Pull modules updates from Luis Chamberlain:
 "Summary of the changes worth highlighting from most interesting to
  boring below:

   - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
     circumvent the protection he put in place in year 2020 to prevent
     proprietary modules from using GPL only symbols, and also ensuring
     proprietary modules which export symbols grandfather their taint.

     That was done through year 2020 commit 262e6ae7 ("modules:
     inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
     clarifing __symbol_get() was only ever intended to prevent module
     reference loops by Linux kernel modules and so making it only find
     symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
     used by Nvidia was to use symbol_get() to purposely swift through
     proprietary module symbols and completely bypass our traditional
     EXPORT_SYMBOL*() annotations and community agreed upon
     restrictions.

     A small set of preamble patches fix up a few symbols which just
     needed adjusting for this on two modules, the rtc ds1685 and the
     networking enetc module. Two other modules just needed some build
     fixing and removal of use of __symbol_get() as they can't ever be
     modular, as was done by Arnd on the ARM pxa module and Christoph
     did on the mmc au1xmmc driver.

     This is a good reminder to us that symbol_get() is just a hack to
     address things which should be fixed through Kconfig at build time
     as was done in the later patches, and so ultimately it should just
     go.

   - Extremely late minor fix for old module layout 055f23b7
     ("module: check for exit sections in layout_sections() instead of
     module_init_section()") by James Morse for arm64. Note that this
     layout thing is old, it is *not* Song Liu's commit ac3b4328
     ("module: replace module_layout with module_memory"). The issue
     however is very odd to run into and so there was no hurry to get
     this in fast.

   - Although the fix did not go through the modules tree I'd like to
     highlight the fix by Peter Zijlstra in commit 54097309
     ("x86/static_call: Fix __static_call_fixup()") now merged in your
     tree which came out of what was originally suspected to be a
     fallout of the the newer module layout changes by Song Liu commit
     ac3b4328 ("module: replace module_layout with module_memory")
     instead of module_init_section()"). Thanks to the report by
     Christian Bricart and the debugging by Song Liu & Peter that turned
     to be noted as a kernel regression in place since v5.19 through
     commit ee88d363 ("x86,static_call: Use alternative RET
     encoding").

     I highlight this to reflect and clarify that we haven't seen more
     fallout from ac3b4328 ("module: replace module_layout with
     module_memory").

   - RISC-V toolchain got mapping symbol support which prefix symbols
     with "$" to help with alignment considerations for disassembly.

     This is used to differentiate between incompatible instruction
     encodings when disassembling. RISC-V just matches what ARM/AARCH64
     did for alignment considerations and Palmer Dabbelt extended
     is_mapping_symbol() to accept these symbols for RISC-V. We already
     had support for this for all architectures but it also checked for
     the second character, the RISC-V check Dabbelt added was just for
     the "$". After a bit of testing and fallout on linux-next and based
     on feedback from Masahiro Yamada it was decided to simplify the
     check and treat the first char "$" as unique for all architectures,
     and so we no make is_mapping_symbol() for all archs if the symbol
     starts with "$".

     The most relevant commit for this for RISC-V on binutils was:

       https://sourceware.org/pipermail/binutils/2021-July/117350.html

   - A late fix by Andrea Righi (today) to make module zstd
     decompression use vmalloc() instead of kmalloc() to account for
     large compressed modules. I suspect we'll see similar things for
     other decompression algorithms soon.

   - samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and
     Chen Jiahao"
