qcacmn: Not to be hard to make high order page
kcompactd consumes many CPU cycles without being successful
to make high-order page. One of the reason is WIFI driver is
allocating order-3 page a lot.
It shows 46% high-order allocation comes from WIFI driver.
Of course, it should be fixed in MM layer but it is never
easy stuff to fix in near future.
Regardless of MM changes, drivers should do best effort to reduce
high-order allocation, too.
This patch fixes the problem via not waking kcompactd.
