Linus Torvalds 714d8e7e27 arm64 updates for 4.1:
The main change here is a significant head.S rework that allows us to
 boot on machines with physical memory at a really high address without
 having to increase our mapped VA range. Other changes include:
 
 - AES performance boost for Cortex-A57
 - AArch32 (compat) userspace with 64k pages
 - Cortex-A53 erratum workaround for #845719
 - defconfig updates (new platforms, PCI, ...)

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

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.

  Other changes include:

   - AES performance boost for Cortex-A57
   - AArch32 (compat) userspace with 64k pages
   - Cortex-A53 erratum workaround for #845719
   - defconfig updates (new platforms, PCI, ...)"

Linus Torvalds d5935b07da ARM64: SoC changes for 3.18
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.

Mark Brown 49d947face arm64: configs: Enable X-Gene SATA and ethernet in 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.

Will Deacon af9b99647c arm64: defconfig: add virtio support for running as a kvm guest
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.

Will Deacon 74d2eb3cdb arm64: defconfig: enable a few more common/useful options in defconfig
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.

Mark Rutland 55834a773f arm64: defconfig: Expand default enabled features
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

Ramkumar Ramachandra 4eb507b874 arm64: include VIRTIO_{MMIO,BLK} in defconfig
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.
