3cb920a151 ARM: ux500: Apply tc3589x's GPIO/IRQ properties to HREF's DT
This patch ensures the tc3589x and tc3598x-gpio devices are
rightfully given interrupt controller status. We also describe
the tc3598x-gpio GPIO expander in full and specify it as a GPIO
controller. Finally we reference that the external MMC slot's
Card Detection GPIO on the HREF is located on the tc3598x-gpio
expander.

39b740bf14 ARM: ux500: Rename MSP board file to something more meaningful
The 'msp' board file does more than just register MSP devices. It
also registers some other components necessary to get audio working
on ux500 based platforms; such as the PCM and Machine Drivers. For
that reason we're changing the filename to be more encompassing -
'audio'.

d524fa7ff6 ARM: ux500: Add i2c configurations to the Device Tree for DB8500 based devices
Since initial support was provided for the Nomadik I2C driver, it
has been converted to an AMBA device. AMBA devices are probed in
a slightly different way to other devices, so we have to identify
them using an "arm,primecell" compatible string. As well as doing
just that, this patch specifies which regulators the controller
should use and requests a clock-speed. The latter is provided as
more of an example, as it's the same as the recently changed
default configuration.

e9edfe1ec0 Revert "input: ab8500-ponkey: Create AB8500 domain IRQ mapping"
This reverts commit ca3b3faf9b.

There was a plan to place ab8500_irq_get_virq() calls in each AB8500
child device prior to requesting an IRQ, but as we're no longer using
Device Tree to collect our IRQ numbers, it's actually better to allow
the core to do this during device registration time. So the IRQ number
we pull from its resource has already been converted to a virtual IRQ.

8d4c6d45bc ARM: ux500: Force AB8500 to use the GIC as its interrupt controller
It's understood that the AB8500 should be subordinate to the DB8500;
however, the AB8500 uses the GIC as it's interrupt controller. If
we do not specify which IRQ controller to use the default is to use
the next encountered IRQ controller as we climb the tree. This would
be the DB8500. This patch ensures the AB8500 makes use of the correct
interrupt controller.

62861095dc of/irq: Create stub for of_irq_find_parent when !CONFIG_OF
of_irq_find_parent is a handy function to use outside the confines of
the Open Firmware subsystem. One such use-case is when the IRQ Domain
wishes to find an IRQ domain for a given device node. Currently it can
not take any notice of the 'interrupt-parent' property. Instead it
just uses the first IRQ controller as it climbs the Device Tree. If
we were to use this as a precursor the resultant controller is more
likely to be correct.

37407ea7f9 Revert "sched: Improve scalability via 'CPU buddies', which withstand random perturbations"
This reverts commit 970e178985.

Nikolay Ulyanitsky reported thatthe 3.6-rc5 kernel has a 15-20%
performance drop on PostgreSQL 9.2 on his machine (running "pgbench").

Borislav Petkov was able to reproduce this, and bisected it to this
commit 970e178985 ("sched: Improve scalability via 'CPU buddies' ...")
apparently because the new single-idle-buddy model simply doesn't find
idle CPU's to reschedule on aggressively enough.

Mike Galbraith suspects that it is likely due to the user-mode spinlocks
in PostgreSQL not reacting well to preemption, but we don't really know
the details - I'll just revert the commit for now.

There are hopefully other approaches to improve scheduler scalability
without it causing these kinds of downsides.

0848c94fb4 mfd: core: Push irqdomain mapping out into devices
Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.
