Linking the full version of clang 11 results in errors similar to:
lld: error: /usr/src/contrib/llvm-project/clang/lib/StaticAnalyzer/Frontend/AnalysisConsumer.cpp:736:(.text._ZN5clang4ento22CreateAnalysisConsumerERNS_16CompilerInstanceE+0xE0): relocation R_MIPS_CALL16 out of range: 48920 is not in [-32768, 32767]; references operator new(unsigned long)
Add -mxgot to the compilation flags for llvm libraries to work around
this error. This may be too big of a hammer, but it can always be
refined later.

Those messages were printed hundreds of times during boot, often multiple
times for each table. We already print information about the tables in

Currently, the output of `bectl list` doesn't align the 'Mountpoint' column
correctly when the 'mounted' property of a boot environment dataset is longer
than the default column width.
Set the 'Mountpoint' column width to the boot environment dataset with the
longest 'mounted' property or to the default width, whichever is greater.

This is a step towards facilitating jails with only Linux binaries.
Supporting emul_path adds path lookups which are completely spurious
if the binary at hand runs in a Linux-based root directory.

The checkpoints are another way of keeping the state of ZFS.
During the rewind, the pool has to be exported.
This makes checkpoints unusable when using ZFS as root.
Add the option to rewind the ZFS checkpoint at the boot time.
If checkpoint exists, a new option for rewinding a checkpoint will appear in
the bootloader menu.
We fully support boot environments.
If the rewind option is selected, the boot loader will show a list of
boot environments that existed before the checkpoint.

Since cubic calculates cwnd based on absolute
time, retaining RFC3465 (ABC) once-per-window updates
can lead to dramatic changes of cwnd in the convex
region. Updating cwnd for each incoming ack minimizes
this delta, preventing unintentional line-rate bursts.

of simply ignoring all control messages on such sockets, since we

Recent versions of UEFI have moved local APIC timer initialization into
the early SEC phase which runs out of ROM, prior to self-relocating
into RAM. This results in a hypervisor exit.
Currently bhyve prevents instruction emulation from segments that aren't
marked as "sysmem" aka guest RAM, with the vm_gpa_hold() routine failing.
However, there is no reason for this restriction: the hypervisor already
controls whether EPT mappings are marked as executable.
Fix by dropping the redundant check of sysmem.

This was discussed in arch@ a while ago. Most of the 16-bit drivers that it
relied on have been removed. There's only a few other drivers remaining that
support it, and those are very rare the days (even the once ubiquitious wi(1)
is now quite rare).
Indvidual drivers will be handled separately before pccard itself is removed.
Remove PC Card specific information. It's of little value these days and on
the way out after most of its drivers have been removed.
Use iwn instead of wi device.
