Purpose of this page and table is to evaluate the risk and thus decide about fitness for CSSU kernel, of all patches available from latest KP

Changes:
 2012-11-03 - [freemangordon] Initial draft 
 2012-11-03 - [Joerg_rw] major restructuring to sortable true table, 
                         added coloumns .ko (means only kernel module domain) and 
                         zImg (means massive impact and risk due to edits in kernel core)  
 2012-11-03 - [Pali] added info about Nokia patches and patches disabled in KP
 2013-01-24 - [Pali] updated patches list to match kp52 version
 2013-02-02 - [Pali] updated info about patches
 2013-08-03 - [freemangordon] more patches assessed
                              add underscores around impact in an attempt to make table look better
 2013-08-11 - [Pali] updated info about patches
 2013-10-12 - [Pali] disabled usb host mode patches, updated colors

bq drivers are disabled because are experimental and not working with bme

usb host mode patches are disabled because using bq drivers

overclock patches are disabled because breaking powertop
