Moving an SPI around doesn't require any extra work from the rest
of the stack, and specially not for MSI-generated SPIs.
It is then worth returning IRQ_SET_MASK_OK_DONE instead of
IRQ_SET_MASK_OK, and simplify the other irqchips that rely on
this behaviour (GICv2m and Marvell's ODMI controller).

This commits adds a new irqchip driver that handles the ODMI
controller found on Marvell 7K/8K processors. The ODMI controller
provide MSI interrupt functionality to on-board peripherals, much like
the GIC-v2m.

The driver stays the same but the initialization changes a bit.
For OF boards we now get the memory map from the OF node and use
a linear mapping instead of the legacy mapping. For legacy boards
we still use a legacy mapping and just pass down all the parameters
from the board init code.

The irq-armada-370-xp driver can only be built for ARM 32 bits. The mvebu
family had grown with a new ARM64 SoC which will also select the
ARCH_MEVBU configuration. Since "ARM: mvebu: use the ARMADA_370_XP_IRQ
option", the ARM32 mvebu SoC directly select this new option. Selecting
it by default when ARCH_MEVBU is selected is no more needed.
This patch removes this dependency, thanks to this, a kernel for ARM64
mvebu SoC can be built without error due this driver.

Now that there is a ARMADA_370_XP_IRQ option to enable the irqchip
driver for Armada 370, XP, 375, 38x and 39x, let's select this option
when needed. Note that this selection is currently not mandatory
because ARMADA_370_XP_IRQ is for now always enabled when ARCH_MVEBU=y,
but this is something that we will change in the future, and therefore
we should make the relevant platforms select ARMADA_370_XP_IRQ when
needed.
Due to this, selecting GENERIC_IRQ_CHIP is no longer needed.

This commit moves the irq-armada-370-xp driver from using the
PCI-specific MSI infrastructure to the generic MSI infrastructure, to
which drivers are progressively converted.
In this hardware, the MSI controller is directly bundled inside the
interrupt controller, so we have a single Device Tree node to which
multiple IRQ domaines are attached: the wired interrupt domain and the
MSI interrupt domain. In order to ensure that they can be
differentiated, we have to force the bus_token of the wired interrupt
domain to be DOMAIN_BUS_WIRED. The MSI domain bus_token is
automatically set to the appropriate value by
pci_msi_create_irq_domain().

This allows this option to select other interrupt-related Kconfig

such selects done from arch/arm/mach-<foo>/.

Pull btrfs fixes from Chris Mason:
"Dave had a small collection of fixes to the new free space tree code,
one of which was keeping our sysfs files more up to date with feature
bits as different things get enabled (lzo, raid5/6, etc).
I should have kept the sysfs stuff for rc3, since we always manage to
trip over something. This time it was GFP_KERNEL from somewhere that
is NOFS only. Instead of rebasing it out I've put a revert in, and
we'll fix it properly for rc3.
Otherwise, Filipe fixed a btrfs DIO race and Qu Wenruo fixed up a
use-after-free in our tracepoints that Dave Jones reported"

in the cpufreq core (Viresh Kumar).
