soc: renesas: rcar-sysc: Enable Clock Domain for I/O devices
On R-Car H3, some power areas (e.g. A3VP) contain I/O devices, which are
also part of the CPG/MSSR Clock Domain.
On all R-Car SoCs, devices in the "always-on" PM Domain are part of the
Clock Domain served by the CPG/MSSR or CPG/MSTP driver.
Hook up the CPG/MSTP or CPG/MSSR Clock Domain attach/detach callbacks to
enable power management using module clocks. Which callback to hook up
depends on the presence of device nodes compatible with
"renesas,cpg-mstp-clocks". This clears the path for a future migration
from the CPG/MSTP to the CPG/MSSR driver on R-Car H1 and
Gen2.

The SYSCIER and SYSCIMR register values are derived from the power areas

Initialization is done from an early_initcall(), to make sure the PM

The R-Car SYSC PM Domain driver has to power manage devices in power
areas using clocks. To reuse code and to share knowledge of clocks
suitable for power management, this is ideally done through the existing
cpg_mssr_attach_dev() and cpg_mssr_detach_dev() callbacks.
Hence these callbacks can no longer rely on their "domain" parameter
pointing to the CPG/MSSR Clock Domain. To handle this, keep a pointer to
the clock domain in a static variable. cpg_mssr_attach_dev() has to
support probe deferral, as the R-Car SYSC PM Domain may be initialized,
and devices may be added to it, before the CPG/MSSR Clock Domain is
initialized.
Dummy callbacks are provided for the case where CPG/MSTP support is not
included, so the rcar-sysc driver won't have to care about this.
clk: renesas: mstp: Provide dummy attach/detach_dev callbacks
Provide dummy cpg_mstp_{at,de}tach_dev() PM Domain callbacks if CPG/MSTP
support is not included, so the rcar-sysc driver won't have to care
about this.
clk: renesas: Provide Kconfig symbols for CPG/MSSR and CPG/MSTP support
Currently the decision whether to build the renesas-cpg-mssr and
clk-mstp drivers is handled by Makefile logic. However, the rcar-sysc
driver will need to know whether CPG/MSSR and/or CPG/MSTP support are
available or not.
To avoid having to duplicate this logic, move it to Kconfig. Provide
non-visible CLK_RENESAS_CPG_MSSR and CLK_RENESAS_CPG_MSTP Kconfig
symbols, which can be used by both Makefiles and C code.
ARM: dts: r8a7779: Correct interrupt type for ARM TWD
The ARM TWD interrupt is a private peripheral interrupt (PPI), and per

For R-Car H1 devices the PPI type cannot be set, and so when we attempt
to set the type for the ARM TWD interrupt it fails. This has gone
unnoticed because it fails silently, and because we cannot re-configure
the type it has had no impact. Nevertheless fix the type for the TWD

Merge tag 'ofs-pull-tag-1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux
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"
see Documentation/filesystems/orangefs.txt for more in-depth details.

f2fs/crypto: fix xts_tweak initialization
Commit 0b81d07790726 ("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
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.

NTB: Remove _addr functions from ntb_hw_amd
Kernel zero day testing warned about address space confusion. A virtual
iomem address was used where a physical address is expected. The
offending functions implement an optional part of the api, so they are
removed. They can be added later, after testing.

* switch orangefs_remount() to taking ORANGEFS_SB(sb) instead of sb
* remove from the list _before_ orangefs_unmount() - request_mutex
in the latter will make sure that nothing observed in the loop in
ORANGEFS_DEV_REMOUNT_ALL handling will get freed until the end
of loop
* on removal, keep the forward pointer and zero the back one. That
way we can drop and regain the spinlock in the loop body (again,
ORANGEFS_DEV_REMOUNT_ALL one) and still be able to get to the
