The tool of Smatch static checker reported the following warning: drivers/edac/i10nm_base.c:364 show_retry_rd_err_log() warn: should bitwise negate be 'ullong'? This warning was due to the bitwise NOT/AND operations between 'status_mask' (a u32 type) and 'log' (a u64 type), which resulted in the high 32 bits of 'log' were cleared. This was a false positive warning, as only the low 32 bits of 'log' was written to the first RRL memory controller register (a u32 type). To improve code sanity, fix this warning by changing 'status_mask' to a u64 type, ensuring it matches the size of 'log' for bitwise operations.

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.
