Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings. Move the function down in the file so __pa() exists in our scope, and it compiles. This in turn requires moving __pa() as it depends on __virt_to_phys() that was below. (Lazy macro evaluation conflicts with strict function ordering.) Make a symmetric change to pfn_to_virt() so we have type checking both ways. Due to this the <asm/page.h> file being included into some assembly files, some further inclusion guards are needed to make sure assembly keeps compiling.

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.
