I was able to make a quick build today and try out some cm-10.2. This update has all the recent kgsl updates so keep that in mind when trying this on your rom. I've been running it on the most recent cm nightly and it's been working fine so far. If you're running this, get some undesirable behaviour, and suspect it is because of the kernel, please include logging of some sort in your report. Thanks 
Changes:
- merged in cm/cm-10.2
- merged in proxy exec structures from sched-dl V8
- reinclude -mtune flag for Cortex-A9 (showed steady performance increases overall)
- remove __cpuinit function (https://lkml.org/lkml/2013/5/20/589)
Also, I'm likely to stop supporting 4.2.2 in the very near future, because I already feel I have enough to maintain and after a while of focusing on Harkness, I broke inline kernel compilation with my rom (well I didn't break it, but it won't boot when compiled inline lol and last_kmsg's didn't point to anything directly), so I'm weeding that out in my mainline jb-mr2 branch while maintaining a jb-mr2-exp in parallel, at least until I can get a cleaner branch that is up to date with jb-mr2-exp.

With the new CM11 builds being churned out, I decided to give the 12-08 nightly an install. I had also seen that Juri (jlelli) started up a branch for a new sched-dl ABI on the current Linux mainline kernel, so I decided to work on bringing that over and running my own kernel on top of things. I managed to get a full implementation of -deadline this time around so I thought I'd share.
This build doesn't have all the stuff from the prior version but a handful of things from the previous version(s) got merged this morning (still includes fauxsound, fast charge, off the top of my head).
I'll try getting something more formal out soon as well as redoing the OP with the proper details, etc.
Here's this morning's build if you want to try it out.

This is awesome
loved your kernel. Going to give it a flash now and report backSent from my SAMSUNG-SGH-I747 using XDA Premium 4 mobile app
Is this compatible with 4.3 as well? Didn't know if all linux 3.4 builds could use it

The major factor in compatibility with older builds is the display drivers. I haven't looked at what all changed in that aspect between cm11 and the last cm10.x build, but it might work if its recent. If thats the case, you can try giving it a shot and see how it goes. If it doesn't work, you could always simply reflash your kernel or dirty flash your ROM's zip to restore the stock kernel.

I would imagine it would be okay then. BMS is compatible with both and I'm sure any others should be as long as they are synced after CM's graphic driver change from a month or so ago. Thanks for the info

The update is official. Uploaded my build for this morning, updated the OP, now for a changelog:
- Started over w/ recent CM kernel as a base (includes recent merges from Kernel.org and CodeAurora)
- Fully implemented shed-deadline's new ABI
- Updates to MSM's cpufreq driver from CAF
- Re-branded for axDev
- Re-stripped some modules
- Re-included FauxSound, VoltageControl, FastCharge, -O2/Cortex-A9 optimizations
- Re-implemented patches from TripNRaVeR, franciscofranco, Linux Mainline, ARM, imoseyon, faux123, and plenty more
(I also removed a commit from the last build that seemed to cause some problems with lowmemorykiller after some runtime)
I cut it short since, excluding the new sched-dl, there's a lot of the same (with a good bit removed) and as usual, you can check out github. Gonna try steering clear of a few things this time around, for the sake simplicity and not subtly breaking things.

Here's an early Sunday morning update. I've backported some power efficient workqueue patches from Linaro, which should (as the name implies) save some power, since it allows per-cpu workqueues to be more power-oriented (unbound).
Let me know how it runs.

Normally, I wouldn't post an update after I just asked for status on power consumption without giving everyone a chance to do a good power cycle, but I woke up last night after a couple of hours of sleep and saw I was only up to 96% charge due to charging in low power mode on my stock charger. I think CM might have re-disabled power collapse in an attempt to fix it, but I went ahead and imported some updates to our battery driver from the Samsung 4.3 update just to be safe. So far, my device is charging the way it is meant to (and no low power mode traces from msm_otg yet either). Hopefully, we can get some more accurate results on how well Linaro's unbound wq's work after getting a good night's charge next power cycle.

