o Only set 4-bit caps on those boards that have 4-bit caps (this means that
because we don't set wire4 yet, this forces us to always use 1-bit bus).
o Don't test wire4 when setting up the bus width, since bad things will
happen if we do.

VOP_MARKATIME() since unlike the rest of VOP_SETATTR(), VA_MARKATIME
can be performed while holding a shared vnode lock (the same functionality
is done internally by VOP_READ which can run with a shared vnode lock).
Add missing locking of the vnode interlock to the ufs implementation and
remove a special note and test from the NFS client about not supporting the
feature.

In archive_write_disk: If archive_write_header() fails to create
the file, that's a failure and should return ARCHIVE_FAILED.
Metadata restore failures still return ARCHIVE_WARN, because
that's non-critical. Fix test_write_disk_secure test to
verify the correct return code in one case; add test_write_disk_failures
to do another very simple test of restore failure.
This should fix cpio coredumping when it tries to restore to
a write-protected directory.

section of code, this uses WITNESS_NORELEASE() and WITNESS_RELEASEOK() to mark
the boundaries. Both functions require the lock to be held when calling.
This is intended for scenarios like a bus asserting that the bus lock is not
dropped during a driver call. There doesn't appear to be a man page to
document this in.

- Always program RX configuration register from scratch instead of
doing read/modify/write.
- Rename re_setmulti() to re_set_rxmode() to be reflect reality.
- Simplify hash filter logic a little while I am here.

There are still several signed/unsigned warnings left, which
require a bit more study for a proper fix.
This file has grown beyond reasonable limits.
We really need to split it into separate components (ipv4, ipv6,
dummynet, nat, table, userland-kernel communication ...) so we can
make mainteinance easier.

about invalid timestamps. Nehalem CPUs seem to be synchronized but only
within a fraction of a microsecond.
- Make the Counter code more flexible to poor timestamps. In general we
now complain a lot but render as much as we can.
- Change the scaler behavior so it works better with very long and very
short traces. We now set the maximum scale such that it properly
displays the entire file by default and doesn't permit zooming out
beyond the file. This improves other awkward navigation behavior.
The interval is now set very small which can't be achieved by simply
dragging the mouse. Clicking to the left of or right of the scaler bar
will produce increments of a single, very small, interval now.

invalidates the value in fsbase msr, thus value in %r9 can not be
considered the current value for fsbase anymore.

Even though VT100-like devices can display non-ASCII characters, they do
not use an 8-bit character set. Special escape sequences allow the VT100
to switch character maps. The special graphics character set stores the
box drawing characters, starting at 0x60, ending at 0x7e. This means
we now pass the character map tests in vttest, even the save/restore
cursor test, combined with character maps. dialog(1) also works a lot
better now.
This commit also includes some other minor fixes:
- Default to 24 lines in teken_demo when using xterm emulation.
- Make white foreground and background work in teken_demo.
address space where to put vnode pages, and then call UFS_BALLOC(),
to actually allocate new block and map it. When UFS_BALLOC() returns
error, sometimes we forget to revert the vm object size increase,
allowing for the pages that are not backed by the logical disk blocks.
Revert vnode_pager_setsize() back when UFS_BALLOC() failed, for
ffs_truncate() and ffs_write().

vnode, from -1 down. When vinvalbuf(vp, V_ALT) is done for the vnode, it
incorrectly does vm_object_page_remove(0, 0), removing all pages from
the underlying vm object, not only the pages that back the extended
attributes data.
Change vinvalbuf() to not remove any pages from the object when
V_NORMAL or V_ALT are specified. Instead, the only in-tree caller
in ffs_inode.c:ffs_truncate() that specifies V_ALT explicitely
removes the corresponding page range. The V_NORMAL caller
does vnode_pager_setsize(vp, 0) immediately after the call to
vinvalbuf(V_NORMAL) already.

In normal operation, the number of cache entries is roughly equal to the
number of active vnodes. However, when most of the recently accessed
vnodes have many hard links, the number of cache entries can be 32000
times as large, exhausting kernel memory and provoking a panic in
kmem_malloc().
