2c81593889 Rust fixes for v6.9
- Soundness: make internal functions generated by the 'module!' macro
    inaccessible, do not implement 'Zeroable' for 'Infallible' and
    require 'Send' for the 'Module' trait.
 
  - Build: avoid errors with "empty" files and workaround 'rustdoc' ICE.
 
  - Kconfig: depend on '!CFI_CLANG' and avoid selecting 'CONSTRUCTORS'.
 
  - Code docs: remove non-existing key from 'module!' macro example.
 
  - Docs: trivial rendering fix in arch table.

57865f3970 RISC-V Fixes for 6.9-rc6
* A fix for TASK_SIZE on rv64/NOMMU, to reflect the lack of user/kernel
   separation.
 * A fix to avoid loading rv64/NOMMU kernel past the start of RAM.
 * A fix for RISCV_HWPROBE_EXT_ZVFHMIN on ilp32 to avoid signed integer
   overflow in the bitmask.
 * The sud_test kselftest has been fixed to properly swizzle the syscall
   number into the return register, which are not the same on RISC-V.
 * A fix for a build warning in the perf tools on rv32.
 * A fix for the CBO selftests, to avoid non-constants leaking into the
   inline asm.
 * A pair of fixes for T-Head PBMT errata probing, which has been renamed
   MAE by the vendor.

f357439229 clk: qcom: clk-cbf-8996: use HUAYRA_APSS register map for cbf_pll
The register map used for 'cbf_pll' is the same as the one defined for
the CLK_ALPHA_PLL_TYPE_HUAYRA_APSS indice in the 'clk_alpha_pll_regs'
array.

Drop the local register map and use the global one instead to reduce
code duplication.

No functional changes intended. Compile tested only.

5fce38e2a1 clk: qcom: apss-ipq-pll: use stromer ops for IPQ5018 to fix boot failure
Booting v6.8 results in a hang on various IPQ5018 based boards.
Investigating the problem showed that the hang happens when the
clk_alpha_pll_stromer_plus_set_rate() function tries to write
into the PLL_MODE register of the APSS PLL.

Checking the downstream code revealed that it uses [1] stromer
specific operations for IPQ5018, whereas in the current code
the stromer plus specific operations are used.

The ops in the 'ipq_pll_stromer_plus' clock definition can't be
changed since that is needed for IPQ5332, so add a new alpha pll
clock declaration which uses the correct stromer ops and use this
new clock for IPQ5018 to avoid the boot failure.

Also, change pll_type in 'ipq5018_pll_data' to
CLK_ALPHA_PLL_TYPE_STROMER to better reflect that it is a Stromer
PLL and change the apss_ipq_pll_probe() function accordingly.

e88f03230d clk: qcom: gcc-ipq8074: rework nss_port5/6 clock to multiple conf
Rework nss_port5/6 to use the new multiple configuration implementation
and correctly fix the clocks for these port under some corner case.

This is particularly relevant for device that have 2.5G or 10G port
connected to port5 or port 6 on ipq8074. As the parent are shared
across multiple port it may be required to select the correct
configuration to accomplish the desired clock. Without this patch such
port doesn't work in some specific ethernet speed as the clock will be
set to the wrong frequency as we just select the first configuration for
the related frequency instead of selecting the best one.

89da22456a clk: qcom: clk-rcg2: add support for rcg2 freq multi ops
Some RCG frequency can be reached by multiple configuration.

Add clk_rcg2_fm_ops ops to support these special RCG configurations.

These alternative ops will select the frequency using a CEIL policy.

When the correct frequency is found, the correct config is selected by
calculating the final rate (by checking the defined parent and values
in the config that is being checked) and deciding based on the one that
is less different than the requested one.

These check are skipped if there is just one config for the requested
freq.

qcom_find_freq_multi is added to search the freq with the new struct
freq_multi_tbl.
__clk_rcg2_select_conf is used to select the correct conf by simulating
the final clock.
If a conf can't be found due to parent not reachable, a WARN is printed
and -EINVAL is returned.

d06b104364 clk: qcom: clk-rcg: introduce support for multiple conf for same freq
Some RCG frequency can be reached by multiple configuration.

We currently declare multiple configuration for the same frequency but
that is not supported and always the first configuration will be taken.

These multiple configuration are needed as based on the current parent
configuration, it may be needed to use a different configuration to
reach the same frequency.

