BULK traffic. Make sure we don't ask for data in the last

keyboards connected to the RPI-B.

hypervisor. Apparently, hypervisors failed to filter out 'Standard
Extended Features' report from CPUID, but deliver #gp when
corresponding bit in %cr4 is toggled.
This shall be reconsidered later, after hypervisors correct the bug.

This is primarily for the TX EDMA and TX EDMA completion. I haven't yet
tied it into the EDMA RX path or the legacy TX/RX path.
Things that I don't quite like:
* Make the pointer type 'void' in ath_softc and have if_ath_alq*()
return a malloc'ed buffer. That would remove the need to include
if_ath_alq.h in if_athvar.h.
* The sysctl setup needs to be cleaned up.
I'm using this to debug EDMA TX and RX descriptors and it's really helpful
to have a non-printf() way to decode frames.
I won't link this into the build until I've tidied it up a little more.
This will eventually be behind ATH_DEBUG_ALQ.
kernel memory leakage to userspace. For the typical use, when a
filesystem put on the md disk, the change only results in CPU and
memory bandwidth spent to zero the page, since filsystems make sure
that user never see unwritten content. But if md disk is used as raw
device by userspace, the garbage is exposed.

to further reduce latency for threads in this queue. This should help
as threads transition from realtime to timeshare. The latency is
bound to a max of sched_slice until we have more than sched_slice / 6
threads runnable. Then the min slice is allotted to all threads and
latency becomes (nthreads - 1) * min_slice.

solve power loss problems with dishonest write caches. However, it
should improve the situation and force a full fsck when it is unable
to resolve with the journal.
- Resolve a case where the journal could wrap in an unsafe way causing
us to prematurely lose journal entries in very specific scenarios.

on timing of the operations and not real lookup, bringing too many
false positives. Remove the whole mechanism. If it needs to be
implemented, next time it should really be done in the proper way.
- Fix VOP_GETATTR() in order to cope with userland bugs that would
change the type of file and not panic. Instead it gets the entry as
if it is not existing.

There is one known issue: Some probes will display an error message along the
lines of: "Invalid address (0)"
I tested this with both a simple dtrace probe and dtruss on a few different
binaries on 32-bit. I only compiled 64-bit, did not run it, but I don't expect
problems without the modules loaded. Volunteers are welcome.

default compiler. This has two parts:
- Make sys/boot/pc98/boot2 always build with gcc for now, until we can
figure out a way to shrink it enough when building with clang.
- Since sys/boot/p98/cdboot uses .code16 directives, which are not yet
supported by clang's integrated assembler, use -no-integrated-as,
similar to sys/boot/i386/cdboot.

rewrite the way states from pfsync are merged into the local state tree
and the conditions on which pfsync will notify its peers on a stale update.
each side (ie, the sending and receiving side) of the state update is
compared separately. any side that is further along than the local state
tree is merged. if any side is further along in the local state table, an
update is sent out telling the peers about it.
case keys had already been freed. If encountering such state, then
just release last reference.
Not sure this can happen as a runtime race, but can be reproduced by
the following scenario:
- enable pfsync
- disable pfsync
- wait some time
- enable pfsync
