- Be prepared for dbuf to disappear in zfs_reclaim_complete() and check if
z_dbuf field is NULL - this might happen in case of rollback or forced
unmount between zfs_freebsd_reclaim() and zfs_reclaim_complete().
- On forced unmount wait for all znodes to be destroyed - destruction can be
done asynchronously via zfs_reclaim_complete().

* Don't try to use the source address, when its family is unspecified.
* If we get a join without a source, on an existing inclusive
mode group, this is an error, as it would change the filter mode.
Fix a problem with the handling of in_mfilter for new memberships:
* Do not rely on imf being NULL; it is explicitly initialized to a
non-NULL pointer when constructing a membership.
* Explicitly initialize *imf to EX mode when the source address
is unspecified.
This fixes a problem with in_mfilter slot recycling in the join path.

* Do not assume that the group lookup performed by imo_match_group()
is valid when ifp is NULL in this case.
* Instead, return EADDRNOTAVAIL if the ifp cannot be resolved for the
membership we are being asked to leave.
Caveat user:
* The way IPv4 multicast memberships are implemented in the inpcb layer
at the moment, has the side-effect that struct ip_moptions will
still hold the membership, under the old ifp, until ip_freemoptions()
is called for the parent inpcb.
* The underlying issue is: the inpcb layer does not get notification
of ifp being detached going away in a thread-safe manner.
This is non-trivial to fix.
But hey, at least the kernel should't panic when you unplug a card.

According to the specifications AMD/ATI SMBus controller is very
similar to SMBus controller found in PIIX4.
Some notable differences:
o different bit for enabling/signalling regular interrupt mode
o in practice seems to support only polling mode
Thus, intpm driver is modified to support polling-only mode
and to recognize SB700 PCI ID and differences.
Tested on: SB700 and PIIX4E platforms

X-Perhaps-ToDo: rename the driver to reflect its function
and supported hardware
- Make xterm/cons25 support runtime configurable. This allows me to
share libteken between syscons and my new vt driver.
- Add a fix to print blanks after printing a double width character to
prevent rendering artifacts.
- Add some more utility functions that I use in the vt driver.
- Improve newer AMD processor support (Family 0Fh Revision F and later).
- Adjust offset if DiodeOffet is set and valid. Note it is experimental
but it seems to give us more realistic temperatures. Newer Linux driver
blindly adds 21C for Family 0Fh desktop processors, however.
- Always populate dev.cpu and dev.amdtemp sysctl trees regardless of probe
order for consistency. Previously, dev.cpu.N.temperature was not populated
if amdtemp was loaded later than ACPI CPU driver and temperatures were not
accessible from dev.amdtemp.N.sensor0 tree for Family 10h/11h processors.
- Read the CPUID from PCI register instead of CPUID instruction to prevent
possible revision mismatches on multi-socket system.
- Change macros and variables to make them closer to AMD documents.
- Fix style(9) nits and improve comments.
Different sub-kinds of PCI buses may have different rules and
thus it is up for the bus backends to do proper input checks.
For example, PCIe allows configuration register numbers < 0x1000,
while for PCI proper the limit is 0x100.
And, in fact, the buses already do the checks.

X-ToDo: add check for negative value to bus backends
X-ToDo: use named constant for maximum PCIe register
API, keeping backward compatibility.
First consumer for this functionality is going to become forthcoming MPD-5.4,
supporting CoA and DR of RFC 3576: Dynamic Authorization Extensions to RADIUS.

"set vesa mode" and higher 16bits of the flag would be the desired mode.
One can now set, for instance, hint.sc.0.flags=0x01680180, which means
that the system should set VESA mode 0x168 upon boot.

FreeBSD 8, the compatibility shims should be built not just when FreeBSD 7
compatibility is requested, but also when compatibility with any older
FreeBSD version where that feature was present is requested.o
Without this patch, a kernel config that sets COMPAT_FREEBSD6 but not *7
would fail to build due to inconsistencies between the declaration of the
compatibility shims and their use in the SysV code.
There are similar errors in other *proto.h headers in the tree.

Rather than writing out a MID of '0', write a MID of 0x86 (aka
MID_I386) so that file gets it right.
This is a nop for boot2. It just checks the MAGIC part of the field,
ignoring the MID. boot2 is the only thing that loads this file, and
only on x86 so the MID_i386 is always the right value (the rest of the
code is already x86 specific).
