DWC OTG driver. Fix a hang issue when using LOW and FULL speed
BULK traffic. Make sure we don't ask for data in the last
microframe. This allows using devices like USB mice and USB
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.
* The last character is not displayed.
* If the alias ends with itself (as a word), an infinite memory-eating loop
occurs.
If an alias is defined initially, a space is appended to avoid recursion but
this did not happen when an alias was later modified.

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.

sorting order for time and name with the -t option. IEEE Std 1003.2
(POSIX.2) mandates that the -t option sort in descending order, and
that if two files have the same timestamp, they should be sorted in
ascending order of their names. The -r flag reverses both of these
sort orders, so they're never the same. This creates significant
problems for sequentially named files stored on FAT file systems,
where it can be impossible to list them in the order in which they
were created.
Add , (comma) option to print file sizes grouped and separated by
thousands using the non-monetary separator returned by localeconv(3),
typically a comma or period.

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.
