mark_screen_rdonly
follow_page_pte
copy_one_ptepy one vm_area from one task to the other. Assumes the page tables* already present in the new task to be cleared in the whole range* covered by this vma.
zap_pte_range
handle_pte_faultThese routines also need to handle stuff like marking pages dirty* and/or accessed for architectures that don't do it in hardware (most* RISC architectures)
__follow_pte_pmd
mincore_pte_range
__munlock_pagevec_fillFill up pagevec for __munlock_pagevec using pte walk* The function expects that the struct page corresponding to @start address is* a non-TPH page already pinned and in the @pvec, and that it belongs to @zone
