From: Ma Wupeng <mawupeng1@huawei.com>

The first patch cap zone movable's min watermark to small value since no
one can use it.

The second patch introduce a per zone watermark to replace the vanilla
watermark_scale_factor to bring flexibility to tune each zone's
watermark separately and lead to more efficient kswapd.

Each patch's detail information can be seen is its own changelog.

changelog since v1:
- fix compile error if CONFIG_SYSCTL is not enabled
- remove useless function comment
