Andrew Lunn fef5c646db ARM: dts: vf610-zii-dev-c: Wire up PHY interrupts
The PHYs embedded in the switch direct there interrupts through the
switch interrupt controllers. Now that devel C has its switch
interrupts connected to the SoC, the PHY interrupts can be used by
phylib. Explicitly include MDIO nodes in the switch device tree nodes,
and link the PHY interrupts back to the switch interrupt
controller. Also, link the ports to the PHYs on the MDIO bus.

All currently supported i.MX25-based machines use phy_type = "utmi" and
dr_mode = "otg".  So this seems to be a sensible default.

This also doesn't hurt out-of-tree machines because up to now they had
to specify these two properties in the machine.dts which still takes
precedence by just overwriting the defaults added here.

Fabio Estevam 4480de8245 ARM: dts: imx53-qsb: Constrain the TVE DAC voltage
Quoting Philipp Zabel:
"Since this regulator is used as the TVDAC analog power supply, this
range should at least be limited to the analog power supply range of the
TVDAC, listed in Table 74-9. of the i.MX53 reference manual (2.5-2.75V).

But since the nominal voltage is 2.75V, which was used to determine the
analog gain that is supposed to result in the necessary 0.7V
peak-to-peak amplitude on the VGA output, I'd say we should just fix the
voltage to 2750000 here."

, so limit the TVDAC analog power supply as suggested.

Ingo Molnar c3edc4010e sched/headers: Move task_struct::signal and task_struct::sighand types and accessors into <linux/sched/signal.h>
task_struct::signal and task_struct::sighand are pointers, which would normally make it
straightforward to not define those types in sched.h.

That is not so, because the types are accompanied by a myriad of APIs (macros and inline
functions) that dereference them.

Split the types and the APIs out of sched.h and move them into a new header, <linux/sched/signal.h>.

With this change sched.h does not know about 'struct signal' and 'struct sighand' anymore,
trying to put accessors into sched.h as a test fails the following way:

  ./include/linux/sched.h: In function ‘test_signal_types’:
  ./include/linux/sched.h:2461:18: error: dereferencing pointer to incomplete type ‘struct signal_struct’
                    ^

This reduces the size and complexity of sched.h significantly.

Update all headers and .c code that relied on getting the signal handling
functionality from <linux/sched.h> to include <linux/sched/signal.h>.

The list of affected files in the preparatory patch was partly generated by
grepping for the APIs, and partly by doing coverage build testing, both
all[yes|mod|def|no]config builds on 64-bit and 32-bit x86, and an array of
cross-architecture builds.

Nevertheless some (trivial) build breakage is still expected related to rare
Kconfig combinations and in-flight patches to various kernel code, but most
of it should be handled by this patch.

Linus Walleij 332524eaf7 ARM: deconfig: fix the moxart defconfig
The moxart defconfig wasn't even building a kernel for Moxart,
it was building a kernel for V4T on the nothing platform. Switch
to MULTI_V4 and keep the right drivers, update a few selections.
Now it (presumably) builds a minimalist Moxart kernel again.

Linus Walleij 3131d970f0 ARM: ux500: resume the second core properly
The pen hold/release scheme was copied over to Ux500 from the ARM
reference designs like most of these at the time. It is not needed
at all, and was mostly removed in commit c00def71ef
"ARM: ux500: simplify secondary CPU boot".

However on the suspend/resume path and hot plug/unplug of CPUs,
the .cpu_die() callback was still waiting for the pen to be
released which made it spin forever and the second core never come
back online after suspend/resume.

Fix this by simply replacing the strange custom .cpu_die() with
a oneline wfi() just like e.g. the qcom platform does. This fixes
the issue and makes the second core come up properly after
suspend/resume.

As a side effect, this rids us of the completely surplus local
setup.h and hotplug.c files, and we just compile this into platsmp.c
with everything else SMP.

Ard Biesheuvel efa7cebdbf crypto: arm/crc32 - add build time test for CRC instruction support
The accelerated CRC32 module for ARM may use either the scalar CRC32
instructions, the NEON 64x64 to 128 bit polynomial multiplication
(vmull.p64) instruction, or both, depending on what the current CPU
supports.

However, this also requires support in binutils, and as it turns out,
versions of binutils exist that support the vmull.p64 instruction but
not the crc32 instructions.

So refactor the Makefile logic so that this module only gets built if
binutils has support for both.
