3e39e68dfb cpufreq/amd-pstate-ut: Add test case for mode switches
There is a state machine in the amd-pstate driver utilized for
switches for all modes. To make sure that cleanup and setup works
properly for each mode add a unit test case that tries all
combinations.

ad4caad58d cpufreq: amd-pstate: Merge amd_pstate_highest_perf_set() into amd_get_boost_ratio_numerator()
The special case in amd_pstate_highest_perf_set() is the value used
for calculating the boost numerator.  Merge this into
amd_get_boost_ratio_numerator() and then use that to calculate boost
ratio.

This allows dropping more special casing of the highest perf value.

279f838a61 x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator()
AMD systems that support preferred cores will use "166" as their
numerator for max frequency calculations instead of "255".

Add a function for detecting preferred cores by looking at the
highest perf value on all cores.

If preferred cores are enabled return 166 and if disabled the
value in the highest perf register. As the function will be called
multiple times, cache the values for the boost numerator and if
preferred cores will be enabled in global variables.

Commit b4bc9f9e27 ("cpufreq: ti-cpufreq: add support for omap34xx
and omap36xx") introduced special handling for OMAP3 class devices
where syscon node may not be present. However, this also creates a bug
where the syscon node is present, however the offset used to read
is beyond the syscon defined range.

Fix this by providing a quirk option that is populated when such
special handling is required. This allows proper failure for all other
platforms when the syscon node and efuse offsets are mismatched.

017fa3e891 minmax: simplify and clarify min_t()/max_t() implementation
This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.

That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

4477b39c32 minmax: add a few more MIN_T/MAX_T users
Commit 3a7e02c040 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.

The complexity of those macros stems from two issues:

 (a) trying to use them in situations that require a C constant
     expression (in static initializers and for array sizes)

 (b) the type sanity checking

and MIN_T/MAX_T avoids both of these issues.

Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.

But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.

However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.

This does exactly that.

Which in turn will then allow for much simpler implementations of
min_t()/max_t().  All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.

We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:

  $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
  clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]

This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.

'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.

All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

Merge tag 'cxl-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL updates from Dave Jiang:
 "Core:

   - A CXL maturity map has been added to the documentation to detail
     the current state of CXL enabling.

     It provides the status of the current state of various CXL features
     to inform current and future contributors of where things are and
     which areas need contribution.

   - A notifier handler has been added in order for a newly created CXL
     memory region to trigger the abstract distance metrics calculation.

     This should bring parity for CXL memory to the same level vs
     hotplugged DRAM for NUMA abstract distance calculation. The
     abstract distance reflects relative performance used for memory
     tiering handling.

   - An addition for XOR math has been added to address the CXL DPA to
     SPA translation.

     CXL address translation did not support address interleave math
     with XOR prior to this change.

  Fixes:

   - Fix to address race condition in the CXL memory hotplug notifier

   - Add missing MODULE_DESCRIPTION() for CXL modules

   - Fix incorrect vendor debug UUID define

  Misc:

   - A warning has been added to inform users of an unsupported

   - The ENXIO error code has been replaced with EBUSY for inject poison

Pull vfs fixes from Christian Brauner:
 "This contains two fixes for this merge window:

  VFS:

   - I noticed that it is possible for a privileged user to mount most
     filesystems with a non-initial user namespace in sb->s_user_ns.

     When fsopen() is called in a non-init namespace the caller's
     namespace is recorded in fs_context->user_ns. If the returned file
     descriptor is then passed to a process privileged in init_user_ns,
     that process can call fsconfig(fd_fs, FSCONFIG_CMD_CREATE*),
     creating a new superblock with sb->s_user_ns set to the namespace
     of the process which called fsopen().

     This is problematic as only filesystems that raise FS_USERNS_MOUNT
     are known to be able to support a non-initial s_user_ns. Others may
     suffer security issues, on-disk corruption or outright crash the
     kernel. Prevent that by restricting such delegation to filesystems
     that allow FS_USERNS_MOUNT.

     Note, that this delegation requires a privileged process to
     actually create the superblock so either the privileged process is
     cooperaing or someone must have tricked a privileged process into
     operating on a fscontext file descriptor whose origin it doesn't
     know (a stupid idea).

     The bug dates back to about 5 years afaict.

  Misc:

   - Fix hostfs parsing when the mount request comes in via the legacy
     mount api.

     In the legacy mount api hostfs allows to specify the host directory
     mount without any key.

     Restore that behavior"

910bfc26d1 Rust changes for v6.11
The highlight is the establishment of a minimum version for the Rust
 toolchain, including 'rustc' (and bundled tools) and 'bindgen'.
 
 The initial minimum will be the pinned version we currently have, i.e.
 we are just widening the allowed versions. That covers 3 stable Rust
 releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta,
 plus nightly.
 
