x86/mm: Fix -Wmissing-prototypes warnings for arch/x86/mm/init.c
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. ]
