explicit access control checks to delete and list extended attributes
on a vnode, rather than implicitly combining with the setextattr and
getextattr checks. This reflects EA API changes in the kernel made
recently, including the move to explicit VOP's for both of these
operations.

UMA_ZFLAG_INTERNAL zones at all. Apparently, Wilko's alpha
was crashing while entering multi-user because, I think, we
were calculating the garbage cachefree for pcpu caches that
essentially don't exist for at least the 'zones' zone and it so
happened that we were reading from an unmapped location.

Improve vertical compactness by using a IGMP_PRINTF() macro rather
than #ifdefing IGMP_DEBUG a large number of debugging printfs.

are all bogus, and the cards that don't decode things quite right
often have hundreds of them. This will fix starvation of small dmesg
buffers and allow better debugging to happen. I thought about adding
an override, but there is such a thing as too many knobs. :-)
ntp_update_second twice when we have a large step in case that step
goes across a scheduled leap second. The only way this could happen
would be if we didn't call tc_windup over the end of day on the day of
a leap second, which would only happen if timeouts were delayed for
seconds. While it is an edge case, it is an important one to get
right for my employer.

ultimate trigger for the follow-up fixes in revisions 1.78, 1.80,
1.81 and 1.82 of trap.c. I was simply too pre-occupied with the
gateway page and how it blurs kernel space with user space and
vice versa that I couldn't see that it was all a load of bollocks.
It's not the IP address that matters, it's the privilege level that
counts. We never run in user space with lifted permissions and we
sure can not run in kernel space without it. Sure, the gateway page
is the exception, but not if you look at the privilege level. It's
user space if you run with user permissions and kernel space otherwise.
So, we're back to looking at the privilege level like it should be.
There's no other way.

- Fix up TX speed changes.
- Make mpi-350 cards sort-of work with new firmware. It RXs okay but TXs
only work for about 14 packets then fails to get an interrupt. The
TX watchdog fires. It has been reported that my hack for now doesn't
break cards with the older firmware. It appears my card has lost
the ability to RX or TX at all but other peoples cards work. I assume
it got damaged in tansport.

count handling of station entries in hostap mode:
Input path:
o driver is now expected to find the node associated with the
sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
use within the wlan module and is responsible for cleaning up
on return
o the antenna state is no longer passed up with each frame; this
is now considered driver-private state and drivers are responsible
for keeping it in the driver-private part of a node
Output path:
Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode). On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver. This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node. This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock. As a byproduct we also reduce the overhead
for sending management frames (minimal). Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame. Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler). This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.
Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
pointers may never be null)
that caused a 3-4 times slow down in performance.
(the primary Sparc64 developers are all using OFW_NEWPCI already, so it is
the best code path for users)
quietly discard them; this just permits them to be collected with bpf)
o add a counter for the number of rate control frames discarded when not in
monitor mode
o move the rx "too short" statistic in the stat structure so non-error rx stats
are together (NB: ABI change to apps that collect stats via driver ioctl)
mistakes (this mistake was not an issue because the length is only used to
decide whether or not to allocate a cluster)
o while here, move a beacon length comment to the "right place"
_pmap_allocpte(): Guarantee that the page table page is zero filled before
adding it to the directory. Otherwise, a 2nd, 3rd, etc. thread could

* pim_register_prepare() uses the appropriate sw_csum flag to
call ip_fragment() so the IP checksum is computed properly.
* Modify pim_register_prepare() to take care of IP packets that

* Add-back in_delayed_cksum() to encap_send(), because it seems it
should be there.

present, and non-zero when it is (or may be) absent. The test
cbb_child_present was backwards. However, typical usage in the tree
would cause it to do the right thing because the card really wasn't
there the OK flag would be turned on.
Also, assume that if any of these bits are turned on we don't have a
card, rather than requiring both of them in the suspend/resume
routines.

directories. Previously, pfs_iterate() would return -1 when it
reached the end of the process list while processing a process
directory node, even if the parent directory contained further nodes
(which is the case for the linprocfs root directory, where the process
directory node is actually first in the list). With this patch,
pfs_iterate() will continue to traverse the parent directory's node
list after exhausting the process list (as was the intention all
along). The code should hopefully be easier to read as well.
While I'm here, have pfs_iterate() assert that the allproc lock is
held.
to what is in NetBSD. I have a few cards that tickles this bug, and
this just keeps us from panicing. It doesn't actually fix the problem
(that will happen once I figure out why some cards hate the address
their CIS is mapped to high memory).

like we have on other platforms. Move savectx() to <machine/pcb.h>.
A lot of files got these MD prototypes through the indirect inclusion
of <machine/cpu.h> and now need to include <machine/md_var.h>. The
number of which is unexpectedly large...
osf1_misc.c especially is tricky because szsigcode is redefined in
one of the osf1 header files. Reordering of the include files was
needed.
linprocfs.c now needs an explicit extern declaration.

A timecounter will be selected when registered if its quality is
not negative and no less than the current timecounters.
Add a sysctl to report all available timecounters and their qualities.
Give the dummy timecounter a solid negative quality of minus a million.
Give the i8254 zero and the ACPI 1000.
The TSC gets 800, unless APM or SMP forces it negative.
Other timecounters default to zero quality and thereby retain current
selection behaviour.
Sign extension happens after the shift, not before so that boundary
cases like 0x40000000 will not be caught properly.
Instead, right shift ndirty. It is guaranteed to be a multiple of 8.
While here, do some manual code motion and code commoning.
