[PATCH] mm: Mark create_huge_pmd() inline to prevent build failure

[Geert Uytterhoeven]

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'

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()")

Interestingly, create_huge_pmd() is emitted in the assembler output, but
never called.
