a8e446e497 dt-bindings: ARM: Clean up PMU compatible list
The "alpha by vendor, reverse-alpha by model" sorting of compatibles
that we seem to have ended up with is decidedly odd. Make it less so.

Also copy the comment from the generic "arm,armv8" CPU binding to help
clarify that the "arm,armv8-pmuv3" binding is rather intended to be a
counterpart to that, for describing implementations without a specific
microarchitecture like the AEMv8 software model.

854bdbae90 dt-bindings: media: csi: Fix clocks description
Commit 1de243b076 ("media: dt-bindings: media: sun4i-csi: Add compatible
for CSI1 on A10/A20") introduced support for the CSI1 controller on A10 and
A20 that unlike CSI0 doesn't have an ISP and therefore only have two
clocks, the bus and module clocks.

The clocks and clock-names properties have thus been modified to allow
either two or tree clocks. However, the current list has the ISP clock at
the second position, which means the bindings expects a list of either
bus and isp, or bus, isp and mod. The initial intent of the patch was
obviously to have bus and mod in the former case.

Let's fix the binding so that it validates properly.

380a129eb2 fs: New zonefs file system
Zonefs is a very simple file system exposing each zone of a zoned block
 device as a file.
 
 Unlike a regular file system with native zoned block device support
 (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
 sequential write constraint of zoned block devices to the user. As a
 result, zonefs is not a POSIX compliant file system. Its goal is to
 simplify the implementation of zoned block devices support in
 applications by replacing raw block device file accesses with a richer
 file based API, avoiding relying on direct block device file ioctls
 which may be more obscure to developers.
 
 One example of this approach is the implementation of LSM
 (log-structured merge) tree structures (such as used in RocksDB and
 LevelDB) on zoned block devices by allowing SSTables to be stored in a
 zone file similarly to a regular file system rather than as a range of
 sectors of a zoned device. The introduction of the higher level
 construct "one file is one zone" can help reducing the amount of changes
 needed in the application while at the same time allowing the use of
 zoned block devices with various programming languages other than C.
 
 Zonefs IO management implementation uses the new iomap generic code.
 Zonefs has been successfully tested using a functional test suite
 (available with zonefs userland format tool on github) and a prototype
 implementation of LevelDB on top of zonefs.

Merge tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs

Pull new zonefs file system from Damien Le Moal:
 "Zonefs is a very simple file system exposing each zone of a zoned
  block device as a file.

  Unlike a regular file system with native zoned block device support
  (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
  sequential write constraint of zoned block devices to the user. As a
  result, zonefs is not a POSIX compliant file system. Its goal is to
  simplify the implementation of zoned block devices support in
  applications by replacing raw block device file accesses with a richer
  file based API, avoiding relying on direct block device file ioctls
  which may be more obscure to developers.

  One example of this approach is the implementation of LSM
  (log-structured merge) tree structures (such as used in RocksDB and
  LevelDB) on zoned block devices by allowing SSTables to be stored in a
  zone file similarly to a regular file system rather than as a range of
  sectors of a zoned device. The introduction of the higher level
  construct "one file is one zone" can help reducing the amount of
  changes needed in the application while at the same time allowing the
  use of zoned block devices with various programming languages other
  than C.

  Zonefs IO management implementation uses the new iomap generic code.
  Zonefs has been successfully tested using a functional test suite
  (available with zonefs userland format tool on github) and a prototype
  implementation of LevelDB on top of zonefs"

Pull vfs file system parameter updates from Al Viro:
 "Saner fs_parser.c guts and data structures. The system-wide registry
  of syntax types (string/enum/int32/oct32/.../etc.) is gone and so is
  the horror switch() in fs_parse() that would have to grow another case
  every time something got added to that system-wide registry.

  New syntax types can be added by filesystems easily now, and their
  namespace is that of functions - not of system-wide enum members. IOW,
  they can be shared or kept private and if some turn out to be widely
  useful, we can make them common library helpers, etc., without having
  to do anything whatsoever to fs_parse() itself.

  And we already get that kind of requests - the thing that finally
  pushed me into doing that was "oh, and let's add one for timeouts -
  things like 15s or 2h". If some filesystem really wants that, let them
  do it. Without somebody having to play gatekeeper for the variants
  blessed by direct support in fs_parse(), TYVM.

