From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
Subject: mm/memory.c: mark create_huge_pmd() inline to prevent build failure
With gcc 4.1.2:
mm/memory.o: In function `create_huge_pmd':
memory.c:(.text+0x93e): undefined reference to `do_huge_pmd_anonymous_page'
Interestingly, create_huge_pmd() is emitted in the assembler output, but
never called.
Converting transparent_hugepage_enabled() from a macro to a static
inline function reduced the ability of the compiler to remove unused
code.
Fix this by marking create_huge_pmd() inline.
Fixes: 16981d763501c0e0 ("mm: improve readability of transparent_hugepage_enabled()")
