Fix -Wmissing-prototypes warnings:
arch/x86/mm/init.c:81:6:
warning: no previous prototype for ‘x86_has_pat_wp’ [-Wmissing-prototypes]
bool x86_has_pat_wp(void)
arch/x86/mm/init.c:86:22:
warning: no previous prototype for ‘pgprot2cachemode’ [-Wmissing-prototypes]
enum page_cache_mode pgprot2cachemode(pgprot_t pgprot)
by including the respective header containing prototypes. Also fix:
arch/x86/mm/init.c:893:13:
warning: no previous prototype for ‘mem_encrypt_free_decrypted_mem’ [-Wmissing-prototypes]
void __weak mem_encrypt_free_decrypted_mem(void) { }
by making it static inline for the !CONFIG_AMD_MEM_ENCRYPT case. This
warning happens when CONFIG_AMD_MEM_ENCRYPT is not enabled (defconfig
for example):
./arch/x86/include/asm/mem_encrypt.h:80:27:
warning: inline function ‘mem_encrypt_free_decrypted_mem’ declared weak [-Wattributes]
static inline void __weak mem_encrypt_free_decrypted_mem(void) { }
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It's ok to convert to static inline because the function is used only in
x86. Is not shared with other architectures so drop the __weak too.
[ bp: Massage and adjust __weak comments while at it. ]

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.
