We enable CONFIG_RELOCATABLE even when CONFIG_RANDOMIZE_BASE is disabled, and this permits the loader (i.e., EFI) to place the kernel anywhere in physical memory as long as the base address is 64k aligned. This means that the 'KASLR' case described in the header that defines the size of the statically allocated page tables could take effect even when CONFIG_RANDMIZE_BASE=n. So check for CONFIG_RELOCATABLE instead.

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.
