IMPORTANT: As per notice of 01.11.2013, my CM10.2 kernels do NOT support proprietary Custom Rom frameworks anymore. So if your Custom Rom did not implement the generic framework class framework-2.jar but his own naming convention, you will receive a boot loop. Do not cry about this here but advise your Custom rom cooker to fix this. I will not change this ever again.The most prominent custom kernels for CM will follow the same approach (aligned between Yank555, Googy, LordBoeffla, Psndna, Temasek and me).
So please do pass this message along to your favorite ROM devs.
If they don't fix their rom, it won't be compatible with custom kernels any more!

Kernel App DevilTools: Klick
Bitte beachten:
Dieser Kernel unterstützt nur ROMs von Android-Version 4.3 (Sammy und AOSP) und darüber!
Nutzt ihr den Kernel auf einem AOSP basiertem ROM und möchtet auf einen anderen Kernel wechseln, müsst ihr die ROM nochmal "dirty" flashen um alle geänderten Dateien wiederherzustellen!
Originalthread und Downloads bitte hier lang: Klick
Solltet ihr auf XDA angemeldet sein, vergesst bitte nicht dem Dev DANKE zu klicken. 
Dualboot FAQ - Unbedingt lesen!
Achtung Wichtig: Wenn ihr den Kernel für Dualboot nutzen möchtet, muß
man das Devil CWM Recovery installieren!!
Information über das Recovery:
- Das Recovery mountet /cache, /system or /data nicht Standardmäßig. Wenn ihr das Rom modifizieren wollt (zip instal zb Theme oder MOD, wiping data, erstellen/wiederherstellen von nandroid, fixing permissions,...),
muß mann zuerst in das Dualboot Menü
In diesem Menü kann man:
* erstellen der secondary system partition (Muß man einmal ausführen um eine Sec Rom zu installeren)
* aktiviert mounting des primary filesystem
* aktiviert mounting des secondary filesystem
aktiviert das mounting eines Dateisystems( sec Rom, pri. Rom), alle oben erwähnten Aktionen werden jetzt auf das ausgwählte Dateisystem installiert.
Das Dateisystem bleibt aktiv bis man entweder Rebootet oder im Menü ein anderes Rom mountet.
Install-zip menu:
Ihr werdet ein neues Menu vorfinden, in dem man auswählen kann welche Datei man flashen will !!
wenn Ihr kernel, rom or recovery,wählt wird die zip installiert wie sie ist
wenn Ihr zip to pri./sec. wählt das Dateisystem, it is selfexplanary
wenn Ihr rom to secondary Fs,wählt wird der zip modifiezirt um den zip als sec. fs zu installieren
WILL MAN DIE DATEI WIEDER INSTALLIEREN MUSS MAN DIE DATEI ERNEUT DOWNLOADEN!!!
Wenn man die Datei als Primeri Dateisystem installieren kann man die selbe Datei Verwenden!!!!
Wie installiert man eine second rom:
Bevor ihr eine Sec. Rom installiert geht sicher das Ihr eine Sec. Systempartition erstellt!! dies kann einige Minuten dauern !,5 GB!!
Der sicherste Weg ist ein Nandroid wieder herzustellen!!
Wenn ihr noch keines habt mach jetzt eins.
geht zu Dualboot Menu, enable mounting of primary fs geht zum Nandroid menu und macht ein Nandroid.
geht zurück ins Dualboot menu, enable mounting of secondary fs, danach zum Nandroid menu, und wiederherstellen des Backup.
Nun ist man in der Lage in die beiden Roms zu booten die jetzt natürlich gleich sind!! (bei einem zuvor erstellten Backup natürlich nicht)
!
jetzt kann man eine ander Rom als Primary installieren!
wenn Ihr eine neue Rom direkt als Sec. Rom installiert
geht sicher das kein spaces im Filnamen sind !!!
danach zum CWM Menüpunkt install zip.
Ihr werdet ein neues Menu vorfinden, in dem man auswählen kann
welche Datei (Rom, zip, Kernel...) und auf welche Rom man flashen will !!
