89d798b73d ARM: 8487/1: Remove IPI_CALL_FUNC_SINGLE
Since 9a46ad6d6df3 ("smp: make smp_call_function_many() use logic
similar to smp_call_function_single()"), the core IPI handling
has been simplified, and generic_smp_call_function_interrupt is
now the same as generic_smp_call_function_single_interrupt.

This means that one of IPI_CALL_FUNC and IPI_CALL_FUNC_SINGLE has
become redundant. We can then safely drop IPI_CALL_FUNC_SINGLE,
and use only IPI_CALL_FUNC.

This has the advantage of reducing the number of SGI IDs we're using
(a fairly scarse resource).

Tested on a dual A7 board.

f6419f240b ARM: 8485/1: cpuidle: remove cpu parameter from the cpuidle_ops suspend hook
The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.

This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

a67c7129d4 Defconfig (exynos and multi_v7) changes for Exynos based boards for 4.5:
1. Enable Maxim 8997 and 77693 family drivers (charger, extcon, LED,
    RTC, haptic/motor, regulator).
 2. Build ChromeOS EC drivers as modules on multi_v7.
 3. Enable drivers important for Exynos4210-based Universal C210 board.
 4. Enable NFSv4 client.
 5. On exynos_defconfig set some options to a value recommended
    by systemd. This also makes it more consistent with multi_v7.

12ec938403 ARM: dts: sun5i: Add dts file for the Empire Electronix D709 tablet
The Empire Electronix D709 tablet is a fairly standard 7" A13 tablet,
featuring usb-wifi, a micro-sd slot, micro-usb otg and headphone jack.

Empire Electronix is written on the back of the tablet, the D709 model
info can be found in the about tablet menu in android.

The PCB has no markings to speak of.

This dts file does not add support for the ft5x touchscreen found at
i2c bus 1, addr 0x38, irq PG11, because it does not work out of the box.
It seems it has been flashed with the wrong firmware and needs to have
alternative firmware uploaded at boot to make the touchscreen work
properly, when hot-booting from android into an upstream kernel the
touchscreen does work.

The Memsic MXC622X accelerometer at i2c bus 1, addr 0x15 also is not
enabled as there is no driver for it.

The realview multiplatform series has a trivial conflict with
one of the treewide cleanups, let's just merge that in to
avoid having to resolve this later.

* treewide/cleanup:
  ARM: use "depends on" for SoC configs instead of "if" after prompt
  ARM/clocksource: use automatic DT probing for ux500 PRCMU
  ARM: use const and __initconst for smp_operations
  ARM: hisi: do not export smp_operations structures

The platsmp-dt.c file does not build when CONFIG_SMP is disabled:

This changes the Makefile to build it conditionally on CONFIG_SMP.
The legacy platsmp.c file is only used for ATAGS based builds, so
we can move it into the CONFIG_ATAGS conditional.

Merge tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/multiplatform

Pull "Multiplatform support for the RealView" from Linus Walleij:

Here is the result of my application of the second part of Arnds
patchset, actually enabling multiplatform and getting the RealView
off the ground as a multiplatform target.

It is dependent on an outstanding patch to the irqchips tree bumping
the number of GICs to 2 for the RealView platform. I cannot say I will
be sleepless if these go in side by side: each branch will compile but
will not boot until both trees have been pulled hurting bisectability a
bit.

- Tested on the ARM PB11MPCore
- Tested with boardfile boot
- Tested with DeviceTree boot

This contains multiple trivial cleanups to the realview headers:

- removing the uncompress.h header that is unused
- removing the irqs.h header and NR_IRQS logic that is
  obsoleted by sparse IRQs

17d44d7d87 ARM: no longer make CPU targets visible separately
Now that realview and integrator always select the correct CPU
type themselves based on the core tiles, there is no need to
still have them user-visible in arch/arm/mm/Kconfig. The
ARM925T symbol has been selected by the only user for many
years, so that can be removed along with the realview and
integrator specific ones.

This also solves randconfig build problems on realview.

abc466951a ARM: integrator: use explicit core module options
For consistency with the other platforms, this remove the CPU
selection logic in mm/Kconfig that was only used by integrator,
and adds specific options for each available core tile and core
module, which in turn select the correct CPUs.

This is consistent with the new way that we do it for realview
and all other platforms.

c7da6fa43c arm/arm64: KVM: Detect vGIC presence at runtime
Before commit 662d9715840aef44dcb573b0f9fab9e8319c868a
("arm/arm64: KVM: Kill CONFIG_KVM_ARM_{VGIC,TIMER}") is was possible to
compile the kernel without vGIC and vTimer support. Commit message says
about possibility to detect vGIC support in runtime, but this has never
been implemented.

This patch introduces runtime check, restoring the lost functionality.
It again allows to use KVM on hardware without vGIC. Interrupt
controller has to be emulated in userspace in this case.

-ENODEV return code from probe function means there's no GIC at all.
-ENXIO happens when, for example, there is GIC node in the device tree,
but it does not specify vGIC resources. Any other error code is still
treated as full stop because it might mean some really serious problems.