  Quite a bit of boilerplate is gone. And IMO the data structures make a
  lot more sense now. -200LoC, while we are at it"

Its behaviour is identical to that of fs_value_is_filename.
It makes no sense, anyway - LOOKUP_EMPTY affects nothing
whatsoever once the pathname has been imported from userland.
And both fs_value_is_filename and fs_value_is_filename_empty
carry an already imported pathname.

    This has been discussed thoroughly at Linux Plumbers.
    Very useful for adding kprobes at bootup.
    Only enabled if "bootconfig" is on the real kernel command line.
 
  - Created dynamic event creation.
    Merges common code between creating synthetic events and
      kprobe events.
 
  - Rename perf "ring_buffer" structure to "perf_buffer"
 
  - Rename ftrace "ring_buffer" structure to "trace_buffer"
    Had to rename existing "trace_buffer" to "array_buffer"
 
  - Allow trace_printk() to work withing (some) tracing code.

7495e0926f bootconfig: Only load bootconfig if "bootconfig" is on the kernel cmdline
As the bootconfig is appended to the initrd it is not as easy to modify as
the kernel command line. If there's some issue with the kernel, and the
developer wants to boot a pristine kernel, it should not be needed to modify
the initrd to remove the bootconfig for a single boot.

As bootconfig is silently added (if the admin does not know where to look
they may not know it's being loaded). It should be explicitly added to the
kernel cmdline. The loading of the bootconfig is only done if "bootconfig"
is on the kernel command line. This will let admins know that the kernel
command line is extended.

Note, after adding printk()s for when the size is too great or the checksum
is wrong, exposed that the current method always looked for the boot config,
and if this size and checksum matched, it would parse it (as if either is
wrong a printk has been added to show this). It's better to only check this
if the boot config is asked to be looked for.

8cff43d46c dt-bindings: clock: Cleanup qcom,videocc bindings for sdm845/sc7180
This makes the qcom,videocc bindings match the recent changes to the
dispcc and gpucc.

1. Switched to using "bi_tcxo" instead of "xo".

2. Adds a description for the XO clock.  Not terribly important but
   nice if it cleanly matches its cousins.

3. Updates the example to use the symbolic name for the RPMH clock and
   also show that the real devices are currently using 2 address cells
   / size cells and fixes the spacing on the closing brace.

4. Split into 2 files.  In this case they could probably share one
   file, but let's be consistent.

e6747e24f1 dt-bindings: clock: Fix qcom,gpucc bindings for sdm845/sc7180/msm8998
The qcom,gpucc bindings had a few problems with them:

1. When things were converted to yaml the name of the "gpll0 main"
   clock got changed from "gpll0" to "gpll0_main".  Change it back for
   msm8998.

2. Apparently there is a push not to use purist aliases for clocks but
   instead to just use the internal Qualcomm names.  For sdm845 and
   sc7180 (where the drivers haven't already been changed) move in
   this direction.

Things were also getting complicated harder to deal with by jamming
several SoCs into one file.  Splitting simplifies things.

48cabc221f dt-bindings: clock: Fix qcom,dispcc bindings for sdm845/sc7180
The qcom,dispcc bindings had a few problems with them:

1. They didn't specify all the clocks that dispcc is a client of.
   Specifically on sc7180 there are two clocks from the DSI PHY and
   two from the DP PHY.  On sdm845 there are actually two DSI PHYs
   (each of which has two clocks) and an extra clock from the gcc.
   These all need to be specified.

2. The sdm845.dtsi has existed for quite some time without specifying
   the clocks.  The Linux driver was relying on global names to match
   things up.  While we should transition things, it should be noted
   in the bindings.

3. The names used the bindings for "xo" and "gpll0" didn't match the
   names that QC used for these clocks internally and this was causing
   confusion / difficulty with their code generation tools.  Switched
   to the internal names to simplify everyone's lives.  It's not quite
   as clean in a purist sense but it should avoid headaches.  This
   officially changes the binding, but that seems OK in this case.

Also note that I updated the example.

f4a6365ae8 There are a few changes to the core framework this time around, in addition to
the normal collection of driver updates to support new SoCs, fix incorrect
 data, and convert various drivers to clk_hw based APIs.
 
 In the core, we allow clk_ops::init() to return an error code now so that we
 can fail clk registration if the callback does something like fail to allocate
 memory. We also add a new "terminate" clk_op so that things done in
 clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now
 when critical clks fail to enable and we support changing clk rates and
 enable/disable state through debugfs when developers compile the kernel
 themselves.
 
