SeongJae Park 99cdc2cd18 mm/damon/schemes: add 'LRU_DEPRIO' action 
This commit adds a new DAMON-based operation scheme action called
'LRU_DEPRIO' for physical address space.  The action deprioritizes pages
in the memory area of the target access pattern on their LRU lists.  This
is hence supposed to be used for rarely accessed (cold) memory regions so
that cold pages could be more likely reclaimed first under memory
pressure.  Internally, it simply calls 'lru_deactivate()'.

Using this with 'LRU_PRIO' action for hot pages, users can proactively
sort LRU lists based on the access pattern.  That is, it can make the LRU
lists somewhat more trustworthy source of access temperature.  As a
result, efficiency of LRU-lists based mechanisms including the reclamation
target selection could be improved.
