When CONFIG_RANDOMIZE_BASE=y, module_alloc_base is a variable which is configured by kaslr_module_init() in kaslr.c, and otherwise it is an expression defined in module.h. As kaslr_module_init() is no longer tightly coupled with the KASLR initialization code, we can centralize this in module.c. This patch moves kaslr_module_init() to module.c, making module_alloc_base a static variable, and removing redundant includes from kaslr.c. For the defintion of struct arm64_ftr_override we must include <asm/cpufeature.h>, which was previously included transitively via another header. There should be no functional change as a result of this patch.

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.
