*	mm: convert page_mapped_in_vma() to use page_vma_mapped_walk()	Kirill A. Shutemov	2017-02-24	1	-0/+30
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	For consistency, it worth converting all page_check_address() to page_vma_mapped_walk(), so we could drop the former.

*	mm: introduce page_vma_mapped_walk()	Kirill A. Shutemov	2017-02-24	1	-0/+188
	Introduce a new interface to check if a page is mapped into a vma. It aims to address shortcomings of page_check_address{,_transhuge}. Existing interface is not able to handle PTE-mapped THPs: it only finds the first PTE. The rest lefted unnoticed. page_vma_mapped_walk() iterates over all possible mapping of the page in the vma.
