b39701ef7e Stop using head(1) which is not available in installworld.
installworld should not be executing this anyhow but there is some
obscure case doing it still.  The head(1) binary is not part of
ITOOLS and there's no need to add it.

810fccd58a hwpmc: add summary command and further metadata extensions
metadata changes:
- log pmc sample rate with pmcallocate
- log proc flags with thread / process logging
  to identify user vs kernel threads

fixes:
- use log cpuid to translate event id to event name

Implement rudimentary summary command to track sample
counts by thread and process name within a pmc log.

d1ee857bcf Rework if_gif(4) to use new encap_lookup_t method to speedup lookup
of needed interface when many gif interfaces are present.

Remove rmlock from gif_softc, use epoch(9) and CK_LIST instead.
Move more AF-related code into AF-related locations.
Use hash table to speedup lookup of needed softc. Interfaces
with GIF_IGNORE_SOURCE flag are stored in plain CK_LIST.
Sysctl net.link.gif.parallel_tunnels is removed. The removal was planed
16 years ago, and actually it could work only for outbound direction.
Each protocol, that can be handled by if_gif(4) interface is registered
by separate encap handler, this helps avoid invoking the handler
for unrelated protocols (GRE, PIM, etc.).

This change allows dramatically improve performance when many gif(4)
interfaces are used.

107463a1fd Improve defaults for per-CPU kernel console colors, especially with 2
or 4 CPUs.  Add a compile-time option SC_KERNEL_CONS_ATTRS to control the
defaults.

Default to color numbers in reverse order to CPU numbers (instead of
in the same order with white first and wrapping to dark grey), so that
the brightest bright colors are used first.  Don't use dark grey at all;
replace it by dark green.

Syscons has too many compile-time options, but this one is needed in
in case the defaults give something like white on white, or the user
really hates this feature and can't wait to turn it off in rc.

c6a9955a40 Depart from normal man page proactice a little and provide guidance on
when to use assert, as well as providing a bad example of using
assert.  While not strictly necessary, experience has shown issues
with poor assert choice happen often enough that this departure seems
warranted. Also, tighten up the previous example (there's no need
to have extra paragraphs or gratuitously long lines).

39efbcff37 Enable lld as the system linker by default on amd64
The migration to LLVM's lld linker has been in progress for quite some
time - about three years ago I opened an upstream LLVM meta-bug to track
issues using lld as FreeBSD's linker, and about 1.5 years ago requested
the first exp-run with lld as the system linker.

As of r327783 we enabled LLD_BOOTSTRAP by default on amd64, using lld as
the linker to link the kernel and world, but GNU ld was still installed
as /usr/bin/ld.

The vast majority of issues observed when building ports with lld as the
system linker have now been solved, so set LLD_IS_LD by default on amd64
and install lld as /usr/bin/ld.  A small number of port failures remain
and these will be addressed in the near future.

Thanks to antoine@ for handling the exp-runs, krion@ for investigating
many port failures and adding LLD_UNSAFE or other fixes or workarounds,
and everyone who helped investigate, fix or tag ports.

a09337cf46 Add support for hardware rate limiting to mlx5en(4).
The hardware rate limiting feature is enabled by the RATELIMIT kernel
option. Please refer to ifconfig(8) and the txrtlmt option and the
SO_MAX_PACING_RATE set socket option for more information. This
feature is compatible with hardware transmit send offload, TSO.

A set of sysctl(8) knobs under dev.mce.<N>.rate_limit are provided to
setup the ratelimit table and also to fine tune various rate limit
related parameters.

7cecd58940 rescue: Restore 'make depend' call to fix WITH_META_MODE after r334008.
The rescue/crunchgen build avoids linking binaries for the objects it is
building by doing 'make foo.o bar.o' rather than 'make all'.  This breaks the
implicit 'beforebuild: depend' dependency which ensured that all source files
were generated and up-to-date before building the object files.  This
manifested as a WITH_META_MODE build problem for bin/sh in the rescue build
with syntax.{c,h} not properly being regenerated or recognized as changed in
the dependency graph.
