I'm using a SM-P605 with rooted Stock KK-Rom. To get rid of "Enforcing" I first tried to modify the default.prop and init.rc of the ramdisk
as stated http://forum.xda-developers.com/show...487089&page=10 by akshizzle. After reading yout Posts, I commented out the "/dev/mem" and "/dev/kmem" lines from "/file_contexts". After repacking and flashing the boot.img the changes are visible in "/file_contexts", but after running your kmem-script selinux stays on "enforce". I'm not sure if it has to do with the permission-problem on "/dev/kmem", because I don't see any errors (I'm no Linux geek).
The problem I have is mainly the same as on P905, there's no valid kernel-source published for the stock KK rom (P605XXUCNE2 by the way).
Maybe it's a problem with the other ramdisk-changes to init.rc / default.prop, which I didn't revert when editing /file_contexts. Or has there more to be done than commenting out the 2 lines.
With best regards
