crc32c_arch() is affected by https://github.com/llvm/llvm-project/issues/20571 where clang unnecessarily spills the inputs to "rm"-constrained operands to the stack. Replace "rm" with ASM_INPUT_RM which partially works around this by expanding to "r" when the compiler is clang. This results in better code generation with clang, though still not optimal.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
