CSSU kernel assess

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

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
2013-10-23 - [Pali] added kp53 patches
2013-10-28 - [freemangordon] overclock patches enabled, powertop issue is going to be fixed soon (in powertop)
2013-10-28 - [Pali] added other kp53 patches and missing rx51-battery patch, updated info

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

usb host mode patches are disabled because using bq drivers
