This kernel is only for Samsung JB ROM (No ICS support anymore). Although the kernel boots CM10.1 I will not support it until I fix dualbooting.
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

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)
KNOWN PROBLEMS: startup scripts are not executed. reason is unknown until I find another s2 or somebody point out my mistake. side-effects: stweak settings are not applied on boot, headphone amplification doesn’t work and some script-based optimizations are not applied hence the performance is not as high as expected. this may be fixed in beta3, or not. please report if stweaks settings (governor change for example) are applied or not.

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

Register or LoginChangelog:
-Dual booting with new CM10 + Samsung ICS ROM
-improved touch sensitivity
-5-step GPU
-added arm topology patches again, with cpupower driver.
-merged with a JB leak (3.0.31)
-removed dynamic cpu freq steps. they are all fixed now.
-removed some settings from ExTweaks interface such as cfstweaks
-orbot is now working (only tested on Samsung ROM)
-Reboot into 1stROM, Reboot into 2ndROM in STweaks. (v5.0a2)
-STweaks added to initramfs. it will be autoinstalled only once. it is my own implementation of uci.sh interface. There is almost no difference (except for resetting to defaults in the last tab) between ExTweaks and STweaks. It’s been used for some time in my S3 kernel and fairly stable. I wanted to put it in the last version of my S2 kernel as well. it is my second android app (first one is FastDormancy app).. it doesn’t have a fancy UI but not bad for a beginner .
-BLNWW (BLN Without Wakelock).
-Touch gestures optimizations (thanks to Tungstwenty for the latest changes and for this great feature).
-added speaker and mic amplification/sensitivity settings which are based on fluxi’s mc1n2 interface, reversed and ported to uci.sh interface by dorimanx, tested and committed to my initramfs by robertobsc.
-automatic led brightness level. touch voltage level will be ignored if this one is checked in STweaks
-added B2G support (thanks to atilag@github for the initramfs changes).
-added an option in STweaks to set a delay in FB earlysuspend to properly play CRT animation (implemented originally by Codeworkx).
-reverted wifi driver to the one in cm10 kernel
-fixed auto-brightness issue on CM10.
-fixed some 2ndROM related problems in recovery when installing zips or restoring backups
-fixed BLN intensity when auto led brightness is selected.
-applied latest lulzactiveq tweaks from robertobsc.
-mali and vsync related changes (mostly from Entropy512′s commits) which are supposed to improve the battery life
-removed battery and performance profiles.
-removed lots of cpu governors. available governors: pegasusq, ondemand, conservative, hotplug, lulzactiveq
-new optional GPU frequency steps. enable VPLL Mode in STweaks but make sure you read the description.
-fixed a CM10 specific problem with the new GPU steps but it still doesn’t guarantee that the new steps will be stable on your device.
-added slide2wake (thanks to Fluxi) + some optimizations
-added mdnie interface and made hardcore’s sharpness tweaks optional in STweaks
-lulzactiveq fixes by robertobsc and added cpu governor selection back to stweaks
-Finally fixed vpll problem and made it default (thanks to robertobsc for his helps on testing)
