The amount of available memory is clearly a board-specific value, so
the core per-soc dtsi should not define a default of any sort.
Therefore move the memory-nodes to the two board files.

Also fix the amount of memory on Kylin (512MB instead of 1GB).
While in most cases the bootloader will override this with the
actual amount of memory, there is no need to keep known wrong values
in the board-dts.

Pinky boards don't have the hotplug pin connected. So remove the
hotplug pinctrl setting and enable the force-hpd option, to allow
them to find the display too.

While on speedy boards, the hotplug pin is connected, judging by comments
in a chromeos change it seems the "panels HPD voltage is too low to be
detected", so it also needs the forced hotplug, as we of course also know
that a display is connected.

This patch adds the thermal needed main information for rk3228 SoCS.

Basically has the following content:

1) TSADC controller:
Add the needed attributes for rk3036 TSADC controller.

Especially for the TSHUT, in some cases if we are unable to shut it down
in orderly fashion (says: kernel is stuck holding a lock or similar), then
hardware TSHUT will reset it.
If the temperature is over 95C over a period of time the thermal shutdown
of the tsadc is invoked with can either reset the entire chip via the CRU,
or notify the PMIC via a GPIO. This should be set in the specific board.

2) Thermal zones:
Add the needed device mode for thermal generic framework.

Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"

Commit 0b81d077 ("fs crypto: move per-file encryption from f2fs
tree to fs/crypto") moved the f2fs crypto files to fs/crypto/ and
renamed the symbol prefixes from "f2fs_" to "fscrypt_" (and from "F2FS_"
to just "FS" for preprocessor symbols).

Because of the symbol renaming, it's a bit hard to see it as a file
move: use

    git show -M30 0b81d077

to lower the rename detection to just 30% similarity and make git show
the files as renamed (the header file won't be shown as a rename even
then - since all it contains is symbol definitions, it looks almost
completely different).

Even with the renames showing as renames, the diffs are not all that
easy to read, since so much is just the renames.  But Eric Biggers
noticed that it's not just all renames: the initialization of the
xts_tweak had been broken too, using the inode number rather than the
page offset.

That's not right - it makes the xfs_tweak the same for all pages of each
inode.  It _might_ make sense to make the xfs_tweak contain both the
offset _and_ the inode number, but not just the inode number.
