The Orangepi Plus has a 16GB eMMC, the vcc, the lack of pull-ups and
the use of the hw-reset pin have all been verified with the board
schematic.

With this dts node for mmc2, the eMMC runs at the following ios settings:
clock:          52000000 Hz
vdd:            21 (3.3 ~ 3.4 V)
bus mode:       2 (push-pull)
chip select:    0 (don't care)
power mode:     2 (on)
bus width:      3 (8 bits)
timing spec:    8 (mmc DDR52)
signal voltage: 0 (3.30 V)
driver type:    0 (driver type B)

Note the mmcblk1boot0/boot1 partitions are unused as the BROM will load
the SPL from 8k from the start of the main blockdev, just as with a
regular sdcard in mmc0.

The Orangepi Plus and Orangepi Plus 2 have a realtek rtl8189etv sdio
wifi chip. This commit adds a device-tree node to power it up, so
that the mmc subsys can scan it, and enables the mmc controller which
is connected to it.

Note that this just makes the wifi controller show up as a sdio device.
In order for it to work a compatible sdio driver is necessary, an out
of tree driver is available here:
https://github.com/jwrdegoede/rtl8189ES_linux/

Binding the driver is not done through device tree, but through sdio
vendor- and device-id, so it can safely be enabled in devicetree
without having a driver upstream yet.

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.
