mm: introduce page_vma_mapped_walk()
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.