 On the driver front, we get support for what seems like a lot of Qualcomm and
 NXP SoCs given that those vendors dominate the diffstat. There are a couple new
 drivers for Xilinx and Amlogic SoCs too. The updates are all small things like
 fixing the way glitch free muxes switch parents, avoiding div-by-zero problems,
 or fixing data like parent names. See the updates section below for more
 details.
 
 Finally, the "basic" clk types have been converted to support specifying
 parents with clk_hw pointers. This work includes an overhaul of the fixed-rate
 clk type to be more modern by using clk_hw APIs.
 
 Core:
  - Let clk_ops::init() return an error code
  - Add a clk_ops::terminate() callback to undo clk_ops::init()
  - Warn about critical clks that fail to enable or prepare
  - Support dangerous debugfs actions on clks with dead code
 
 New Drivers:
  - Support for Xilinx Versal platform clks
  - Display clk controller on qcom sc7180
  - Video clk controller on qcom sc7180
  - Graphics clk controller on qcom sc7180
  - CPU PLLs for qcom msm8916
  - Move qcom msm8974 gfx3d clk to RPM control
  - Display port clk support on qcom sdm845 SoCs
  - Global clk controller on qcom ipq6018
  - Add a driver for BCLK of Freescale SAI cores
  - Add cam, vpe and sgx clock support for TI dra7
  - Add aess clock support for TI omap5
  - Enable clks for CPUfreq on Allwinner A64 SoCs
  - Add Amlogic meson8b DDR clock controller
  - Add input clocks to Amlogic meson8b controllers
  - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
  - i.MX8MP clk driver support
 
 Updates:
  - Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs
  - Detect more PRMCU variants in ux500 driver
  - Adjust the composite clk type to new way of describing clk parents
  - Fixes for clk controllers on qcom msm8998 SoCs
  - Fix gmac main clock for TI dra7
  - Move TI dra7-atl clock header to correct location
  - Fix hidden node name dependency on TI clkctrl clocks
  - Fix Amlogic meson8b mali clock update using the glitch free mux
  - Fix Amlogic pll driver division by zero at init
  - Prepare for split of Renesas R-Car H3 ES1.x and ES2.0+ config symbols
  - Switch more i.MX clk drivers to clk_hw based APIs
  - Disable non-functional divider between pll4_audio_div and
    pll4_post_div on imx6q
  - Fix watchdog2 clock name typo in imx7ulp clock driver
  - Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs
  - Suppress bind attrs for i.MX8M clock driver
  - Add a big comment in imx8qxp-lpcg driver to tell why
    devm_platform_ioremap_resource() shouldn't be used for the driver
  - A correction on i.MX8MN usb1_ctrl parent clock setting

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "There are a few changes to the core framework this time around, in
  addition to the normal collection of driver updates to support new
  SoCs, fix incorrect data, and convert various drivers to clk_hw based
  APIs.

  In the core, we allow clk_ops::init() to return an error code now so
  that we can fail clk registration if the callback does something like
  fail to allocate memory. We also add a new "terminate" clk_op so that
  things done in clk_ops::init() can be undone, e.g. free memory. We
  also spit out a warning now when critical clks fail to enable and we
  support changing clk rates and enable/disable state through debugfs
  when developers compile the kernel themselves.

  On the driver front, we get support for what seems like a lot of
  Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
  There are a couple new drivers for Xilinx and Amlogic SoCs too. The
  updates are all small things like fixing the way glitch free muxes
  switch parents, avoiding div-by-zero problems, or fixing data like
  parent names. See the updates section below for more details.

  Finally, the "basic" clk types have been converted to support
  specifying parents with clk_hw pointers. This work includes an
  overhaul of the fixed-rate clk type to be more modern by using clk_hw
  APIs.

  Core:
   - Let clk_ops::init() return an error code
   - Add a clk_ops::terminate() callback to undo clk_ops::init()
   - Warn about critical clks that fail to enable or prepare
   - Support dangerous debugfs actions on clks with dead code

  New Drivers:
   - Support for Xilinx Versal platform clks
   - Display clk controller on qcom sc7180
   - Video clk controller on qcom sc7180
   - Graphics clk controller on qcom sc7180
   - CPU PLLs for qcom msm8916
   - Move qcom msm8974 gfx3d clk to RPM control
   - Display port clk support on qcom sdm845 SoCs

   - Add Amlogic meson8b DDR clock controller
   - Add input clocks to Amlogic meson8b controllers
   - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
   - i.MX8MP clk driver support

  Updates:

2a8aa18c11 dt-bindings: clk: qcom: Fix self-validation, split, and clean cruft
The 'qcom,gcc.yaml' file failed self-validation (dt_binding_check)
because it required a property to be either (3 entries big),
(3 entries big), or (7 entries big), but not more than one of those
things.  That didn't make a ton of sense.

