Pull CRC updates from Eric Biggers:
"Another set of improvements to the kernel's CRC (cyclic redundancy
check) code:
- Rework the CRC64 library functions to be directly optimized, like
what I did last cycle for the CRC32 and CRC-T10DIF library
functions
- Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
support and acceleration for crc64_be and crc64_nvme
- Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
crc_t10dif, crc64_be, and crc64_nvme
- Remove crc_t10dif and crc64_rocksoft from the crypto API, since
they are no longer needed there
- Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect
- Add kunit test cases for crc64_nvme and crc7
- Eliminate redundant functions for calculating the Castagnoli CRC32,
settling on just crc32c()
- Remove unnecessary prompts from some of the CRC kconfig options
- Further optimize the x86 crc32c code"

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.
