Fix the AR724x PCIe glue to correctly probe the BAR on AR7240 devices.
There's a bug in the AR7240 PCIe hardware where a correct BAR will end
up having the device disappear.
It turns out that for the device address it should be all 0's.
However, this meant that the PCI probe code would try writing 0xffffffff
in to see how big the window was, read back 0x0, and think the window
was 32 bits. It then ended up calculating a resource size of 0 bytes,
failed to find anything via an rman call, and this would fail to attach.
I have quite absolutely no idea how in the various planes of existence
this particular bit of code and how it worked with the PCI bus code
ever worked. But, well, it did.
Update the usage message and the man page to account for the new long
options. Bump the version number to 20140927.
While here, use explicit fputc() calls to skip a line in the output.
This to avoid having to hunt for extra '\n' characters in the printf
format strings.
Disable the makeoption with MFS_IMAGE= set as we don't ship that file
and it thus breaks the default build. You can still use various other
ways (tools) to embedd the image after the kernel build.

Do not pass whole descriptor block size as align to fwdma_malloc_multiseg
Do not pass wrong alignment value to fwdma_malloc_multiseg and ultimately
to contigalloc. In addition to being wrong, this causes insta-panic in
certain cases due to safety assertion - the alignment is required to be
the power of two and the value we calculate here seldom is.

Allow the PIC's IMR register to be read before ICW initialisation.
As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.
The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.
With this change, Linux kernels 3.15-rc2 and later won't hang
on boot when calibrating the local APIC.
Make sure the adapter's management queue and the event queue are
available before any uppper layer driver (TOE, iWARP, or iSCSI)

Prior to this commit, primes(6) relied solely on sieving with primes up
to 65537, with the effect that composite numbers which are the product
of two non-16-bit primes would be incorrectly identified as prime. For
example,
# primes 10995116278001099511627820
would output 1099511627803 1099511627807 1099511627813
when in fact only the first of those values is prime.
This commit adds strong pseudoprime tests to validate the candidates
which pass the initial sieving stage, using bases of 2, 3, 5, 7, 11,
13, 17, 19, and 23. Thanks to papers from C. Pomerance, J.L. Selfridge,
and S.S. Wagstaff, Jr.; G. Jaeschke; and Y. Jiang and Y. Deng, we know
that the smallest value which passes these tests is 3825123056546413051.
At present we do not know how many strong pseudoprime tests are required
to prove primality for values larger than 3825123056546413050, so we
force primes(6) to stop at that point.

Fix fcntl(2) compat32 after r270691. The copyin and copyout of the

The VFS_UNMOUNT() methods for UFS and tmpfs try to establish

prevents namei() from stepping over the mount point. The thread doing

Replace multiple nearly-identical copies of code to walk through an FDT
node's interrupts=<...> property creating resource list entries with a
single common implementation. This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.
This also adds handling of the interrupts-extended property, which allows
specifying multiple interrupts for a node where each interrupt can have a
separate interrupt-parent. The bindings for this state that the property
cells contain an xref phandle to the interrupt parent followed by whatever
interrupt info that parent normally expects. This leads to having a
variable number of icells per interrupt in the property. For example you
could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.