Wenn man rom to sec. fs, auswählt wird der Rom zip automatisch bearbeitet um die zip als sec. Rom zu installieren ,
das dauert ein wenig weil die Datei wieder gezipt werden muß!!
Achtung wichtig : this file is permanently modified. if you think you need it later again, you should redownload it, because the modified one would always install as secondary.
installing a rom as primary, a zip to primary or secondary fs, does not modify the zip.
Zusätzliche Informationen
roms coming with an Aroma installer are hard to handle, as every dev can place own commands into it. It's impossible for me, to take care of every possibility. Because of this, it should be the best method, to flash a rom with aroma installer as primary one (and then move it to secondary, by using the nandroid method, if you want it to be secondary).
adb/mtp connections seems not to be working on second rom i still try to find the cause of it, but it seems like no one knows anything about adb
i myself got a working mtp on secondrom, by restoring a nandroid of my sammy rom to secondary fs (for which mtp already was working).

Changelogs:
02.01.2014:
+ merged mk9 source drop

+ fixed gyroscope sensor again
+ reverted Sec Oom Killer (maybe causeing some random reboots)
+ switched to latest linaro toolchain (4.8.3 of 12/2013)
26.12.2013:
+ fixed video recording on aosp roms
25.12.2013:
+ cleanly merged update13 (thx to yank555-lu), my previous merge was messed up
+ addded async fsync by htc (ported by faux123)
+ fixed sensors agqain
24.12.2013:
+ merged samsung update13
+ switched back to O2 compiling mode (smaller kernel image, maybe better stability)
+ hardware keys backlight options working for samsung roms as well now
+ re-added oc up to 2 ghz (for those whos device can handle this, mostly added for note2)
+ re-added devil kernel boot logo
+ updated adbd binary to get rid of countless errors in logcat
+ reverted some config changes which may have introduced gpu crashes
12.12.2013:
+ samsung 4.3 roms: added new additional mountpoint for external sdcard ( /extSdCard)
+ aosp 4.4.x roms: export path of external storage, needed by some apis
+ merged samsung update for note2 (contains fixes for memory management, mali driver, lowmem killer option SEC_OOM_KILLER, new modem driver, ...)
+ backported cpu boost driver
Code:
When certain bursty and important events take place, it might take a while for the current cpufreq governor to notice the new load and react to it. That would result in poor user experience. To alleviate this, the cpu-boost driver boosts the frequency of a CPU for a short duration to maintain good user experience while the governor catches up. Specifically, this commit deals with ensuring that when "important" tasks migrate from a fast CPU to a slow CPU, the frequency of the slow CPU is boosted to be at least as high as the fast CPU for a short duration. Since this driver enforces the boost by hooking into standard cpufreq ADJUST notifiers, it has several advantages: - More portable across kernel versions where the cpufreq internals might have been rewritten. - Governor agnostic and hence works with multiple governors like conservative, ondemand, interactive, etc. - Does not affect the sampling period/logic of existing governors. - Can have the boost period adjusted independent of governor sampling period.
+ improve swap per google's suggestion
+ enabled SEC_OOM_KILLER:
Code:
This enables 'Android-Style oom-killer' The way to select victim by oom-killer provided by linux kernel is totally different from android policy. Hence, it makes more sense that we select the oom victim as android does when LMK is invoked.
+ switched to zswap (backported from linux 3.13) + vnswap instead of zram
03.12.2013:
+ gpu control: voltages are applied as deltas internally (no noticable change for users, this just was needed for the second change below)
+ gpu control: if gpu freq. gets changed by user, only reset its matching voltage, all other voltages stay untouched.
+ reverted adb binary to the one from samsung's 4.3 release (seems to be the most compatible and should fix some mtp issues)
+ disabled: swap, zram, zcache, cleancache and frontswap to see if this fixes lags for some users
30.11.2013 part2:
+ fixed boot for omni rom again
29.11.2013 part2:
+ fixed apllying of custom gpu voltage
+ removed intellyplug driver (wasn't working properly, consumed much battery, made boot up take longer and it was unstable)
29.11.2013:
+ added support for omni rom (primary or secondary)
+ fixed: secondary rom no longer stuck at max freq.
