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.
