7e5385dc72 clk: rockchip: drop old_rate calculation on pll rate changes
Previously when everything happened in the set_rate callbacks itself we
needed the old_rate value for the possible rate rollback, so that made
it easy to also use it in the debug output.

Now with the param-handling being done in separate functions, reading and
recalculating the current pll rate only to use it in a debug message that
won't get displayed in regular cases anyway is quite a waste.

Therefore drop that value from the debug output. In the worst case that
previous rate will have been displayed on the rate change before.

c9c3c6eecc clk: rockchip: simplify GRF handling in pll clocks
With the previous commit, the clock drivers now know at init time if the
GRF regmap is available. That means if it isn't available then, it also
won't become available later and we can therefore switch PLLs, that need
the GRF for the lock-status, to read-only mode - similar behaviour as the
aborting of rate changes we did before.

This saves some conditionals on every rate change and we can also drop
the rockchip_clk_get_grf function completely.

6f339dc271 clk: rockchip: lookup General Register Files in rockchip_clk_init
In the distant past syscons were initialized pretty late and weren't
available at the time the clock init ran. As the GRF is mainly needed
for PLL lock-status checking, we had this lazy init that tried to grab
the syscon on PLL rate changes and denied these changes if it was not
available.

These days syscons are available very early and recent addition to
rockchip clocks, like the PLL clk_init actually also rely on them
being available at that time, so there is no need to keep that lazy
init around, as it will also result in some more simplifications in
other parts of the clock-code.

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"

02fc59a0d2 f2fs/crypto: fix xts_tweak initialization
Commit 0b81d07790 ("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 0b81d07790

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.

4f1b50c3e3 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.

Fixes: a1b3695820

45996492e5 orangefs: fix orangefs_superblock locking
* 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
rest of the list.

15dbc136df Power management and ACPI material for v4.6-rc1, part 2
- Fix for an intel_pstate driver issue related to the handling of
    MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki).
 
  - cpufreq core cleanups related to starting governors and frequency
    synchronization during resume from system suspend and a locking
    fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
 
  - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
    Michael Neuling, Richard Cochran, Shilpasri Bhat).
 
  - intel_idle driver update preventing some Skylake-H systems
    from hanging during initialization by disabling deep C-states
    mishandled by the platform in the problematic configurations (Len
    Brown).
 
  - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman
    Chandramouli).
 
  - cpuidle menu governor updates to make it always honor PM QoS
    latency constraints (and prevent C1 from being used as the
    fallback C-state on x86 when they are set below its exit latency)
    and to restore the previous behavior to fall back to C1 if the next
    timer event is set far enough in the future that was changed in 4.4
    which led to an energy consumption regression (Rik van Riel, Rafael
    Wysocki).
 
  - New device ID for a future AMD UART controller in the ACPI driver
    for AMD SoCs (Wang Hongcheng).
 
  - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
    scaling (AVS) driver (David Wu).
 
  - ACPI PCI resources management fix for the handling of IO space
    resources on architectures where the IO space is memory mapped
    (IA64 and ARM64) broken by the introduction of common ACPI
    resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
 
  - Fix for the ACPI backend of the generic device properties API
    to make it parse non-device (data node only) children of an
    ACPI device correctly (Irina Tirdea).
 
  - Fixes for the handling of global suspend flags (introduced in 4.4)
    during hibernation and resume from it (Lukas Wunner).
 
  - Support for obtaining configuration information from Device Trees
    in the PM clocks framework (Jon Hunter).
 
  - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
    King, Geert Uytterhoeven).
