583ad88871 drm/amd/display: Fix possible infinite loop in DP LT fallback
[Why]
It's possible for some fallback scenarios to result in infinite looping
during link training.

[How]
This change modifies DP LT fallback behavior to more closely match the
DP standard. Keep track of the link rate during the EQ_FAIL fallback,
and use it as the maximum link rate for the CR sequence.

92909cde32 drm/amd/display: Wait DMCUB to idle state before reset.
[WHY]
Very low rate to cause memory access issue while resetting
DMCUB after the halt command was sent to it.
The process of stopping fw of DMCUB may be timeout, that means
it is not in idle state, such as the window frames may still be
kept in cache, so reset by force will cause MMHUB hang.

[HOW]
After the halt command was sent, keep checking the DMCUB state until
it is idle.

8440f57532 drm/amd/display: Pass the new context into disable OTG WA
[Why]
When enabling an HPO stream for the first time after having previously
enabled a DIO stream there may be lingering DIO FIFO errors even though
the DIO is no longer enabled.

These can cause display clock change to hang if we don't apply the
OTG disable workaround since the ramping logic is tied to OTG on.

[How]
The workaround wasn't being applied in the sequence of:

1 DIO stream
0 streams
1 HPO stream

because current_state has no stream or planes in its context - and
it's only swapped after optimize has finished.

We should be using the incoming context instead to determine whether
this logic is needed or not.

e2c6170a55 dt-bindings: PCI: xilinx-cpm: Fix reg property order
All existing vendor DTSes are using "cpm_slcr" reg followed by "cfg" reg.

This order is also suggested by node name which is pcie@fca10000 which
suggests that cpm_slcr register should be the first.

Driver itself is using devm_platform_ioremap_resource_byname() for both
names that's why there is no functional change even on description which
are using current order.

But still prefer to change order to cover currently used description.

17eabd4256 afs: Fix infinite loop found by xfstest generic/676
In AFS, a directory is handled as a file that the client downloads and
parses locally for the purposes of performing lookup and getdents
operations.  The in-kernel afs filesystem has a number of functions that
do this.

A directory file is arranged as a series of 2K blocks divided into
32-byte slots, where a directory entry occupies one or more slots, plus
each block starts with one or more metadata blocks.

When parsing a block, if the last slots are occupied by a dirent that
occupies more than a single slot and the file position points at a slot
that's not the initial one, the logic in afs_dir_iterate_block() that
skips over it won't advance the file pointer to the end of it.  This
will cause an infinite loop in getdents() as it will keep retrying that
block and failing to advance beyond the final entry.

Fix this by advancing the file pointer if the next entry will be beyond
it when we skip a block.

This was found by the generic/676 xfstest but can also be triggered with
something like:

	~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

ff979b2a9d ftrace/fgraph: fix increased missing-prototypes warnings
After commit e999995c84 ("ftrace: cleanup ftrace_graph_caller enable
and disable") merged into the linux-next tree, the kernel test robot
(lkp@intel.com) has send out report that there are increased missing-prototypes
warnings caused by that commit.

COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-11.3.0 make.cross W=1 \
	O=build_dir ARCH=sh SHELL=/bin/bash kernel/trace/
warning: no previous prototype for 'ftrace_enable_ftrace_graph_caller' [-Wmissing-prototypes]

warning: no previous prototype for 'ftrace_return_to_handler' [-Wmissing-prototypes]
warning: no previous prototype for 'ftrace_graph_sleep_time_control' [-Wmissing-prototypes]

BTW there are so many missing-prototypes warnings if build kernel with "W=1".

The increased warnings for 'ftrace_[enable,disable]_ftrace_graph_caller'
is caused by CONFIG_FUNCTION_GRAPH_TRACER && !CONFIG_DYNAMIC_FTRACE,
so the declarations in <linux/ftrace.h> can't be seen in fgraph.c.

And this warning can't reproduce on x86_64 since x86_64 select
HAVE_FUNCTION_GRAPH_TRACER only when DYNAMIC_FTRACE, so fgraph.c will
always see the declarations in <linux/ftrace.h>.

This patch fix the increased warnings by put the definitions in
CONFIG_DYNAMIC_FTRACE although there are no real problems exist.

In the Rust for Linux patch series, Jonathan Corbet requested [1] that
we avoid binary assets (such as the logo), possibly by recreating
them in SVG format.

However, it turns out there is no SVG version of the Linux logo
in the kernel tree yet, only a GIF one from the pre-v2.0.0 days.

This patch fixes that by adding a SVG version of the Linux logo,
which we could then use in the Rust for Linux documentation and
other similar places.

This is a vector re-illustration by Garrett LeSage of the original
logo by Larry Ewing, plus cleanups by IFo Hancroft.

The file was imported as-is from:

    ecd40de642/tux.svg

The stated license in the repository is:

> Public domain http://creativecommons.org/publicdomain/zero/1.0/
>
> ...but, if anyone asks:
>
> Tux was originally made by Larry Ewing in the Gimp, re-illustrated
> in vector by Garrett LeSage, using Inkscape and refined and
> cleaned up by IFo Hancroft.

Here, the acknowledgement requirement has been made mandatory to
match the wording of the existing GIF logo in `COPYING-logo`.

Both Garrett LeSage and IFo Hancroft gave their permission [2,3]
to use their re-illustration with the license as given in
the `COPYING-logo` file.

fae35da4ac docs: move Linux logo into a new images folder
Having assets in the top-level `Documentation` directory can make
it harder to find the documents one needs, especially if we want
to add more of them later on.

