zzmoove 0.6 - flexibility (in cooperation with Yank555)
Changelog:

       - removed fixed scaling lookup tables and use the system frequency table instead
         changed scaling logic accordingly for this modification (thx and credits to Yank555)
       - reduced new hotplug logic loop to a minimum
       - again try to fix stuck issues by using seperate hotplug functions out of dbs_check_cpu (credits to ktoonesz)
       - added support for 2 and 8 core systems and added automatic detection of cores were it is needed
         (for setting the different core modes you can use the macro 'MAX_CORES'. possible values are: 2,4 or 8, default are 4 cores)
         reduced core threshold defaults to only one up/down default and use an array to hold all threshold values
       - fixed some mistakes in 'frequency tuneables' (Yank555):
         stop looping once the frequency has been found
         return invalid error if new frequency is not found in the frequency table
Merge branch 'test' of github.com:temasek/android_kernel_samsung_smdk4412 into cm-10.1
