Not all LoongArch processors support CRC32 instructions. This feature is indicated by CPUCFG1.CRC32 (Bit25) but it is wrongly defined in the previous versions of the ISA manual (and so does in loongarch.h). The CRC32 feature is set unconditionally now, so fix it. BTW, expose the CRC32 feature in /proc/cpuinfo. Cc: stable@vger.kernel.org Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
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 Restructured Text 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.
