Merging in the few patches I had kept separate from main next/dt, since others
got merged here directly.
* next/arm64:
arm64: defconfig: Enable PCI generic host bridge by default
arm64: Juno: Add support for the PCIe host bridge on Juno R1
Documentation: of: Document the bindings used by Juno R1 PCIe host bridge
arm64: dts: mt8173: Add clocks for SCPSYS unit
arm64: dts: mt8173: Add subsystem clock controller device nodes
+ Linux 4.3-rc5
CONFIG_CRYPTO_CRC32_ARM64 has been around since commit f6f203faa3
("crypto: crc32 - Add ARM64 CRC32 hw accelerated module") but defconfig
did not automatically enable it.

Freescale will be a spinning-out a set of ARMv8 based SoCs which
will be based on a similar overall SoC architecture. So, this patch
converts the existing infrastructure in the arm64/dts, arm64/Kconfig
and arm64/configs to use the generic convention ARCH_LAYERSCAPE
in place of the more specific FSL_LS2085A, to save code duplication
later-on.

We keep collecting defconfig updates in a separate branch mostly to encourage
people to handle them separately and avoid conflicts between different topics.
Most of these are enablement of new SoCs, boards or drivers that have
come in, or minor config refreshes due to reorderings in Kconfig
files, etc. I.e. mostly minor churn of various kinds.

The kernel memtest utility is incredibly useful for detecting memory
problems, but sadly isn't in defconfig.
The memtest itself is only run when the user has explicitly passed a
memtest option on the kernel command line, so simply enabling the option
should not have a negative impact.

Pull arm64 updates from Will Deacon:
"Here are the core arm64 updates for 4.1.
Highlights include a significant rework to head.S (allowing us to boot
on machines with physical memory at a really high address), an AES
performance boost on Cortex-A57 and the ability to run a 32-bit
userspace with 64k pages (although this requires said userspace to be
built with a recent binutils).
The head.S rework spilt over into KVM, so there are some changes under
arch/arm/ which have been acked by Marc Zyngier (KVM co-maintainer).
In particular, the linker script changes caused us some issues in
-next, so there are a few merge commits where we had to apply fixes on
top of a stable branch.

The usual defconfig tweaks, this time:
- FHANDLE and AUTOFS4_FS to keep systemd happy
- PID_NS, QUOTA and KEYS to keep LTP happy
- Disable DEBUG_PREEMPT, as this *really* hurts performance

This patch enables a few things missing from our defconfig:
- PCI and MSI, including support for the x-gene host controller
- BPF JIT
- SPI, GPIO and MMC for Seattle
- GPIO for x-gene
- USB for Juno
- RTC
It also removes HMC_DRV, which was being built as a module for some
reason.

Starting with 3.18, we are merging SoC-specific changes for arm64 through
the arm-soc tree, like we have been doing for arm32.
This time, there is only one set of changes, adding support for the
Cavium "Thunder" Soc family. Since the changes are relatively small,
this includes Kconfig, defconfig and DT changes.
If all goes well, we will never require adding actual C source code
for platform support in arm64, given that the architecture is more
clearly defined and we have moved out a lot of the platform specifics
into device drivers for arm32 already.

This patch enables Thunder SoCs in the arm64 defconfig. This is
esp. useful to add Thunder platforms to automated builds based on
arm64 defconfig.

Currently when run on an APM platform the ARMv8 defconfig has no viable
options for rootfs other than ramdisk which is rather limiting. Since
we already have both SATA and the bits needed for NFS root enabled we just
need to enable the relevant drivers so do that, helping enable direct
testing of upstream.
If the configuration ends up becoming too big we can consider modularising
some of the drivers and asking people to use an initramfs but for now this
is not an issue.

When running as a kvm guest on a para-virtualised platform, it is useful
to have virtio implementations of console, 9pfs and network.
This adds these options to the arm64 defconfig, so we can easily run a
defconfig kernel build as both host and as a kvm guest.

Whilst our defconfig is certainly usable, there are a few extra features
we can enable to make it considerably more useful, particularly if
people are using it for testing:
- KVM
- SWAP
- Hugepages
- ARMv8 crypto
This patch enables these options in our defconfig. Note that the ordering
has changed slightly, since this is the result of a new savedefconfig
make target.

FPGA implementations of the Cortex-A57 and Cortex-A53 are now available
in the form of the SMM-A57 and SMM-A53 Soft Macrocell Models (SMMs) for
Versatile Express. As these attach to a Motherboard Express V2M-P1 it
would be useful to have support for some V2M-P1 peripherals enabled by
default.
Additionally a couple of of features have been introduced since the last
defconfig update (CMA, jump labels) that would be good to have enabled
by default to ensure they are build and boot tested.
This patch updates the arm64 defconfig to enable support for these
devices and features. The arm64 Kconfig is modified to select
HAVE_PATA_PLATFORM, which is required to enable support for the
CompactFlash controller on the V2M-P1.
A few options which don't need to appear in defconfig are trimmed:
* BLK_DEV - selected by default
* EXPERIMENTAL - otherwise gone from the kernel
* MII - selected by drivers which require it
* USB_SUPPORT - selected by default

Currently, development on arm64 is aided by a Foundation_v8 emulator
distributed by ARM [1]. To run their kernels, users will execute:
$ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs
To mount the raring-rootfs filesystem, the kernel parameter should
typically include:
root=/dev/vda
For this device to be present, the kernel must be compiled with
VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the
default configuration.

The Kconfig entry for DEBUG_ERRORS is a verbatim copy of the former arm

actually used anywhere. There are still no users of DEBUG_ERRORS so
