SiyahKernel S2-v6.0beta5

Changelog:
thanks to mbwatson@XDA for sending me an international Samsung Galaxy S2. Although the screen is cracked it is perfectly readable and also the touchscreen digitizer is working flawlessly.
based on latest I9100 JB Kernel source
home key is fixed. now it works both in recovery as well as CM10.1 and Samsung ROMs
increased default gpu freqs a little bit. the lowest freq is now 108MHz.
updated SuperSu.
fixed CPU and I/O scheduler changes in STweaks not being applied after reboot.
possible workaround for bootloop bug.
added boot animation support
removed custom CPU steps. the kernel has 6 CPU steps now (1400, 1200, 1000, 800, 500, 200)
fixed stock video player
power saving mode is now working

TODO & Known Problems
dual-boot code (both recovery and ramfs) needs to be refactored to support Samsung JB.
I need to find another trick to get cam working on both Sammy and CM ROMs without losing 50MB+ RAM.
cypress modifications (BLN, BLNWW, touchpad led timeout etc) should be moved to new driver source
needs to be tested more

SiyahKernel S2-v6.0beta4
beta3->beta4: updated wifi module (should fix random reboots that some people experience which is related with wifi). Experimental exfat support (please test and report if exfat formatted external sdcards can be used). fixed headphone amplification. (thanks to lyndonguti and THE RED BLUR for testing this beta)

SiyahKernel S2-v6.0beta3
beta2->beta3: video recording is fixed. fixed mdnie negative effect problem. gpu voltage initialization is fixed

SiyahKernel S2-v6.0beta2
Merged with I9100P JB Sources
Tested only on i9100 jb leak LS6. Not tested on CM10, even if it boots some features (cam, for example) may be broken on cm10.
No dualboot support yet. I will have to update recovery to support that again, but I have no idea when I will have time for that.
Test it only if you are using Samsung’s leaked JB ROM or it won’t boot
Fixed exynos-mem exploit
added ROW I/O Scheduler
using old Wifi driver, this will probably prevent any wifi related lockups/freezes.
default governor: ondemand during betas, and reverted back to legacy hotplug method (pm_hotplug, as Samsung has in JB kernels). reapplied tegrak’s secondcore patches to pm_hotplug and also added governor-awareness to pm_hotplug which will prevent having two different hotplug mechainsms running simultaneously