Not too many changes in this one:
- Merge in changes from CM (CAF merge, kernel.org merge, disable power collapse)
- Update Samsung battery driver
EDIT3: Made up my mind. It IS a bug. And I fixed it (this probably should have been done when CM did its apexq bring-up). Also, I've managed to port over dkp's cool new light features ("breathing" notification light & touchkey backlight animation/touchkey brightness control). This will all be in the next release.

I am about to download this right now. Never mind my sig, I'm currently running LiquidSmooth 2.10 & stock kernel with no other mods. I'll let ya know how it goes after flashing. Thanks for the kernel @Synthetic.Nightmare.
UPDATE: Guess I have to flash a different ROM b/c this version of LS doesn't like any kernel upgrades. Ugh!
DEVICE: SGH-T999 + ROM: LiquidSmooth v2.37 + KERNEL: KT747 + MODS: TKMOD 2.4 = A FREAKIN' BEAST!

Can you confirm this working on D2att? I get nothing but bootloops after flashing over both clean cm11 and quantum
Edit: sometimes it will go as far as a black screen and say systemui has stopped

Friday morning build...
Added a bit more to the OP
12/20/2013 Downloads:

d-h.st
Changelog:
- More uses for power_efficient workqueues [pe_wq]
(Linaro pushed some updates using pe_wq in different areas)
- A couple of sched updates from Linaro
(a couple of things that should help pe_wq work better on dual cores)
- Implement less deprecated Linaro topology implementation with cpupower driver
(the last implementation used a generalized freq table, this one includes a platform-specific config & dual-core specific driver)
- Import semaphore-n4's ondemand cpufreq driver
(cleaned up of a lot of PowerHAL-reliant stuff & tweaked by stratosk w/ input tunables, see OP)
- Set sched_mc_power_savings to 2 by default
(to take advantage of cpu_power driver)
- Merge in cm-11.0
(smart dock changes)
- Increase max readahead to 1024
- Optimize for Cortex-A15 & neon-vfpv4
Strange.
It should work on d2att as long as it's a recent build. The config is set to build for d2att to begin with.
Hard to tell for sure without logs though.

I would post one but to my knowledge you can't logcat during boot can you?

No but if you install the kernel, let it boot up/fail, then right after go into recovery and flash a working backup kernel afterwards, you might be able to catch a last_kmsg [last kernel message] (only thing a logcat might do is tell me whether or not its your ROM thats the problem... And that depends on how far it boots). I use an app called SysLog for quick and easy access to any type of log if you want to try that out and not have to take logs manually.
Also I was almost certain there were a couple of people on d2att that were using this at some point and might still check in. Hopefully they can provide some feedback as well.
If all else fails my gf has a d2att, but she's still running one of my old jelly bean builds on it. Once she gets back home from out of town, I can try setting her up on a kitkat build for some tests.

Ah okay. Don't mind the request then lol. I had a minute to spare so I was gonna look into it really quick. You can also copy and paste the contents to pastebin and post the URL. I'd understand if you don't want to be booting over and over though.

- floating-point & graphite loop optimizations
- cleaned up some modules and debugging
- Tweaked GPIO debounce timing [Increased vol. long press]
- Increased touchscreen sensitivity
- dkp notification/backlight LED fade animations (DecimalMan)
- faux sound support
- patches from a plethora of sources (including franciscofranco, WillDeacon, ConKolihas, etc.)
- fast charge capable (imoseyon)
- UV capable (faux123)
- full sched-deadline implementation (jlelli)
- semaphore n4's conservative & ondemand driver (stratosk)
- Power efficient workqueues (Linaro)

- asm-generic rwsem (Will Deacon)
- Imports from Motorola's msm kernel source:
* always update vfp_current_hw_state when forcing reloading
* fixup to allow sched to play nice with CPU_HOTPLUG
* Krait memutils
* acpuclock-krait: init to max speed (improve boot time)
* lmk/compaction: updates to allow improved/stricter memory management
- I'll add more as I remember
BUG REPORTS:
Please include a kmsg/dmesg to any bug reports: http://code.google.com/p/tegraowners-ics-rom/wiki/How_to_get_logs
If you you are unable to do so for whatever reason, try to use as much detail as possible and give me a way to replicate it, so that I may attempt to log it. Thanks!
NOTES:
- Reserved for notes about bugs.
- Cleared since we seem to be golden with trickstermod and I have yet to have a recent cm build fail on init. Let me know if you find anything.

