Subject: mm: move is_vma_temporary_stack() declaration to huge_mm.h
X-Git-Tag: v3.5-rc1~49^2~146
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2099597401c7710c00b0d7c32b24a44a193836e1;p=pandora-kernel.git

mm: move is_vma_temporary_stack() declaration to huge_mm.h

When transparent_hugepage_enabled() is used outside mm/, such as in
arch/x86/xx/tlb.c:

+       if (!cpu_has_invlpg || vma->vm_flags & VM_HUGETLB
+                       || transparent_hugepage_enabled(vma)) {
+               flush_tlb_mm(vma->vm_mm);

is_vma_temporary_stack() isn't referenced in huge_mm.h, so it has compile
errors:

  arch/x86/mm/tlb.c: In function `flush_tlb_range':
  arch/x86/mm/tlb.c:324:4: error: implicit declaration of function `is_vma_temporary_stack' [-Werror=implicit-function-declaration]

Since is_vma_temporay_stack() is just used in rmap.c and huge_memory.c, it
is better to move it to huge_mm.h from rmap.h to avoid such errors.
