7eee820140 Change the sysctl naming for the old and new NFS clients
to vfs.oldnfs.xxx and vfs.nfs.xxx respectively. This makes
the default nfs client use vfs.nfs.xxx after r221124.

4675dfde1b Add a sysctl kern.geom.part.check_integrity for those who has corrupt

Also unhide an error message from bootverbose, this would help to

a58fc6f0fd Only update the scheduler's byte count table for aggregation queues.
The other queues, especially the command queue, uses the FIFO mode
which doesn't require the byte count table because queued entries are

ca9749fa32 Fix NF calibration breakage introduced by me in a past commit.
Since the returned NF will be -ve, checking for <= 0 is not good
enough. For now, check whether it equals 0 or -1; a future commit

8f1059ecb5 Prefer switching the memory stack from user to kernel *before* switching
the register stack. While the ordering doesn't matter, it creates an
invariant not previously there: the memory stack pointer will always be
larger than the register stack pointer. With this invariant in place,
it's easier to add instrumentation code that detects a stack overflow
because in such a scenario the memory stack pointer and register stack
pointers have crossed each other.

Aside: basic kernel operation needs about half the stack size (~16K)
at most. We have plenty of head room on the kernel stack...

dce7f91629 Sharpening the saw:
o   Clobber the register that holds the restart token immediately after
    crossing the restart point. This prevents false positives (i.e. a
    nested exception that we don't know can happen and that is being
    treated as one we know by virtue of a lingering restart token).
o   Now that the bootstrap kernel stack is free, switch onto it and call
    trap() for nested traps that we don't know about. In trap we panic()
    so that we can analyze the condition.

d8ffb23a02 Import initial EEPROM code for Kite (AR9287).
I've tested this locally and it does indeed read and attach to an AR9287
EEPROM. But a lot more code needs to be ported over to the HAL before
the AR9287 is functional.

I'm importing this separate from the rest of the codebase (and unlinked from
the build for now) in case someone wishes to begin fiddling with porting
the rest of the code over from Linux ath9k.

d37f1bd21e gcc and clang semantics imply certain -mno-* flags when other certain -mno-*
flags are also specified. This change makes use of this behaviour and removes
unneeded -mno-* flags.

Note that clang does not yet enable AVX support for any CPU. However at some
point in the future it will and since we definitely want to disable it for the
kernel, we might as well add the -mno-avx flag now.

c3c15582fd When disabling RIFS for Sowl (AR9160) and Howl (AR9130), make sure RIFS
is totally disabled.

The Atheros HAL code does this for Sowl/Howl but not for Owl (AR5416) where
RIFS is disabled by default.

This seems to quieten the occasional baseband hang I've been seeing with
the AR9160 in STA mode under constant heavy traffic load.

3d3b036f95 Move the ZERO_REGION_SIZE to a machine-dependent file, as on many
architectures (i386, for example) the virtual memory space may be
constrained enough that 2MB is a large chunk.  Use 64K for arches
other than amd64 and ia64, with special handling for sparc64 due to
differing hardware.

Also commit the comment changes to kmem_init_zero_region() that I
missed due to not saving the file.  (Darn the unfamiliar development
environment).

1881f29e6e Refactor Xen PV code to use new event timers subsystem. That uses one-shot
Xen timer and time counter to provide one-shot and periodic time events.

On my tests this reduces idle interruts rate down to about 30Hz, and accor-
ding to Xen VM Manager reduces host CPU load by three times comparing to
the previous periodic 100Hz clock. Also now, when needed, it is possible to
increase HZ rate without useless CPU burning during idle periods.

Now only ia64 and some ARMs left not migrated to the new event timers.
