Qian Cai 0cfaee2af3 include/asm-generic/5level-fixup.h: fix variable 'p4d' set but not used 
A compiler throws a warning on an arm64 system since commit 9849a5697d
("arch, mm: convert all architectures to use 5level-fixup.h"),

  mm/kasan/init.c: In function 'kasan_free_p4d':
  mm/kasan/init.c:344:9: warning: variable 'p4d' set but not used [-Wunused-but-set-variable]
   p4d_t *p4d;
          ^~~

because p4d_none() in "5level-fixup.h" is compiled away while it is a
static inline function in "pgtable-nopud.h".

However, if converted p4d_none() to a static inline there, powerpc would
be unhappy as it reads those in assembler language in
"arch/powerpc/include/asm/book3s/64/pgtable.h", so it needs to skip
assembly include for the static inline C function.

While at it, converted a few similar functions to be consistent with the
ones in "pgtable-nopud.h".

README 

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.
