32f6271dbd mm/hugetlb: is_vm_hugetlb_page() can return bool 
Make is_vm_hugetlb_page() return bool to improve readability due to this
particular function only using either one or zero as its return value.

ca16d140af mm: don't access vm_flags as 'int' 
The type of vma->vm_flags is 'unsigned long'. Neither 'int' nor
'unsigned int'. This patch fixes such misuse.

[ Changed to use a typedef - we'll extend it to cover more cases
  later, since there has been discussion about making it a 64-bit
  type..                      - Linus ]

e3390f67a7 hwpoison: rename CONFIG 
CONFIG_HUGETLBFS controls hugetlbfs interface code.
OTOH, CONFIG_HUGETLB_PAGE controls hugepage management code.
So we should use CONFIG_HUGETLB_PAGE here.

8edf344c66 hugetlb: move definition of is_vm_hugetlb_page() to hugepage_inline.h 
is_vm_hugetlb_page() is a widely used inline function to insert hooks
into hugetlb code.
But we can't use it in pagemap.h because of circular dependency of
the header files. This patch removes this limitation.