+ n7100: fixed gps
+ gpu control: automatically set voltages according to changend freq (ported from yank555-lu), you can apply your own voltages after you have changed all freq (changing a freq, causes the voltages to be reset again)
recovery: bug fixes, to be sure never to wipe/backup/restore the wrong filesystem
24.11.2013:
+ partial updated mali driver from SEA update 1 (this also fixes a typo in original implementation)
+ properly applied dualsound engine support, boeffla and scoobidoo (unlike other devs, this implementation only allows one sound mod to be active at a time. if you switch on boeffla (in boeffla app for example), scoobidoo gets disabled automatically. if you turn on scoobydoo in deviltools (new option), boeffla gets disabled automatically)
+ fixed hardware keys backlight settings and added more options to Deviltools
+ small mdnie related corrections
+ added gpu control, needs to be set manually for now.
+ ARM: SMP: use a timing out completion for cpu hotplug
+ init.d support for sammy 4.3
+ dualboot support for all supported roms (i couldnt try this. be careful!)

Specifically, this commit deals with ensuring that when "important" tasks migrate from a fast CPU to a slow CPU, the frequency of the slow CPU is boosted to be at least as high as the fast CPU for a short duration. Since this driver enforces the boost by hooking into standard cpufreq ADJUST notifiers, it has several advantages: - More portable across kernel versions where the cpufreq internals might have been rewritten. - Governor agnostic and hence works with multiple governors like conservative, ondemand, interactive, etc. - Does not affect the sampling period/logic of existing governors. - Can have the boost period adjusted independent of governor sampling period.
+ improve swap per google's suggestion
+ enabled SEC_OOM_KILLER:
Code:
This enables 'Android-Style oom-killer' The way to select victim by oom-killer provided by linux kernel is totally different from android policy. Hence, it makes more sense that we select the oom victim as android does when LMK is invoked.
+ switched to zswap (backported from linux 3.13) + vnswap instead of zram
03.12.2013:
+ gpu control: voltages are applied as deltas internally (no noticable change for users, this just was needed for the second change below)
+ gpu control: if gpu freq. gets changed by user, only reset its matching voltage, all other voltages stay untouched.
+ reverted adb binary to the one from samsung's 4.3 release (seems to be the most compatible and should fix some mtp issues)
+ disabled: swap, zram, zcache, cleancache and frontswap to see if this fixes lags for some users
30.11.2013 part2:
+ fixed boot for omni rom again
29.11.2013 part2:
+ fixed apllying of custom gpu voltage
+ removed intellyplug driver (wasn't working properly, consumed much battery, made boot up take longer and it was unstable)
29.11.2013:
+ added support for omni rom (primary or secondary)
+ fixed: secondary rom no longer stuck at max freq.
+ n7100: fixed gps
+ gpu control: automatically set voltages according to changend freq (ported from yank555-lu), you can apply your own voltages after you have changed all freq (changing a freq, causes the voltages to be reset again)
recovery: bug fixes, to be sure never to wipe/backup/restore the wrong filesystem
24.11.2013:
+ partial updated mali driver from SEA update 1 (this also fixes a typo in original implementation)
+ properly applied dualsound engine support, boeffla and scoobidoo (unlike other devs, this implementation only allows one sound mod to be active at a time. if you switch on boeffla (in boeffla app for example), scoobidoo gets disabled automatically. if you turn on scoobydoo in deviltools (new option), boeffla gets disabled automatically)
+ fixed hardware keys backlight settings and added more options to Deviltools
+ small mdnie related corrections
+ added gpu control, needs to be set manually for now.
+ ARM: SMP: use a timing out completion for cpu hotplug
+ init.d support for sammy 4.3
+ dualboot support for all supported roms (i couldnt try this. be careful!)
