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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
