I held the mistaken belief this was completely unused. While the
driver is unused and likely not relevant for a long time,
sys/joystick.h lives on in maybe half a dozen ports, even though
hardware to use it hasn't been widely used in maybe 15 years.
Changelist:
- Move large parts of VALE code to a new file and header netmap_bdg.[ch].
This is useful to reuse the code within upcoming projects.
- Improvements and bug fixes to pipes and monitors.
- Introduce nm_os_onattach(), nm_os_onenter() and nm_os_onexit() to
handle differences between FreeBSD and Linux.
- Introduce some new helper functions to handle more host rings and fake
rings (netmap_all_rings(), netmap_real_rings(), ...)
- Added new sysctl to enable/disable hw checksum in emulated netmap mode.
- nm_inject: add support for NS_MOREFRAG

Finishes the conversion of the 40Gb Intel Ethernet drivers to iflib(9) for
FreeBSD 12.0, and fixes numerous bugs in both ixl(4) and iavf(4).
This commit also re-adds the VF driver to GENERIC since it now compiles and
functions.
The VF driver name was changed from ixlv(4) to iavf(4) because the VF driver is
now intended to be used with future products, not just with Fortville/Fort Park
VFs.
A man page update that documents these drivers is forthcoming in a separate
commit.

Both the in-kernel C variant and libc asm variant have very poor performance.
The former compiles to a single byte comparison loop, which breaks down even
for small sizes. The latter uses rep cmpsq/b which turn out to have very poor
throughput and are slower than a hand-coded 32-byte comparison loop.
Depending on size this is about 3-4 times faster than the current routines.

Building the kernel in Git repositories when git-svn is not available and
the "help.autocorrect" Git parameter is enabled results in Git trying to
replace the "svn" command (it does not know) with "serve". As a result the
output of the "git server" command is appended to the value of the
environmental variable VERINFO, which causes the auto generated vers.c
file to contain invalid C syntax (missing newline escapes):
#define "@(#)FreeBSD 12.0-ALPHA7 r000eversion 2
0015agent=git/2.19.0
000cls-refs
0012fetch=shallow
0012server-option

0000=5e2272613fa(splash-vt)\n"
Using `-c help.autocorrect=0` seems to be a good solution as it does not
modify user's environment. I am not sure, however, if we should use
programs (or Git commands), which we are not sure exist (we never check if
git-svn is available on the host), as there may be more unexpected
behaviors like this one.

The amd64 kernel started using ifunc for a variety of functions with
arch-specific implementations, and we would like to make use of the
same functionality on i386 and as much as possible avoid divergence
between i386 and amd64. In particular, future changes for security
improvements and mitigations may rely on ifunc support.

r338642 toggled the REPRODUCIBLE_BUILD knob but missed the
corresponding kern.opts.mk change.
We want to build the 12.0 release artifacts with reproducible builds
mode enabled. Switch it on in HEAD now to enable testing with upcoming
ALPHA builds. We can revisit the default setting for HEAD after the
branch is created.
This change eliminates the build metadata (user, hostname, timestamp,
etc.) from the kernel and loader. If the src tree is a git, svn or p4
checkout with changes then the metadata is retained.
The WITHOUT_REPRODUCIBLE_BUILD src.conf(5) knob can be used to revert
to the previous behaviour.

Both drivers use this interface so add a dependancy on it.
Since awg uses aw_sid for generating the MAC address, make it
depend on both aw_sid and nmvem so when only removing nvmem from
kernel config it will not include this driver.

newvers.sh supports two modes for reproducible builds:
-r Reproducible build. Do not embed directory names, user
names, time stamps or other dynamic information into
the output file. This is intended to allow two builds
done at different times and even by different people on
different hosts to produce identical output.
-R Reproducible build if the tree represents an unmodified
checkout from a version control system. Metadata is
included if the tree is modified.
Switch to the second mode when reproducible builds are enabled.
The value of a reproducible build is much less when building from an
uncontrolled, modified src tree, and -R likely provides the best
compromise in allowing the REPRODUCIBLE_BUILD knob to be enabled by
default for the release.

This was disabled recently due to lack of support in KDB disassembler
and DTrace FBT provider. Support for 'C'-extension to both of these was
added, so we can now enable 'C'-extension.
This reduces size of the kernel important for low-end embedded devices,
and saves cache footprint for high perfomance machines.

It's anticipated that after the freeze, this will be removed in
13-current (with the residual of the drm2 code copied to
sys/arm/dev/drm2 for the TEGRA port's use w/o the intel or
radeon drivers).
Due to the impending freeze, there was no formal core vote for
this. I've been talking to different core members all day, as well as
Matt Macey and Glen Barber. Nobody is completely happy, all are
grudgingly going along with this. Work is in progress to mitigate
