This is a type-correctness cleanup to MMU/boot code that replaces several instances of void * and u64 with phys_addr_t (to represent addresses) and resource_size_t (to represent sizes) to emphasize that the code in question concerns physical memory specifically. The rationale for this change is to improve clarity and readability in a few modules that handle both types (physical and virtual) of address and differentiation is essential. I have left u64 in cases where the address may be either physical or virtual, where the address is exclusively virtual but used in heavy pointer arithmetic, and in cases I may have overlooked. I do not necessarily consider u64 the ideal type in those situations, but it avoids breaking existing semantics in this cleanup. This patch provably has no effect at runtime: I have verified that .text of vmlinux is identical after this change.

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.
