The stage 2 arm64 page tables may need to start at a lower level. This
is because we may only be able to map a limited IPA range and trying
to use a full 4 levels will cause the CPU to fault in an unrecoverable
way.
To simplify the code we still allocate the full 4 levels, however level 0
will only ever be used to find the level 1 table used as the base. Handle
this by creating a dummy entry in the level 0 table to point to the level 1
table.

There are two ways to propagate the error in MMCCAM:
* Using cmd.error which is set by the peripheral driver;
* Using CCB status which is... also set by the driver.
The problem is that those two error conditions don't necessarily match.
This leads to the confusion when handling the MMC reply. So enforce the consistency
by panicking if request is marked as completed successfully but MMC-level error
is present (this hints to the programming error).

Since elftoolchain's cxxfilt is rather far behind on features, and we
ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
replacement.
It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.
Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.

Add some missing netlink_family definitions and produce vaguely
human-readable error messages for those definitions, like we used to do for
just ROUTE and KOBJECT_UEVENTS.
Additionally, if we know it's a netfilter socket but didn't find it in the
table, fall back to printing that instead of the generic handler ("socket
domain 16, ...").
No change to the emulator correctness, just mildly improved diagnostics for
gaps.
Alter shmget_allocate_segment and shmget_existing to take the values
they want from struct shmget_args rather than passing the struct
around. In general, uap structures should only be the interface to
sys_<foo> functions.
This makes on small functional change and records the allocated space
rather than the requested space. If this turns out to be a problem (e.g.
if software tries to find undersized segments by exact size rather than
using keys), we can correct that easily.

Stop advancing counter past the current iteration number at the start

The variable defaults to "/usr/local", unless sysctl returns some other
value for "user.localbase".
The value of user.localbase defaults to _PATH_LOCALBASE as defined in
paths.h and thus this commit has no immediate effect.
The purpose of this change is to make /etc/defaults/rc.conf automatically
use the value of _PATH_LOCALBASE when not set to the default value.

Calendar files that specify LANG=... to specify their character encoding did
also set the date format defined for that locale, resulting in output like:
Nov 4 Gabriel Faure dies from pneumonia in Paris, France, 1924
4 nov. N'oubliez pas les Charles !
After this commit the output is always printed in a consistent format
according to the user's current locale, e.g.:

I'll open a review asking for opinions whether this format change should

The problem is that Without walling /etc/rc.d/zfs on shutdown, resources
associated with ZFS mounts are not freed and the jails will remain in dying
state. In addition, the dataset is now in a dangling state, as the jail it
is attached to is dying.
A known workaround for jails was to add the following lines
to /etc/jail.conf, to make sure that "service zfs stop" is run
when the jail is stopped:
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.stop += "/usr/sbin/service zfs stop || /usr/bin/true";
While the workaround seems to be okay-ish for the jail situation, it is
still unclean. However, for physical hosts this may wreak havoc with the
pool if shared spares are used, as "zfs unshare" is never invoked on
shutdown.

Proxy the flag to the roughly analogous FreeBSD procctl 'TRACE'.
TRACE-disabled processes are not coredumped, and Linux !DUMPABLE processes

The main reason is that the project CI infrastructure is runned on Linux

Add a basic image specific for this case (called BASIC-CI for a lack of a
better name).
The image have no package pre-installed.
It only have a few modification to have dhcp client runned on the default

This adds a new target update-packages which will create the new packages
compared to the last run.
This is how to use it:
At this point we cut a release
$ make buildworld ...
$ make buildkernel
$ make packages
There is now a PKG_VERSION directory with latest link pointing to it
Distribute the packages to server
$ something something that update the source tree
$ make buildworld ...
$ make buildkernel
$ make update-packages
You know have a PKG_VERSION directory in the REPODIR and latest link pointing to it.
In PKG_VERSION dir only the packages which differs from the latest run are
named PKG_VERSION, otherwise the old packages are there.
The process is :
Build the new packages in the PKG_VERSION directory
Compare the internal data with the PKG_VERSION_FROM version. The comparison is done
by checking the internal hash of the packages.
By default PKG_VERSION_FROM is set to what the latest link points to.
If the old and new version matches, we rm the new package and cp the old one.

Use the native vnode lookup functions, instead of going via the LinuxKPI,

The vnode pointer is used as an identifier to identify XRCD handles which
are sharing resources.
This patch fixes the so-called XRCD support in ibcore for FreeBSD.
Refer to ibv_open_xrcd(3) for more information how the file descriptor

The multipage alignment requirements is incompatible with many aspects
of actual busdma code. Multi-page alignment requests are incompatible
with many aspects of current busdma code. Mainly with partially bounced
buffer segments and per-page loop in bus_dmamap_load_buffer(). Because
proper implementation would be a major restructuring of the code, add
the fix only for already known uses and do KASSERT for all other cases.
For this reason, bus_dmamap_load_buffer () should take the memory allocated
by bus_dmam_alloc () as one segment bypassing per page segmentation. We can
do this because it is guaranteed that the memory is physically continuous.
