Third part of new DAX code for 5.8:
- Teach XFS to ask the VFS to drop an inode if the administrator changes
the FS_XFLAG_DAX inode flag such that the S_DAX state would change.
This can result in files changing access modes without requiring an
unmount cycle.

Merge tag 'vfs-5.8-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull DAX updates part three from Darrick Wong:
"Now that the xfs changes have landed, this third piece changes the
FS_XFLAG_DAX ioctl code in xfs to request that the inode be reloaded
after the last program closes the file, if doing so would make a S_DAX
change happen. The goal here is to make dax access mode switching
quicker when possible.
Summary:
- Teach XFS to ask the VFS to drop an inode if the administrator
changes the FS_XFLAG_DAX inode flag such that the S_DAX state would
change. This can result in files changing access modes without
requiring an unmount cycle"

- Keep nfsd clients from unnecessarily breaking their own delegations: Note this requires a small kthreadd addition, discussed at: https://lore.kernel.org/r/1588348912-24781-1-git-send-email-bfields@redhat.com The result is Tejun Heo's suggestion, and he was OK with this going through my tree. - Patch nfsd/clients/ to display filenames, and to fix byte-order when displaying stateid's. - fix a module loading/unloading bug, from Neil Brown. - A big series from Chuck Lever with RPC/RDMA and tracing improvements, and lay some groundwork for RPC-over-TLS.

Pull READ/WRITE_ONCE rework from Will Deacon:
"This the READ_ONCE rework I've been working on for a while, which
bumps the minimum GCC version and improves code-gen on arm64 when

[ Side note: I'm _really_ tempted to raise the minimum gcc version to
4.9, so that we can just say that we require _Generic() support.
That would allow us to more cleanly handle a lot of the cases where we
depend on very complex macros with 'sizeof' or __builtin_choose_expr()
with __builtin_types_compatible_p() etc.
This branch has a workaround for sparse not handling _Generic(),
either, but that was already fixed in the sparse development branch,
so it's really just gcc-4.9 that we'd require. - Linus ]

proc: s_fs_info may be NULL when proc_kill_sb is called
syzbot found that proc_fill_super() fails before filling up sb->s_fs_info,
deactivate_locked_super() will be called and sb->s_fs_info will be NULL.
The proc_kill_sb() does not expect fs_info to be NULL which is wrong.

This time around we have 4 lines of diff in the core framework, removing a
function that isn't used anymore. Otherwise the main new thing for the common
clk framework is that it is selectable in the Kconfig language now. Hopefully
this will let clk drivers and clk consumers be testable on more than the
architectures that support the clk framework. The goal is to introduce some
Kunit tests for the framework.
Outside of the core framework we have the usual set of various driver updates
and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the
largest addition this time around in terms of lines of code. After that the x86
(Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or
upcoming SoCs. After that the dirstat shows the usual suspects working on their
SoC support by fixing minor bugs, correcting data and converting some of their
DT bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix clock support
on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3
drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support aarch32 mode on
aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using composite
clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102 defined
bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx
- Updates and fixup HDMI and video clocks on Meson8b
- Fixup reset polarity on Meson8b
- Fix GPU glitch free mux switch on Meson gx and g12
- A minor fix for the currently unused suspend/resume handling on Renesas RZ/A1 and RZ/A2
- Two more conversions of Renesas DT bindings to json-schema
- Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+

Input: adi - work around module name confict
Making module name conflicts a fatal error breaks sparc64 allmodconfig: Error log: error: the following would cause module name conflict: drivers/char/adi.ko drivers/input/joystick/adi.ko Renaming one of the modules would solve the problem, but then cause other problems because neither of them is automatically loaded and changing the name is likely to break any setup that relies on manually loading it by name. As there is probably no sparc64 system with this kind of ancient joystick attached, work around it by adding a Kconfig dependency that forbids them from both being modules. It is still possible to build the joystick driver if the sparc64 adi driver is built-in.

x86: use proper parentheses around new uaccess macro argument uses
__get_kernel_nofault() didn't have the parentheses around the use of
'src' and 'dst' macro arguments, making the casts potentially do the
wrong thing.
The parentheses aren't necessary with the current very limited use in
mm/access.c, but it's bad form, and future use-cases might have very
unexpected errors as a result.
Do the same for unsafe_copy_loop() while at it, although in that case it
is an entirely internal x86 uaccess helper macro that isn't used
anywhere else and any other use would be invalid anyway.
Fixes:

Tracing updates for 5.8:
No new features this release. Mostly clean ups, restructuring and
documentation.
- Have ftrace_bug() show ftrace errors before the WARN, as the WARN will
reboot the box before the error messages are printed if panic_on_warn
is set.
- Have traceoff_on_warn disable tracing sooner (before prints)
- Write a message to the trace buffer that its being disabled when
disable_trace_on_warning() is set.
- Separate out synthetic events from histogram code to let it be used by
other parts of the kernel.
- More documentation on histogram design.
- Other small fixes and clean ups.

uprobes: ensure that uprobe->offset and ->ref_ctr_offset are properly aligned
uprobe_write_opcode() must not cross page boundary; prepare_uprobe() relies on arch_uprobe_analyze_insn() which should validate "vaddr" but some architectures (csky, s390, and sparc) don't do this. We can remove the BUG_ON() check in prepare_uprobe() and validate the offset early in __uprobe_register(). The new IS_ALIGNED() check matches the alignment check in arch_prepare_kprobe() on supported architectures, so I think that all insns must be aligned to UPROBE_SWBP_INSN_SIZE. Another problem is __update_ref_ctr() which was wrong from the very beginning, it can read/write outside of kmap'ed page unless "vaddr" is aligned to sizeof(short), __uprobe_register() should check this too.
