DRIVERS: SLIMBUS: initial overclocking of slimbus .Increase root freq from 11 (24.526MHz) to 31 max (27+MHz) which is the largest it will take .Increase clock gear from 7 to 10 (max again)

This means SLIMbus will use its maximum potential to give the best audio quality for the hardware. Takes advantage of both hardware and the mods from zeroinfinity, also opening the door for more things that were previously limited by this. Researched and experimented by ZeroInfinity and Poondog

ksm: check and skip page, if it is already scanned

On system like Android where most of the process are forked
from parent w/o execve, KSM can scan same page multiple times
in one scan cycle. There is no advantage in scanning same page
multiple times for merging. During testing with Android, it was
observed around 60% pages are skipped for each scan cycle.
