Commonly taskqueue_enqueue_timeout() is called from within the task
function itself without any checks for teardown. Then it can happen
the timer stays active after the return of taskqueue_drain_timeout(),
because the timeout and task is drained separately.
This patch factors out the teardown flag into the timeout task itself,
allowing existing code to stay as-is instead of applying a teardown
flag to each and every of the timeout task consumers.
Add assert to taskqueue_drain_timeout() which prevents parallel
execution on the same timeout task.
Update manual page documenting the return value of
taskqueue_enqueue_timeout().

AMD chipsets have proprietary mechanisms for dicovering resources.
Those resources are not discoverable via plug-and-play mechanisms
like PCI configuration registers or ACPI.
For this reason a chipset-specific knowledge of proprietary registers
is required.
At present there are two FreeBSD drivers that require the proprietary
resource discovery. One is amdsbwd which is a driver for the watchdog
timer in the AMD chipsets. The other is intpm SMBus driver when it
attaches to the newer AMD chipsets where the resources of the SMBus HBA
are not described in the regular PCI way.
In both cases the resources are discovered by accessing AMD PMIO space.
Thus, many definitions are shared between the two drivers.
This change puts those defintions into a common header file.
As an added benefit, intpm driver now supports newest FCHs built into
AMD processors of Family 15h, models 70h-7Fh and Family 16h, models
30h-3Fh.

The cxgbev/cxlv driver supports Virtual Function devices for Chelsio
T4 and T4 adapters. The VF devices share most of their code with the
existing PF4 driver (cxgbe/cxl) and as such the VF device driver
currently depends on the PF4 driver.
Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf
PCI device driver that attaches to the VF device. It then creates
child cxgbev/cxlv devices representing ports assigned to the VF.
By default, the PF driver assigns a single port to each VF.
t4vf_hw.c contains VF-specific routines from the shared code used to
fetch VF-specific parameters from the firmware.
t4_vf.c contains the VF-specific PCI device driver and includes its
own attach routine.
VF devices are required to use a different firmware request when
transmitting packets (which in turn requires a different CPL message
to encapsulate messages). This alternate firmware request does not
permit chaining multiple packets in a single message, so each packet
results in a firmware request. In addition, the different CPL message
requires more detailed information when enabling hardware checksums,
so parse_pkt() on VF devices must examine L2 and L3 headers for all
packets (not just TSO packets) for VF devices. Finally, L2 checksums
on non-UDP/non-TCP packets do not work reliably (the firmware trashes
the IPv4 fragment field), so IPv4 checksums for such packets are
calculated in software.
Most of the other changes in the non-VF-specific code are to expose
various variables and functions private to the PF driver so that they
can be used by the VF driver.
Note that a limited subset of cxgbetool functions are supported on VF
devices including register dumps, scheduler classes, and clearing of
statistics. In addition, TOE is not supported on VF devices, only for
the PF interfaces.

When the I/O MMU is active in bhyve, all PCI devices need valid entries

However, when new PCI devices were added at runtime either via SR-IOV or

Serbian locales have triple components to represent the 2 variations of the
locale: Latin and Cyrillic. Previously the tools generatic the locale were
appending both definitions instead of differentiating them.

Adopt the OpenBSD syntax for setting and filtering on VLAN PCP values. This
introduces two new keywords: 'set prio' to set the PCP value, and 'prio' to
filter on it.

installworld (although I am not sure why). I'll revisit this
change after I further understand the cause of the breakage.
Thanks to our secret canary (dhw) for the report.

the rest still to be investigated.

This is mostly fixing META_MODE with realinstall wanting a .meta
file when it does not need one. These targets really should
always run though since they have _SUBDIR on them.

- This was broken by r300350 and r300885.
- Add some comments around the external GCC logic since it is spread out
and in need of some cleanup.
- The problem was that X_COMPILER_TYPE is always defined from CC->XCC's
default, so if /usr/bin/cc is GCC (as it is on native powerpc64) then
X_COMPILER_TYPE was getting GCC and triggering the external logic in
Makefile.libcompat. It was intended to always provide -isystem with
GCC since --sysroot is used into the lib32 sysroot which won't modify
the header path without the -isystem. The use of the libc++/std=c++11
override was only intended to be used for external compilers though
(more accurately GCC 4.8+ but that's a separate assumption to
cleanup). Apply the same logic from Makefile.inc1 to Makefile.libcompat
to only add the libc++ override when needed for external compilers.

Due to META_MODE being passed into the environment it tends
to keep growing with the defaults.

This is a follow-up to r300343.
This is important for the OBJS_DEPEND_GUESS usage in
gnu/usr.bin/cc/cc_tools.
See comments for more details.

This is important to allow a Makefile to override OBJS_DEPEND_GUESS for
handling in META_MODE when its depend files are missing.

This will print a set of variables from make on error using
MAKE_PRINT_VAR_ON_ERROR. It is already enabled for the DIRDEPS_BUILD.
It may make sense to enable this in the non-meta mode as well once
people are more used to its more verbose error output.
This makes it much simpler to see which .meta file is used when a
command files so that it may be inspected for the build command.
