For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.
The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.

The parser supports multiple pins, different GPIO controllers and can use
arbitrary names for the property (to match the many linux variants:
cd-gpios, power-gpios, wp-gpios, etc.).
Pass the driver name on ofw_gpiobus_add_fdt_child(). Update gpioled to
match.
An usage example of ofw_gpiobus_parse_gpios() will follow soon.
x2APIC mode is detected and enabled. Current theory is that switching
the APIC mode while an IPI is in flight might be the issue.
Postpone switching to x2APIC mode until we are guaranteed that all
starting IPIs are already send and aknowledged. Use aps_ready signal
as an indication that the BSP is done with us.

Do not ever return doomed vnode from lookup. This could happen, if
not checked, since dvp is relocked in the 'looking up ourselves' case.
In the other case, since dvp is relocked, mount point might go away
while fdesc_allocvp() is called. Prevent the situation by doing
vfs_busy() before unlocking dvp. Reuse the vn_vget_ino_gen() helper.

The DS3231 has an integrated temperature-compensated crystal oscillator
(TXCO) and crystal.
DS3231 has a temperature sensor, an independent 32kHz output (which can be
turned on and off by the driver) and another output that can be used as
interrupt for alarms or as a second square-wave output, which frequency and
operation mode can be set by driver sysctl(8) knobs.

The optimization made in r239940 is valid for struct mbuf's current structure
and size in FreeBSD, but hardcodes assumptions about sizes of struct mbuf,
which are unfortunately broken if additional data is added to the beginning of
struct mbuf
X-MFC note (discussed with rwatson):
This change requires the MPKTHSIZE definition, which is only available after
head@r277203 and will not be MFCed as it breaks mbuf(9) KPI.
A direct commit to stable/10 and merges to other branches to add the necessary
definitions to work with the code as-is will be done to facilitate this MFC

currently a spin lock. Apparently, the only reason for this is that
umtx_thread_exit() is called under the process spinlock, which put the
requirement on the umtx_lock. Note that the witness static order list
is wrong for the umtx_lock, umtx_lock is explicitely before any thread
lock, so it is also before sleepq locks.
Change umtx_lock to be the sleepable mutex. For the reason above, the
calls to umtx_thread_exit() are moved from thread_exit() earlier in
each caller, when the process spin lock is not yet taken.

This will override the resource allocation of simplebus, and also
merge the resource allocation code which was in xlp_pci.c.
With this change the SoC devices that does not have proper PCI
resources will be on the FDT simplebus. We can remove
sys/mips/nlm/dev/cfi_pci_xlp.c and sys/mips/nlm/dev/uart_pci_xlp.c
tracking.
It is important to subtract the residual from the requested
transfer size to see how much data was actually transferred. With
tape drives in particular, it is common to request more data than is
returned.
Also, add I/O latency tracking for CAM requests issued by
cam_periph_runccb().
If the caller supplies a struct devstat, and the I/O is a SCSI or
ATA I/O, we will track the elapsed time to provide I/O latency
statistics for the request.
sys/cam/scsi/cam_periph.c:
In cam_periph_runccb(), subtract the residual when reporting I/O
totals to devstat(9) for SCSI and ATA passthrough requests.
In cam_periph_runccb(), grab the I/O start time and supply
the start time to devstat_end_transaction() so that it can
calculate the elapsed I/O time.

This changes the tweak we give to the load from -32..31 to be 0..31
which seems more inline with the rest of the code (- rnd and the -=
64). It should also provide the randomness we need, and may fix a
signedness bug in the old code (it isn't clear that the effect was
intentional as opposed to sloppy, and the right shift of a signed
value is undefined to boot).
This stores sched_balance() behavior when it used random().