 This should already be enough for kernel developers in distributions
 that provide recent Rust compiler versions routinely, such as Arch
 Linux, Debian Unstable (outside the freeze period), Fedora Linux,
 Gentoo Linux (especially the testing channel), Nix (unstable) and
 openSUSE Slowroll and Tumbleweed.
 
 In addition, the kernel is now being built-tested by Rust's pre-merge
 CI. That is, every change that is attempting to land into the Rust
 compiler is tested against the kernel, and it is merged only if it
 passes. Similarly, the bindgen tool has agreed to build the kernel in
 their CI too.
 
 Thus, with the pre-merge CI in place, both projects hope to avoid
 unintentional changes to Rust that break the kernel. This means that,
 in general, apart from intentional changes on their side (that we
 will need to workaround conditionally on our side), the upcoming Rust
 compiler versions should generally work.
 
 In addition, the Rust project has proposed getting the kernel into
 stable Rust (at least solving the main blockers) as one of its three
 flagship goals for 2024H2 [1].
 
 I would like to thank Niko, Sid, Emilio et al. for their help promoting
 the collaboration between Rust and the kernel.
 
 [1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals
 
 Toolchain and infrastructure:
 
  - Support several Rust toolchain versions.
 
  - Support several bindgen versions.
 
  - Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc'
    having been dropped last cycle.
 
  - Provide proper error reporting for the 'rust-analyzer' target.
 
 'kernel' crate:
 
  - Add 'uaccess' module with a safe userspace pointers abstraction.
 
  - Add 'page' module with a 'struct page' abstraction.
 
  - Support more complex generics in workqueue's 'impl_has_work!' macro.
 
 'macros' crate:
 
  - Add 'firmware' field support to the 'module!' macro.
 
  - Improve 'module!' macro documentation.

Merge tag 'rust-6.11' of https://github.com/Rust-for-Linux/linux

Pull Rust updates from Miguel Ojeda:
 "The highlight is the establishment of a minimum version for the Rust
  toolchain, including 'rustc' (and bundled tools) and 'bindgen'.

  The initial minimum will be the pinned version we currently have, i.e.
  we are just widening the allowed versions. That covers three stable
  Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow),
  plus beta, plus nightly.

  This should already be enough for kernel developers in distributions
  that provide recent Rust compiler versions routinely, such as Arch
  Linux, Debian Unstable (outside the freeze period), Fedora Linux,
  Gentoo Linux (especially the testing channel), Nix (unstable) and
  openSUSE Slowroll and Tumbleweed.

  In addition, the kernel is now being built-tested by Rust's pre-merge
  CI. That is, every change that is attempting to land into the Rust
  compiler is tested against the kernel, and it is merged only if it
  passes. Similarly, the bindgen tool has agreed to build the kernel in
  their CI too.

  Thus, with the pre-merge CI in place, both projects hope to avoid
  unintentional changes to Rust that break the kernel. This means that,
  in general, apart from intentional changes on their side (that we will
  need to workaround conditionally on our side), the upcoming Rust
  compiler versions should generally work.

  In addition, the Rust project has proposed getting the kernel into
  stable Rust (at least solving the main blockers) as one of its three
  flagship goals for 2024H2 [1].

  I would like to thank Niko, Sid, Emilio et al. for their help
  promoting the collaboration between Rust and the kernel.

  Toolchain and infrastructure:

   - Support several Rust toolchain versions.

   - Support several bindgen versions.

   - Remove 'cargo' requirement and simplify 'rusttest', thanks to
     'alloc' having been dropped last cycle.

   - Provide proper error reporting for the 'rust-analyzer' target.

  'kernel' crate:

   - Add 'uaccess' module with a safe userspace pointers abstraction.

   - Add 'page' module with a 'struct page' abstraction.

   - Support more complex generics in workqueue's 'impl_has_work!'
     macro.

  'macros' crate:

   - Add 'firmware' field support to the 'module!' macro.

   - Improve 'module!' macro documentation.

  Documentation:

   - Provide instructions on what packages should be installed to build
     the kernel in some popular Linux distributions.

   - Introduce the new kernel.org LLVM+Rust toolchains.

   - Explain '#[no_std]'.

0421621158 firewire fixes for 6.11-rc1
Two commits are included to fix some regressions. These commits should also
 be applied to the v6.10 kernel as well.
 
 The recent integration of compiler collections introduced the technology
 to check flexible array length at runtime by providing proper annotations.
 In v6.10 kernel, a patch was merged into firewire subsystem to utilize it,
 however the annotation was inadequate. There is also the related change for
 the flexible array in sound subsystem, but it causes a regression where
 the data in the payload of isochronous packet is incorrect for some
 devices. These bugs are now fixed.
