make kernels was originally documented (in commit r295099) as the same as make
universe -DJUST_BUILD_KERNELS. However, it used the UNIVERSE_TARGET=buildkernel
which is subtly different in that it also builds the toolchains and doesn't
build the LINT modules unless they happened to already exist in the tree. This
unbreaks POLA and just builds the kernels, including LINT, now rather than all
that other stuff as well. When the commit originally happened, the two just
differed by the LINT bug. r335711 introduced the universe dependency on the
toolchain that wasn't present before, which diverged the two further. This
restores the original intent of r295099.

And similar "unknown type name" errors for u_int, not recognizing bool as a type, etc.
This was caused by including <sys/param.h> too far down; move it up where it belongs.

Reported by: Jenkins via lwhsu
MFC with: r359438
KTLS uses the embedded header and trailer fields of unmapped
mbufs. This can lead to "silly" buffer lengths, where we have an
mbuf chain that will create a scatter/gather lists with a
regular pattern of 13 bytes followed by 16 bytes between each
adjacent TLS record.
For software ktls we typically wind up with a pattern where we
have several TLS records encrypted, and made ready at once. When
these records are made ready, we can coalesce these silly buffers
in sbready_compress by copying 13b TLS header of the next record
into the 16b TLS trailer of the current record. After doing so,
we now have a small 29 byte chunk between each TLS record.
This marginally increases PCIe bus efficiency. We've seen an
almost 1Gb/s increase in peak throughput on Broadwell based Xeons
running a 100% software TLS workload with Mellanox ConnectX-4
NICs.
Note that this change is ifdef'ed for KTLS, as KTLS is currently
the only user of the hdr/trailer feature of unmapped mbufs, and
peeking into them is expensive, since the ext_pgs struct lives in
separately allocated memory, and may be cold in cache.
This optimization is not applicable to HW ("NIC") TLS, as that
depends on having the entire TLS record described by a single
unmapped mbuf, so we cannot shift parts of the record between
mbufs for HW TLS.

pager needs to instantiate the buffer.

- Do not double-unbusy on error. Split unbusy for error case, which

In-tree gdb is essentially obsolete. We kept it for sparc64 (because
gdb in ports lacked sparc64 support) and as a fallback for crashinfo.
gdb was installed to /libexec on all archs other than sparc64, where the
WITHOUT_GDB_LIBEXEC option was default, with gdb installed to /usr/bin.
With sparc64's retirement WITH_GDB_LIBEXEC became the default for all
architectures, but it was still possible to set it off and install gdb
into /usr/bin.
As the next step in gdb's retirement, remove the option and install gdb
only into /libexec as the crashinfo fallback. We expect users to install
the gdb port or package for debugging. The in-tree gdb lacks support for
a number of supported architectures and does not support contemporary
DWARF debug info.
