This makes driver better track reported CAM_SEL_TIMEOUTs to properly
report device reappearance later. This fixes target 0 not reappearing
after initiator mode disabled and then reenabled.
It (mostly) allows to enable/disable initiator mode in run time.
Target mode control is blocked here to force coordination with CTL.
While there, add separate tunables/sysctls for virtual channels.
Previous implementation was too fragile to initiator parameters changes.
In case of port role change it could not survive different handle assigned
to the same initiator by firmware, even though initiator was logged out.
The new implementation should be more resillient to this kind of problems,
trying to work in any situation and only warn user about suspisious events.

MOVS instruction emulation.

don't support the PAT save/restore capability.
MFC r279540:
Fix warnings/errors when building vmm.ko with gcc.
Update vendor driver to 1.2.7. This update improves driver reliability and
adds support of 4Kn drives and report LUNs command.
Many thanks to HighPoint for providing this driver update.
This limit was in a previous version of the driver, but it is being re-
added to match the behavior of previous versions of 10. It prevents the
driver from using too many MSI-X vectors on systems with a large number of
logical CPU cores.
Thanks to <jwd@slowblink.com> for bringing up this issue.

Merge changes to libm from the past 9 months. This includes improvements
to the Bessel functions and adds the C99 function lgammal.
In case of target mode disable at least ISP2532 return invalid zero
ct_rxid value on CTIO completion. Try to workaround that using tag_id
from the CCB, pointed by still valid ct_syshandle.
I don't know whether this is valid fix or dirty hack, but considering that
alternative is indefinitely stuck command -- it worth trying.
- remove last remnants of never implemented multiple targets support;
- implement missing support for LUN mapping in this area.
Due to existing locking constraints LUN mapping code is practically
unlocked at this point. Hopefully it is not racy enough to live until
somebody get idea how to call sleeping fronend methods under lock also
taken by the same frontend in non-sleepable context. :(
At this point CTL has no known use case for device queue freezes.
Same time existing (considered to be broken) code was found to cause
modify-after-free issues.
The import of openssl to address the FreeBSD-SA-15:10.openssl security
advisory includes a change which rejects handshakes with DH parameters
below 768 bits. sendmail releases prior to 8.15.2 (not yet released),
defaulted to a 512 bit DH parameter setting for client connections.
The first fix committed last week changed the default to 1024 bits.
This commit fixes the case where the DHParameters option is set to a
file which doesn't exist, which is the case on newer versions of
FreeBSD which enable STARTTLS by default by auto-creating TLS
certificates.
Enable ttyu1, ttyu2, ttyu3 for arm installations.
This should make all consoles available, whether it
is VGA, HDMI, serial, or JTAG, but more importantly
enables all consoles when ttyu0 is not predictable.
For example, the Pandaboard ES apparently has three
consoles available, but the DB9/RS232 serial port is
ttyu2, so not available by default after the system
boots.
