__kunmap_ {local,atomic}() currently take pointers to void. However, this is semantically incorrect, since these functions do not change the memory their arguments point to. Therefore, make this semantics explicit by modifying the __kunmap_{local,atomic}() prototypes to take pointers to const void. As a side effect, compilers may produce more efficient 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 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.
