When called with an absolute pathname, periodic should attempt to execute
every script in that directory. If the directory does not exist, it should
print an error and exit 1. Due to a copy/paste mistake in r231568, it exits
0 in that case.

simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.
This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.

ZAC (Zoned-device ATA Command set) is the standard for addressing SMR
(shingled magnetic recording) devices over SATA. Drives indicate their
support for ZAC in their IDENTIFY block. Print whether and how a drive
supports ZAC in the output of "camcontrol identify".

Msdosfs allows setting READONLY by clearing the owner write bit of the file
mode. (While here, correct the misspelling of S_IWUSR as VWRITE. No
functional change.)
In msdosfs_getattr, intuitively reflect that READONLY attribute to userspace
in the file mode.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation.
Profiling via dtrace during a series of iperf tests I found 16111 / 30432
stack frames were located in mmu_booke_kextract(), so eliminating this
expensive call should improve performance slightly. XX_PhysToVirt() is not
as expensive, but redundant calls in this context is wasteful.
We currently support the a83t's r_intc in a somewhat hack-ish way; our .dts
describes it as nmi_intc, and uses a subset of the actual register space to
make it line up with a20/a31 nmi offsets.
This breaks with the recent 4.14 update describing r_intc using the full
register space, so update aw_nmi to use the correct register offsets with
the right compat data in a way that doesn't break our current dts with
nmi_intc or upstream with r_intc described.

According to the datasheet, TX_DESC_CTL is cleared when whole frame is transmitted or all
data in the current descriptor's buffer are transmitted.
When the mbuf and mapping are stored in the first segment and in a scenario where a tx
completion interrupt arrives for a frame and only the start of the next frame was transmitted,
at the time of interrupt processing the mbuf and mapping will be freed when processing the
first segment of the next frame but the other untrasmitted segments still need to use them.

In a multi segment frame, if the first tx descriptor is marked with TX_DESC_CTL
but not all tx descriptors for the other segments in the frame are set up,
the TX DMA may transmit an incomplete frame.
To prevent this, set TX_DESC_CTL for the first tx descriptor only when done
with all the other segments.
Also, don't bother cleaning transmitted tx descriptors since TX_DESC_CTL
is cleared for them by the hardware and they will be reprogrammed before
TX_DESC_CTL is reenabled for them.
