For some vague reason, it may be possible that scp->cursor_pos exceeds
scp->ysize * scp->xsize. This means that teken_set_cursor() may get
called with an invalid position. Just ignore the old cursor position in
this case.

1) A lock issue, if we ever had to try again
we would double lock the INP lock.
2) We were allowing (at wrap) associd 0... which really
we cannot allow since 0 normally means in most socket
API calls that we are wishing to effect something on
the INP not TCB.

by just returning EOPNOTSUPP. This will allow NFS server to fall back to
regular READDIR.
Note that converting inode number to snapshot's vnode is expensive operation.
Snapshots are stored in AVL tree, but based on their names, not inode numbers,
so to convert inode to snapshot vnode we have to interate over all snalshots.
This is not a problem in OpenSolaris, because in their READDIRPLUS
implementation they use VOP_LOOKUP() on d_name, instead of VFS_VGET() on
d_fileno as we do.

automatic link-local address configuration:
- Convert a sysctl net.inet6.ip6.accept_rtadv to one for the
default value of a per-IF flag ND6_IFF_ACCEPT_RTADV, not a
global knob. The default value of the sysctl is 0.
- Add a new per-IF flag ND6_IFF_AUTO_LINKLOCAL and convert a
sysctl net.inet6.ip6.auto_linklocal to one for its default
value. The default value of the sysctl is 1.
- Make ND6_IFF_IFDISABLED more robust. It can be used to disable
IPv6 functionality of an interface now.
- Receiving RA is allowed if ip6_forwarding==0 *and*
ND6_IFF_ACCEPT_RTADV is set on that interface. The former
condition will be revisited later to support a "host + router" box
like IPv6 CPE router. The current behavior is compatible with
the older releases of FreeBSD.
- The ifconfig(8) now supports these ND6 flags as well as "nud",
"prefer_source", and "disabled" in ndp(8). The ndp(8) now
supports "auto_linklocal".

The problem was introduced in SVN 180608/ rev 1.114 and affects
all users of callout_reset() (including select, usleep, setitimer).
A better fix probably involves replicating 'ticks' in the
struct callout_cpu; this commit is just a temporary thing so that
we can MFC it after a suitable test time and RE approval.

This is almost always pilot error.
We don't need to check for group filter UNDEFINED state at t1,
because we only ever allocate filters with their groups, so we
unconditionally reject such calls with EINVAL.
Trying to change the active filter mode w/o going through IP_MSFILTER
is also disallowed.
Deals with the case described in PR 137164 upfront, cumulative
with the fix in svn rev 197132 which only calls imo_match_source()
if the source address family was not unspecified.

- 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.

"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.
