driver when it hits a mbuf/iov buffer, it mallocs and copies the data
for processing.. This improves perf by ~8-10% on my machine...
I have thoughts of fixing AES-NI so that it can better handle segmented
buffers, which should help improve IPSEC performance, but that is for
the future...
PCI IDs into quirks, which mostly fit (though you'd get no argument
from me that AHCI_Q_SATA1_UNIT0 is oddly specific). Set these quirks
in the PCI attachment. Make some shared functions public so that PCI
and possibly other bus attachments can use them.
The split isn't perfect yet, but it is functional. The split will be
perfected as other bus attachments for AHCI are written.

imgp->interpreted to a bitmask instead of, functionally, a bool. Each
imgactivator now requires its own flag in interpreted to indicate whether
or not it has already examined argv[0].
Change imgp->interpreted to an unsigned char to add one extra bit for
future use.
With this change, one can execute a shell script from a 64bit host native
make and still get the binmisc image activator to fire for the script
interpreter. Prior to this, execution would fail.

tree support includes a device tree source compiler dtc(8) which
converts .dts files into .dtb files. /boot/loader will load dtb files
from this directory by default, allowing for fewer differences between
images for different SoCs. Compiled dts files will wind up here
eventually as an alternative to embedding them into the kernel.
Document this in hier(7), as well as add missing entries for
/boot/firmware and /boot/zfs, though the latter two should only be
considered place holders if someone wants to make them better.
previous seek location was 0. Without this, readdir() would see
dd_loc of zero and call getdirentries() which would start reading
entries at the current seek location of the directory ignoring the
first batch of entries. Also, rewinddir() should always seek so that
it reads the directory from the beginning to get updated entries.
