Before this change UNMAP completely blocked other I/Os while running.
Now it blocks only colliding ones, slowing down others only due to ZFS
locks collisions.

Improve cache control support, including DPO/FUA flags and the mode page.
At this moment it works only for files and ZVOLs in device mode since BIOs
have no respective respective cache control flags (DPO/FUA).
Make sure to not skip any argument when converting from deprecated
+POS1, -POS2 to -kPOS1,POS2, so that sort +0n gets translated to sort -k1,1n
as it is expected

- Fix XHCI driver for devices which have more than 15 physical root HUB
ports. The current bitmap array was too small to hold more than 16
bits and would at some point toggle the context size, which then would
trigger an enumeration fault and cause a fallback to the EHCI
companion controller, if any.
- Make sure we always set the maximum number of valid contexts.
- Set default cycle state in case of early interrupts.
- Add $netif_ipexpand_max to specify the upper limit for the number of
addresses generated by an address range specification. The default value
is 2048. This can be increased by setting $netif_ipexpand_max in rc.conf.

In kern_linkat() and kern_renameat(), do not call namei(9) while
holding a write reference on the filesystem. Try to get write
reference in unblocked way after all vnodes are resolved; if failed,
drop all locks and retry after waiting for suspension end.
- Use NULL instead of 0 for fpcurthread.
- Note the quirk with the interrupt enabled state of the dna handler.
- Use just panic() instead of printf() and panic(). Print tid instead
of pid, the fpu state is per-thread.
MFC r271924:
Update and clarify comments. Remove the useless counter for impossible, but
seen in wild situation (on buggy hypervisors).
When setting environment variables in the atrun script, use the
"export foo=bar" form instead of "foo=bar; export foo" since the
former allows the shell to catch variable names that are not valid
shell identifiers. This will cause /bin/sh to exit with an error
(which gets mailed to the at user) and it will not run the script.

Change the /var dataset in the default ZFS layout to have the
ZFS property canmount=off, making /var/db/pkg part of the / dataset, so
installed package files are consistent with the package database when
using ZFS boot environments (beadm).

Allow the PIC's IMR register to be read before ICW initialisation.
As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.
The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.
With this change, Linux kernels 3.15-rc2 and later won't hang
on boot when calibrating the local APIC.

rm -rf can fail sometimes with an error from fts_read. Make it
honor fflag to ignore fts_read errors, but stop deleting from
that directory because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple
rm -rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if
the directory is removed by another rm -rf. Since the intent of
the -f flag was to ignore errors, even if this was a bug in
fts_read, we should ignore the error like we've been instructed
to do.

many thanks for their continued support of FreeBSD.

Revert changes to shared code of the ixl and ixlv drivers to allow

Restrict the drivers to building on amd64 for now as it is

Just depend on PCI and neither INET nor INET6; also make sure we
can build individual drivers and they do not depend on each other
anymore.
