Use the __set_memory_yy() variants instead of set_memory_yy() where useful. This allows to make the code a bit more readable. This also fixes the debug pagealloc case, where set_memory_4k() might be called for an area larger than 8TB which would lead to an overflow of the num_pages parameter of set_memory_4k(). However RELOC_HIDE() has to be used for the __set_memory_4k() case for the time being, to avoid compiler warnings because of performing pointer arithmetic on a NULL pointer, which has undefined behavior. This happens because __va(0) always translates to NULL. However this will change, and as soon as this happens the RELOC_HIDE() hack can be removed again.

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.
