Pull arch signal handling cleanup from Richard Weinberger:
"This patch series moves all remaining archs to the get_signal(),
signal_setup_done() and sigsp() functions.
Currently these archs use open coded variants of the said functions.
Further, unused parameters get removed from get_signal_to_deliver(),
tracehook_signal_handler() and signal_delivered().
At the end of the day we save around 500 lines of code."

Pull driver core updates from Greg KH:
"Here's the big driver-core pull request for 3.17-rc1.
Largest thing in here is the dma-buf rework and fence code, that
touched many different subsystems so it was agreed it should go
through this tree to handle merge issues. There's also some firmware
loading updates, as well as tests added, and a few other tiny changes,
the changelog has the details.
All have been in linux-next for a long time"

Conflicts:
drivers/base/platform.c
A number of board files in arch/arm and arch/unicore32
explicitly reference platform_bus device as a parent
for new platform devices.
This is unnecessary, as platform device API guarantees
that devices with NULL parent are going to by adopted
by the mentioned "root" device.
This patch removes or replaces with NULL such references.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on unicore32 platforms.

Pull USB driver updates from Greg KH:
"Here is the big USB driver pull request for 3.16-rc1.
Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work
better now that it has been reworked to do per-port power control
dynamically. There's also a raft of gadget driver updates and fixes,
CONFIG_USB_DEBUG is finally gone now that everything has been
converted over to the dynamic debug inteface, the last hold-out
drivers were cleaned up and the config option removed. There were
also other minor things all through the drivers/usb/ tree, the
shortlog shows this pretty well.
All have been in linux-next, including the very last patch, which came
from linux-next to fix a build issue on some platforms"

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures. Make pcibios_penalize_isa_irq() a
__weak function to simplify the code. This removes the need for new
platforms to add stub implementations of pcibios_penalize_isa_irq().