Should be fine, there haven't been many changes to the cm kernel.
Although, I uploaded another build today.
Direct URL -
http://dl.bintray.com/syntheticnightmar3/rivet/Harkness-Kernel-d2-2014-10-11.zip
Changelog:
- Merge cm-11.0
- Fix-up memutils (import newer patch from moto & clean up)
- Import pskm (Anon-Page KSM: https://code.google.com/p/pksm/)
- ARM updates for branch predictor maintenance
Let me know if there's any issues with it (pksm might need some tuning). Same deal as last time, just built and uploaded (but tested in similar builds). As long as it uploaded alright, it should be fine.7I know it's been a while since I posted a release (after the test) but thats only because I wanted to make sure everything was in tip-top shape and with the amount of adjustments made between then and now, I wanted to have something that was working nicely before releasing. I don't want to say I'll do nightlies, weeklies or even monthlies, due to the fact that I try testing things as intensively as I can and because kernels can take some time before they "settle." But I do want to try releasing more often.
As stated, I've pulled in and made a couple of changes since the test, and there are a few I wanted to touch on and possibly ask your opinion about...
1. I have included the tripndroid iosched by TripNRaVeR. It's based on noop, deadline and vr and meant to have minimal overhead. I would like to know if it would be preferred in place of zen.
2. Harkness is now being compiled using -O2 with Sourcery CodeBench Lite's gcc-4.7.3 toolchain (compiles -O2 cleanly and at the speed of the gcc-4.8 toolchain I was testing out). I went with this one because a post by ezekeel some time ago debunking the effect of optimized toolchains in benchmarking, it seemed this one actually made somewhat of a difference. Though, I have also read that previous revisions of this toolchain can be buggy with neon if I remember right, so I'd like to see if there are any problems with this revision of the toolchain (but after a few days, I've yet to see anything wrong on my current rom).
3. Off this last charge cycle, I've gotten ~20.5 hours with about 5 hours and 16 minutes screen time (screenies at request; they're on my device). Which is something my d2tmo hasn't done before. At least not in recent memory. But that is not the point... I had forgotten to turn off proprietary mpdecision (and raise my auto_hotplug settings for testing), so I'm thinking it's working well enough to do away with auto_hotplug, but I'd like to know opinions on the current implimentation and how it works for you, any preferred settings and whatnot would also be appreciated; that way if it does stay, I can have an idea on some tunings that work (because I can't seem to find a satisfactory one).
Unfortunately, the ondemand/powerHAL combo will have to wait until I get to test some things, but this last cycle worked well with CM's defaults, but the good news is, I've gotten this source to compile with ZER0 warnings. remove-warnings branch has been added to OP if any dev is interested in getting rid of some useless common warnings on cm source.
Ack. Too many words for a forum post. I think that's the important stuff I wanted to cover lol.

Changelog:
- Merged in CM
- Built with CodeSourcery gcc-4.8 (will update script once I get my new CrunchBang setup finalized [so long, Mint])
- Imported some changes to our display/video drivers from the Sprint KK update
I'll fix this up if I need to tomorrow. Gonna knock out now and test the latest changes with a full charge tomorrow.6Finally got around to installing kitkat on my gf's d2att and had the same problem on a clean install @jukiewalsh.
I had to install my rom and gapps first, let it boot, then reboot and install the kernel. CM11 on our devices is buggy on init and I'm thinking that may just be a part of it. Afterwards, it worked as expected.
So now that I have 2 devices to test on with varying usecases, I can find out about things I broke sooner.
And while out of town, I found out my commit for touch_load caused some deep sleep trouble (on occasion, it would get cpu0 as offline and set it that way while the ondemand driver checked the cpu). So I've got a quick update that will likely fix the issue:
12-27-2013 Downloads:

Changelog:
- ondemand: only account for touch_load when cpu0 is online
- Update led touchkey animation to current dkp-4.4 (just because I was here doing things already)
