This commit adds a new DAMOS action called 'LRU_PRIO' for the physical address space. The action prioritizes pages in the memory regions of the user-specified target access pattern on their LRU lists. This is hence supposed to be used for frequently accessed (hot) memory regions so that hot pages could be more likely protected under memory pressure. Internally, it simply calls 'mark_page_accessed()'.