This patch splits all of the exceptional device trees (AKA those that
would have needed if/then/else rules) from qcom,gcc.yaml.  It also
cleans up some cruft found while doing that.

After this lands, this worked for me atop clk-next with just the known
error about msm8998:
  for f in \
    Documentation/devicetree/bindings/clock/qcom,gcc-apq8064.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-ipq8074.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-msm8996.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-msm8998.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-qcs404.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-sc7180.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-sm8150.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc.yaml; do \
      ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \
  done

I then picked this patch atop linux-next (next-20200129) and ran:
  # Delete broken yaml:
  rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml
  ARCH=arm64 make dt_binding_check | grep 'clock/qcom'
...and that didn't seem to indicate problems.

Arbitrary decisions made (yell if you want changed):
- Left all the older devices (where clocks / clock-names weren't
  specified) in a single file.
- Didn't make clocks "required" for msm8996 but left them as listed.
  This seems a little weird but it matches the old binding.

Misc cleanups as part of this patch:
- Fixed schema id to not have "bindings/" as per Rob [1].
- Listed include files as per Stephen.
- sm8150 was claimed to be same set of clocks as sc7180, but driver
  and dts appear to say that "bi_tcxo_ao" doesn't exist.  Fixed.
- In "apq8064", "#thermal-sensor-cells" was missing the "#".
- Got rid of "|" at the end of top description since spacing doesn't
  matter.
- Changed indentation to consistently 2 spaces (it was 3 in some
  places).
- Added period at the end of protected-clocks description.
- No space before ":".
- Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include.
- Updated sc7180/sm8150 example to use larger address/size cells as
  per reality.
- Updated sc7180/sm8150 example to point to the sleep_clk rather than
  <0>.
- Made it so that gcc-ipq8074 didn't require #power-domain-cells since
  actual dts didn't have it and I got no hits from:
    git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h
- Made it so that gcc-qcs404 didn't require #power-domain-cells since
  actual dts didn't have it and I got no hits from:
    git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h

Noticed, but not done in this patch (volunteers needed):
- Add "aud_ref_clk" to sm8150 bindings / dts even though I found a
  reference to it in "gcc-sm8150.c".
- Fix node name in actual ipq8074 to be "clock-controller" (it's gcc).
- Since the example doesn't need phandes to exist, in msm8998 could
  just make up places providing some of the clocks currently bogused
  out with <0>.
- On msm8998 clocks are listed as required but current dts doesn't
  have them.

5f2fb52fac kbuild: rename hostprogs-y/always to hostprogs/always-y
In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.

It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.

This commit renames like follows:

  always       ->  always-y
  hostprogs-y  ->  hostprogs

So, scripts/Makefile will look like this:

  always-$(CONFIG_BUILD_BIN2C) += ...
  always-$(CONFIG_KALLSYMS)    += ...
      ...
  hostprogs := $(always-y) $(always-m)

I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.

The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

faa7bdd7e9 kbuild: fix the document to use extra-y for vmlinux.lds
The difference between "always" and "extra-y" is that the targets
listed in $(always) are always built, whereas the ones in $(extra-y)
are built only when KBUILD_BUILTIN is set.

So, "make modules" does not build the targets in $(extra-y).

vmlinux.lds is only needed for linking vmlinux. So, adding it to extra-y
is more correct. In fact, arch/x86/kernel/Makefile does this.

Fix the example code.

4dcb78ee57 intel_idle: Introduce 'states_off' module parameter
In certain system configurations it may not be desirable to use some
C-states assumed to be available by intel_idle and the driver needs
to be prevented from using them even before the cpuidle sysfs
interface becomes accessible to user space.  Currently, the only way
to achieve that is by setting the 'max_cstate' module parameter to a
value lower than the index of the shallowest of the C-states in
question, but that may be overly intrusive, because it effectively
makes all of the idle states deeper than the 'max_cstate' one go
away (and the C-state to avoid may be in the middle of the range
normally regarded as available).

To allow that limitation to be overcome, introduce a new module
parameter called 'states_off' to represent a list of idle states to
be disabled by default in the form of a bitmask and update the
documentation to cover it.

to cover it.
