Jianxiong Pan 2271989942 mm: pin locked file after fault. [2/2] ...

PD#SWPL-95400

Problem:
If we pin a file in android, the whole data of this file
will be loaded to DDR, but most of these data may not be
used, this caused memory waste.

Solution:
delay mark mlocked flags for unevictable pages until
it has been faulted.
You can use following command to disable this function:
echo 0 > /proc/sys/vm/shrink_unevictable

Verify:
sc2_ah212.
