values in the global NFSv3 diskless structure as the mountroot
function is called during a serialized part of the boot, before
any other NFS client activity occurs.

doesn't. Most of the implementations have grown weeds for this so they
copy some fields from mnt_stat if the passed argument isn't that.
Fix this the cleaner way: Always call the implementation on mnt_stat
and copy that in toto to the VFS_STATFS argument if different.
commit. In the new world order, the transitive closure on the vector
operations is not precomputed. As such, it's unsafe to actually use
any of the function pointers in an indirect function call. They can
be null, and we need to use the default vector in that case.
This is mostly a quick fix for the four function pointers that are
ed explicitly. A more generic or scalable solution is likely to see
the light of day.

to implement the sanity check should have been changed when we converted
the implementation of vm_pindex_t from 32 to 64 bits. (Thus, RELENG_4 is
not affected.) The consequence of this error would be a legimate write to
an extremely large file being treated as an errant attempt to write meta-
data.

modifications to the inpcb IP options mbuf:
- Lock the inpcb before passing it into ip_pcbopts() in order to prevent
simulatenous reads and read-modify-writes that could result in races.
- Pass the inpcb reference into ip_pcbopts() instead of the option chain
pointer in the inpcb.
- Assert the inpcb lock in ip_pcbots.
- Convert one or two uses of a pointer as a boolean or an integer
comparison to a comparison with NULL for readability.
- Always check that index number passed from userland
is <= NG_NETFLOW_MAXIFACES. [1]
- Increase NG_NETFLOW_MAXIFACES up to 512. [2]

header. pf finds the first TCP/UDP/ICMP6 header to filter by traversing
the header chain. In the case where headers are skipped, the protocol
checksum verification used the wrong length (included the skipped headers),
leading to incorrectly mismatching checksums. Such IPv6 packets with
headers were silently dropped.

o Reject a GPT partition table if it's not preceeded by a PMBR.
There's no need to preserve the MBR partitioning anymore as GPT
is mature and with the first bullet extending the applicability
of GPT, it's better to be a bit more strict.
If we are resuming non-MPSAFE drivers, they need Giant held for them.
This may fix some obscure suspend/resume problems. It has fixed keyrate
setting problems that were triggered by cardbus (MPSAFE) changing the
ordering for syscons resume (non-MPSAFE). Also, add some asserts that
Giant is held in our suspend/resume and shutdown methods.
