Similar to r300836, r301800, and r302550, cl and ct will always
be non-NULL as they're allocated using the mem_alloc routines,
which always use `malloc(..., M_WAITOK)`.

Deobfuscating the cleanup path fixes a leak where if cl was NULL and
cu was not, cu would not be free'd, and also removes a duplicate test for
cl not being NULL.

I don't know what errata is mentioned there, I was unable to find it, but
setting limit before the base simply does not work at all. According to
specification attempt to set limit out of the present window range resets
it to zero, effectively disabling it. And that is what I see in practice.
Fixing this properly disables access for remote side to our memory until
respective xlat is negotiated and set. As I see, Linux does the same.
At that point link is quite likely not established yet, so messing with
scratch registers is premature there. Original commit message mentioned
code diff reduction from Linux, but this line is not present in Linux now.
In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.

those system calls audit event identifiers AUE_READ and AUE_WRITE.
While auditing file-descriptor I/O is not required by the Common
Criteria, in practice this proves useful for both live and forensic
analysis.
NB: freebsd32 already assigns AUE_READ and AUE_WRITE to read(2) and
write(2).

about the desirability of auditing the number, as it was in fact in the
wrong place (in the common path for open(2) and openat(2), and only the
latter accepts a file-descriptor argument). Where other ABIs support
openat(2), it may be necessary to do additional argument auditing as it is
not performed in kern_openat(9).

Only first 256 wide chars are considered currently, all other are just
dropped from the range. Proper implementation require reverse tables
database lookup, since objects are really big as max UTF-8 (1114112
code points), so just the same scanning as it was for 256 chars will
slow things down.
POSIX does not require collation for [a-z] type ranges and does not
prohibit it for non-POSIX locales. POSIX require collation for ranges
only for POSIX (or C) locale which is equal to ASCII and binary for
other chars, so we already have it.
No other *BSD implements collation for [a-z] type ranges.
Restore ABI compatibility with unused now __collate_range_cmp() which
is visible from outside (will be removed later).
The bus_region_* APIs accept the number of data items to be read, while
the code was passing the total number of bytes, resulting in an overflow
of the SPROM parser's buffer.

LAPIC memory works only for 32-bit BARs, that are available only if split
BARs mode is enabled in BIOS. If it is not, complain loudly and fall back
to less efficient workaround.
Predicates are DIF objects whose return value is compared with zero to
determine whether the corresponding probe body is to be executed. The return
value itself is the contents of a 64-bit DIF register, but it was being
truncated to an int before the comparison. This meant that a predicate such
as /0x100000000/ would evaluate to false.

All armv6 processors are plenty fast enough for HZ=1000.
No changes are made for older arm systems, because some chips are a bit
wimpy for 1000 while others do fine, so it has to be set on a per-config
basis.
The code was successfully tested with FreeBSD, Linux, Solaris and Windows
guests. This interface is predictably slower (about 2x) then virtio-net,
but it is very helpful for guests not supporting virtio-net by default.
Thanks to Jeremiah Lott and Peter Grehan for doing original heavy lifting.
