Since ion alloc can be called by userspace,eg gralloc.
When it is called frequently, the efficiency of kswapd is
to low. And the reclaimed memory is too lower. In this way,
the kswapd can use to much cpu resources.

staging: lowmemorykiller: Make default lowmemorykiller debug message useful
lowmemorykiller debug messages are inscrutable and mostly useful
for debugging the lowmemorykiller, not explaining why a process
was killed. Make the messages more useful by prefixing them
with "lowmemorykiller: " and explaining in more readable terms
what was killed, who it was killed for, and why it was killed.
The messages now look like:
[ 76.997631] lowmemorykiller: Killing 'droid.gallery3d' (2172), adj 1000,
[ 76.997635] to free 27436kB on behalf of 'kswapd0' (29) because
[ 76.997638] cache 122624kB is below limit 122880kB for oom_score_adj 1000
[ 76.997641] Free memory is -53356kB above reserved
A negative number for free memory above reserved means some of the
reserved memory has been used and is being regenerated by kswapd,
which is likely what called the shrinkers.
