b1f3262c73 Correctly initialise the TXQ link pointer to the last descriptor in
the last buffer in the list.

The current behaviour (due to me, so pointy hat is firmly on my head here)
was incorrect - it was setting the link pointer to the last descriptor
of the _first_ buffer in the TXQ.  Instead, it should have set it to the
last descriptor in the _last_ buffer in the TXQ.

This showed up as occasional TX stalls with frames in the TXQ but no
TX progress being made.  Further inspection showed the TXQ looked like
it contained multiple "lists" of frames - there'd be a list of correct
frames, then a NULL link pointer, but there'd be a next buffer in the
list.

Since this code is only called upon an interface reset, it's likely
this only began showing up when I started doing stress testing
in environments which annoy the radios enough to cause lockups.

I've not yet any TX stalls with this patch applied.

6e9dcee4ca Save more of config space for PCI Express and PCI-X devices.
Expand pci_save_state and pci_restore_state to save more of
the config state for PCI Express and PCI-X devices. Various
writable control registers are present in PCI Express that
can potentially be lost over suspend/resume cycle.

This change is modeled after similar functionality in Linux.

035e4e0494 Add support for ns timestamps and birthtime to the ext2/3 driver.
When using big inodes there is sufficient space in ext3 to
keep extra resolution and birthtime (creation) timestamps.
The appropriate fields in the on-disk inode have been approved
for a long time but support for this in ext3 has not been
widely  distributed.

In preparation for ext4 most linux distributions have enabled
by default such bigger inodes and some people use nanosecond
timestamps in ext3. We now support those when the inode is big
enough and while we do recognize the EXT4F_ROCOMPAT_EXTRA_ISIZE,
we maintain the extra timestamps even when they are not used.

An additional note by Bruce Evans:
We blindly accept unrepresentable tv_nsec in VOP_SETATTR(), but
all file  systems have always done that.  When POSIX gets around
to  specifying the behaviour, it will probably require certain
rounding to the fs's resolution and not rejecting the request.
This unfortunately means that syscalls that set times can't
really tell if they succeeded without reading back the times
using stat() or similar and checking that they were set close
enough.

  bzero() the full compressed update struct before setting the values.
  This is needed because pf_state_peer_hton() skips some fields in certain
  situations which could result in garbage beeing sent to the other peer.
  This seems to fix the pfsync storms seen by stephan@ and so dlg owes me
  a whiskey.

I didn't see any storms, but this definitely fixes a useless memory
allocation on the receiving side, due to non zero scrub_flags field
in a pfsync_state_peer structure.

723616952d At the risk of reducing source compatibility with old NetBSD and Sprite:
o) Get rid of some unused macros related to features we don't intend to
   provide.
o) Get rid of macro definitions for MIPS-I CPUs.  We are not likely to
   support anything that predartes MIPS-III.
o) Respell MIPS3_* macros as MIPS_*, which is how most of them were being
   used already.
o) Eliminate a duplicate and mostly-unused set of exception vector macros.

There's still considerable duplication and lots more obsolete in our headers,
but this reduces one of the larger files to a size where one could reckon
about the correctness of its contents with a mere few hours of contemplation.

There is, of course, a question of whether we need definitions for fields,
registers and configurations that we are unlikely to ever use or implement,
even if they're not obsolete since 1991.  FreeBSD is not a processor
reference manual, and things that aren't used may be wrong, or may be
duplicated because nobody could possibly actually know whether they're
already defined.
