The kbuild test robot reported this warning:
arch/x86/kernel/cpu/mce/dev-mcelog.c: In function 'dev_mcelog_init_device':
arch/x86/kernel/cpu/mce/dev-mcelog.c:346:2: warning: 'strncpy' output \
truncated before terminating nul copying 12 bytes from a string of the \
same length [-Wstringop-truncation]
This is accurate, but I don't care that the trailing NUL character isn't
copied. The string being copied is just a magic number signature so that
crash dump tools can be sure they are decoding the right blob of memory.
Use memcpy() instead of strncpy().

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.