To handle this introduce 3 new macro, C, FM and FMS:

- C is used to declare a freq_conf where src, pre_div, m and n are
  provided.

- FM is used to declare a freq_multi_tbl with the frequency and an
  array of confs to insert all the config for the provided frequency.

- FMS is used to declare a freq_multi_tbl with the frequency and an
  array of a single conf with the provided src, pre_div, m and n.

Struct clk_rcg2 is changed to add a union type to reference a simple
freq_tbl or a complex freq_multi_tbl.

8c618b58c8 perf test: Reintroduce -p/--parallel and make -S/--sequential the default
We can't default to doing parallel tests as there are tests that compete
for the same resources and thus clash, for instance tests that put in
place 'perf probe' probes, that clean the probes without regard to other
tests needs, ARM64 coresight tests, Intel PT ones, etc.

So reintroduce --p/--parallel and make -S/--sequential the default.

We need to come up with infrastructure that state which tests can't run
in parallel because they need exclusive access to some resource,
something as simple as "probes" that would then avoid 'perf probe' tests
from running while other such test is running, or make the tests more
resilient, till then we can't use parallel mode as default.

While at it, document all these options in the 'perf test' man page.

   3c7a8e190b ("uapi: introduce uapi-friendly macros for GENMASK")

That just causes perf to rebuild. Its just some macros going to an uapi
header that we now have to grab a copy into tools/ as well.

This addresses this perf build warning:

8f21164321 tools headers x86 cpufeatures: Sync with the kernel sources to pick BHI mitigation changes
To pick the changes from:

  ec9404e40e ("x86/bhi: Add BHI mitigation knob")
  be482ff950 ("x86/bhi: Enumerate Branch History Injection (BHI) bug")
  0f4a837615 ("x86/bhi: Define SPEC_CTRL_BHI_DIS_S")
  7390db8aea ("x86/bhi: Add support for clearing branch history at syscall entry")

This causes these perf files to be rebuilt and brings some X86_FEATURE

tools/arch/x86/lib/mem{cpy,set}_64.S with the kernel sources:

      CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o

2b87383c88 perf annotate: Fix data type profiling on stdio
The loop in hists__find_annotations() never set the 'nd' pointer to NULL
and it makes stdio output repeating the last element forever.  I think
it doesn't set to NULL for TUI to prevent it from exiting unexpectedly.
But it should just set on stdio mode.

8524d71ceb perf build: Pretend scandirat is missing with msan
Memory sanitizer lacks an interceptor for scandirat, reporting all
memory it allocates as uninitialized. Memory sanitizer has a scandir
interceptor so use the fallback function in this case. This allows
'perf test' to run under memory sanitizer.

Additional notes from Ian on running in this mode:

Note, as msan needs to instrument memory allocations libraries need to
be compiled with it. I lacked the msan built libraries and so built
with:
```
$ make -C tools/perf O=/tmp/perf DEBUG=1 EXTRA_CFLAGS="-O0 -g
-fno-omit-frame-pointer -fsanitize=memory
-fsanitize-memory-track-origins" CC=clang CXX=clang++ HOSTCC=clang
NO_LIBTRACEEVENT=1 NO_LIBELF=1 BUILD_BPF_SKEL=0 NO_LIBPFM=1
```
oh, I disabled libbpf here as the bpf system call also lacks msan interceptors.

8f3ec810bb perf annotate: Update DSO binary type when trying build-id
dso__disassemble_filename() tries to get the filename for objdump (or
capstone) using build-id.  But I found sometimes it didn't disassemble
some functions.

It turned out that those functions belong to a DSO which has no binary
type set.  It seems it sets the binary type for some special files only
- like kernel (kallsyms or kcore) or BPF images.  And there's a logic to
skip dso with DSO_BINARY_TYPE__NOT_FOUND.

As it's checked the build-id cache link, it should set the binary type
as DSO_BINARY_TYPE__BUILD_ID_CACHE.

f35847de2a perf annotate: Fallback disassemble to objdump when capstone fails
I found some cases that capstone failed to disassemble.  Probably my
capstone is an old version but anyway there's a chance it can fail.  And
then it silently stopped in the middle.  In my case, it didn't
understand "RDPKRU" instruction.

Let's check if the capstone disassemble reached the end of the function
and fallback to objdump if not.
