrupt). All other ATA PIO commands transfer one sector or 512 bytes
at one time. Hardcode these exceptions in mvs(4) with ATA_CAM option.
This fixes timeout of READ LOG EXT command used by `smartctl -x /dev/adaX`.
Also it fixes timeout of DOWNLOAD_MICROCODE on `camcontrol fwdownload`.
The reference HAL pushes a config group parameter to the driver layer
to inform it which particular chip behaviour to implement.
This particular value tags it as an AR9285.
The AR9485 chip and AR933x SoC both implement LNA diversity.
There are a few extra things that need to happen before this can be
flipped on for those chips (mostly to do with setting up the different
bias values and LNA1/LNA2 RSSI differences) but the first stage is
putting this code into the driver layer so it can be reused.
This has the added benefit of making it easier to expose configuration
options and diagnostic information via the ioctl API. That's not yet
being done but it sure would be nice to do so.
Tested:
* AR9285, with LNA diversity enabled
* AR9285, with LNA diversity disabled in EEPROM
SPC-4 specification states that serial number may be property of device,
but not a specific logical unit. People reported about FC storages using
serial number in that way, making it unusable for purposes of LUN multipath
detection. SPC-4 states that designators associated with logical unit from
the VPD page 83h "Device Identification" should be used for that purpose.
Report first of them in the new attribute in such preference order: NAA,
EUI-64, T10 and SCSI name string.
While there, make GEOM DISK properly report GEOM::ident in XML output also
using d_getattr() method, if available. This fixes serial numbers reporting
for SCSI disks in `geom disk list` output and confxml.

the release/generate-release.sh script by nwhitehorn.
This script can use optional configuration file to override defaults,
making running multiple serialzied builds with different specific
configurations or architecture-specific tunings quite easy.
Sample overrideable options are included in the release.conf.sample
file.

d_getattr(). Since these drivers use disk(9) KPI and not directly GEOM, use
of that function means KPI layering violation, causing extra g_io_deliver()
call for the request.
While GEOM in general has provider opened while sending BIO_GETATTR,
GEOM DISK does not really need to open disk to read medium-unrelated
attributes for own use.

This adds some new NetBSD releases and makes some simple formatting changes.
With this commit NetBSD and FreeBSD should have identical files.
DragonflyFBSD has the version immediately prior to this commit.
When committing to this file please try to coordinate with all three groups.

to 999.99% CPU. It still won't be aligned if you have a multithreaded
process using more than 1000% CPU (e.g. idle process on an idle 12-way
system), but 100% is a common case.

- When operating on a core file (-M) and -c is specified we don't clear
the message buffer of the running system.
- If we don't have permission to clear the buffer print the error message
only. That's what Linux does in this case, where this feature was ported
from, and it ensures that the error message doesn't get lost in the noise.

linux_file structure and use it instead of directly accessing td_fpop
when destroying the linux_file structure. The td_fpop pointer is not
valid when a cdevpriv destructor is run, and the type-specific close
method has already been called, so f_vnode may not be valid (and the
vnode might have been recycled without our own reference).

This is a workaround for WITH_LDNS_UTILS forcing BIND_UTILS off. It can
be reverted when we no longer have these conflicting options, or made more
general if we grow more cases like this.