Instead, create a new `images` folder inside it that is used
to hold assets such as logos.

In addition, update the reference in `scripts/spdxcheck-test.sh`.

       The default value of language becomes to 'en' now.

[1]: https://www.sphinx-doc.org/en/master/changes.html#release-5-0-0-released-may-30-2022

It results in a new warning from Sphinx 5.0.0 [sic]:

    Update your configuration to a valid langauge code. Falling
    back to 'en' (English).

c6031b1dbb kbuild: make *.mod rule robust against too long argument error
Like built-in.a, the command length of the *.mod rule scales with
the depth of the directory times the number of objects in the Makefile.

Add $(obj)/ by the shell command (awk) instead of by Make's builtin
function.

In-tree modules still have some room to the limit (ARG_MAX=2097152),
but this is more future-proof for big modules in a deep directory.

For example, you can build i915 as a module (CONFIG_DRM_I915=m) and
compare drivers/gpu/drm/i915/.i915.mod.cmd with/without this commit.

The issue is more critical for external modules because the M= path
can be very long as Jeff Johnson reported before [1].

cd968b97c4 kbuild: make built-in.a rule robust against too long argument error
Kbuild runs at the top of objtree instead of changing the working
directory to subdirectories. I think this design is nice overall but
some commands have a scalability issue.

The build command of built-in.a is one of them whose length scales with:

    O(D * N)

Here, D is the length of the directory path (i.e. $(obj)/ prefix),
N is the number of objects in the Makefile, O() is the big O notation.

The deeper directory the Makefile directory is located, the more easily
it will hit the too long argument error.

We can make it better. Trim the $(obj)/ by Make's builtin function, and
restore it by a shell command (sed).

With this, the command length scales with:

    O(D + N)

In-tree modules still have some room to the limit (ARG_MAX=2097152),
but this is more future-proof for big modules in a deep directory.

For example, you can build i915 as builtin (CONFIG_DRM_I915=y) and
compare drivers/gpu/drm/i915/.built-in.a.cmd with/without this commit.

31cb50b559 kbuild: check static EXPORT_SYMBOL* by script instead of modpost
The 'static' specifier and EXPORT_SYMBOL() are an odd combination.

Commit 15bfc2348d ("modpost: check for static EXPORT_SYMBOL*
functions") tried to detect it, but this check has false negatives.

Here is the sample code.

  Makefile:

    obj-y += foo1.o foo2.o

  foo1.c:

    #include <linux/export.h>
    static void foo(void) {}
    EXPORT_SYMBOL(foo);

  foo2.c:

    void foo(void) {}

foo1.c exports the static symbol 'foo', but modpost cannot catch it
because it is fooled by foo2.c, which has a global symbol with the
same name.

s->is_static is cleared if a global symbol with the same name is found
somewhere, but EXPORT_SYMBOL() and the global symbol do not necessarily
belong to the same compilation unit.

This check should be done per compilation unit, but I do not know how
to do it in modpost. modpost runs against vmlinux.o or modules, which
merges multiple objects, then forgets their origin.

modpost cannot parse individual objects because they may not be ELF but
LLVM IR when CONFIG_LTO_CLANG=y.

Add a simple bash script to parse the output from ${NM}. This works for
CONFIG_LTO_CLANG=y because llvm-nm can dump symbols of LLVM IR files.

Revert 15bfc2348d.

5a18db2e92 drm/i915: Treat DMRRS as static DRRS
Some machines declare DRRS type = seamless, DRRS = no, DMRRS = yes.
I *think* DMRRS stands for "dynamcic media refresh rate", and
I suspect the way it's meant to work is that it lets the driver
switch refresh rates to match the frame rate for media playback.
Obviously for us all that kind of policy stuff is entirely up to
userspace, so the only thing we may do is make the extra refresh
rate(s) available.

So let's treat this case as just static DRRS for now. In the
future We might want to differentiate the "seamless w/ downclocking"
vs. "seamless w/o downclocking" cases so that we could do seamless
refresh rate changes for systems that only claim to support DMRRS.

6e939738da drm/i915: Accept more fixed modes with VRR panels
It seem that when dealing with VRR capable eDP panels we need
to accept fixed modes with variable vblank length (which is what
VRR varies dynamically). Typically the preferred mode seems to be
a non-VRR more (lowish dotclock/refresh rate + short vblank).

We also have examples where it looks like even the hblank length
is a bit different between the preferred mode vs. VRR mode(s).
So let's just accept anything that has matching hdisp+vdisp+flags.

a051246b78 mmc: block: Fix CQE recovery reset success
The intention of the use of mmc_blk_reset_success() in
mmc_blk_cqe_recovery() was to prevent repeated resets when retrying and
getting the same error. However, that may not be the case - any amount
of time and I/O may pass before another recovery is needed, in which
case there would be no reason to deny it the opportunity to recover via
a reset if necessary. CQE recovery is expected seldom and failure to
recover (if the clear tasks command fails), even more seldom, so it is
better to allow the reset always, which can be done by calling
mmc_blk_reset_success() always.

So let's move this option into the existing Kconfig submenu that already
depends on CONFIG_EFI, and while at it, give some other options the same
treatment.

Also clean up a small wart where the efi/ subdirectory is listed twice.
Let's just list it unconditionally so that both EFI and UEFI_CPER based
pieces will be built independently (the latter only depends on the
former on !X86)
