[PATCH 01/20] sh: pgtable: Fix missing prototypes

[Geert Uytterhoeven <geert+renesas@glider.be>]

arch/sh/mm/pgtable.c:12:6: warning: no previous prototype for 'pgd_ctor' [-Wmissing-prototypes]
arch/sh/mm/pgtable.c:34:8: warning: no previous prototype for 'pgd_alloc' [-Wmissing-prototypes]
arch/sh/mm/pgtable.c:39:6: warning: no previous prototype for 'pgd_free' [-Wmissing-prototypes]
arch/sh/mm/pgtable.c:45:6: warning: no previous prototype for 'pud_populate' [-Wmissing-prototypes]
arch/sh/mm/pgtable.c:50:8: warning: no previous prototype for 'pmd_alloc_one' [-Wmissing-prototypes]
arch/sh/mm/pgtable.c:55:6: warning: no previous prototype for 'pmd_free' [-Wmissing-prototypes]

Make pgd_ctor() static, as it is only used in this file.
Include <asm/pgalloc.h> to fix the other warnings.
