b109dd74fe - Export HZ value via kern.hz sysctl (this is the same name as for the
loader tunable).
- Document other sysctls in this file and also mark them as loader tunable

0352f67204 - Remove the BUS_HANDLE_MIN checking in the __BUS_DEBUG_ACCESS macro;
for UPA it should have fulfilled its purpose by now and Fireplane-
  and JBus-based machines are way to messy in organization to implement
  something equivalent.
- Fix a bunch of style(9) bugs.

a384947e92 Fix panic and breakage for non-DMA ATA devices e.g. powermac macio cells.
Handle cases where dma function pointers may be NULL, and where
the max_iosize can't be derived from a DMA data structure. For
the latter, revert to the prior behaviour of using DFLTPHYS for
the max i/o size when there is no other data.

9fc852229b The BCE chips appear to have an undocumented requirement that RX frames be
aligned on an 8 byte boundary.  Prior to rev 1.36 this wasn't a problem
because mbuf clusters tend be naturally aligned.  The switch to using
split buffers with the first buffer being the embedded data area of the
mbuf has broken this assumption, at least on i386, causing a complete
failure of RX functionality.  Fix this for now by using a full cluster for
the first RX buffer.  A more sophisticated approach could be done with the
old buffer scheme to realign the m_data pointer with m_adj(), but I'm also
not clear on performance benefits of this old scheme or the performance
implications of adding an m_adj() call to every allocation.

688b98135c Add a new witness sysctl which returns the relations between any lock
and its children in the form:
"parent","child"
so that head and bottom of an oriented graph can be easilly detected and
various form of diagrams can be build.
The sysctl is called debug.witness.graphs and it is read-only; in order
to get the list of relations, a simple:
#sysctl debug.witness.graphs
will do the trick.

This approach has been choosen in order to support easilly things like
the DOT format and such.  Soon, an auto-explicative awk script, which
filters simple informations returned by the sysctl and converts them into
a real DOT script, will be committed to the repository between examples.

083b2bd41a - Use the name returned by device_get_nameunit(9) for the name of the
counter-timer timecounter so the associated SYSCTL nodes don't clash on
  machines having multiple U2P and U2S bridges as well as establishing a
  clear mapping between these bridges and their timecounter device.
- Don't bother setting up a "nice" name for the IOMMU, just use the name
  returned by device_get_nameunit(9), too.
- Fix some minor style(9) bugs.
- Use __FBSDID in counter.c

be00f6053b Fix a few edge cases with error handling in cpufreq(4)'s CPUFREQ_GET()
method:
- If the last of the child cpufreq drivers returns an error while trying to
  fetch its list of supported frequencies but an earlier driver found the
  requested frequency, don't return an error to the caller.
- If all of the child cpufreq drivers fail and the attempt to match the
  frequency based on 'cpu_est_clockrate()' fails, return ENXIO rather than
  returning success and returning a frequency of CPUFREQ_VAL_UNKNOWN.

4f0794ff96 Use a better approach to force the interrupt which should work for
all cards/modes.
In addition to the intr forcing added with rev. 1.205 adopt the other
places to use the same logic.

We need to exclude a few chips/revisions (5700, 5788) from using the
enhanced version and fall back to the old way as that is the only
method they support.

43d7128c14 Expand kdb_alt_break a little, most commonly used with the option
ALT_BREAK_TO_DEBUGGER.  In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).

We've used variations of this at work.  The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.

The reboot request is a safer way of getting into single user than
a power cycle.  eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.

I've taken my best guess at what the !x86 and non-sio code changes
should be.

This also makes sio release its spinlock before calling KDB/DDB.

60e2edce55 sync_vnode() has some messy code about locking in order to deal with
mount fs needing Giant to be held when processing bufobjs.
Use a different subqueue for pending workitems on filesystems requiring
Giant. This simplifies the code notably and also reduces the number of
Giant acquisitions (and the whole processing cost).
