[PATCH 24/58] mm: include/linux/huge_mm.h: Declare is_vma_temporary_stack unconditionally

From: Josh Triplett
Date: Mon Nov 19 2012 - 00:30:27 EST


include/linux/huge_mm.h declares is_vma_temporary_stack inside an ifdef
CONFIG_TRANSPARENT_HUGEPAGE; however, mm/rmap.c defines the function
unconditionally. Move the function outside of the ifdef.

This eliminates a warning from gcc (-Wmissing-prototypes) and from
Sparse (-Wdecl).

mm/rmap.c:1440:6: warning: no previous prototype for âis_vma_temporary_stackâ [-Wmissing-prototypes]
