Introduction
Hello everyone, this is a thread to introduce both users and kernel developers to the concept of linux-stable as well as give developers some tips and a tree to either merge into their own, use as a base, or just as a reference. Feel free to ask questions and enjoy!
What is it?
linux-stable is, as the name implies, the stable branch of the Linux kernel, the base of Android. The phone could not run without the Linux kernel (at least not without reworking a lot of stuff). The Android kernels are based on the longterm stable trees:
Longterm
There are usually several "longterm maintenance" kernel releases provided for the purposes of backporting bugfixes for older kernel trees. Only important bugfixes are applied to such kernels and they don't usually see very frequent releases, especially for older trees.

All Linux development happens on the master branch, which is governed by Linus Torvalds. When issues are discovered there, the fixes are applied then backported to these various stable trees for consumption. It is not uncommon for a fix to need to go back a few years.
There is a LOT more information available in the notes repo in the android-linux-stable organization if you care to learn more in-depth: https://github.com/android-linux-stable/notes
What does this mean for me?
If you are a developer, this means you should be merging these changes into your own tree. These are vetted, stable fixes to real world problems and they are being handed out for free. It does not take long to get up to date (as you can just merge this tree directly into your own or do it yourself using the tree as a reference) and once you are up to date, there is usually a release once every two weeks, give or take. I provide a rebuttal to a lot of various complaints here. If you still feel like there is a good reason not to do this, please let me know, I'll be happy to try and debate on it!
If you are a user, it means that you should be looking for and using kernels that have these fixes, as it shows the developers care for your security and stability. The current version for this device is 4.9.65 on OxygenOS 5.x and 4.9.106 on OxygenOS 9.0/Open Beta while the current version upstream is 4.9.135 so all you need to do is go into Settings > About phone and look at the kernel version to know if you are up to date.
How do I use?
If you are a developer, the reference tree is located in the android-linux-stable organization: https://github.com/android-linux-stable/op6
This can either be merged into your existing kernel tree if you have one or be used as a fresh base. You do not need my permission to use it nor do you need to give me credit (although it would be appreciated).
If you are a user, use a kernel that has the changes added in!
Getting notified about updates
There are a few ways to get notified of linux-stable updates:

Getting help
If you have any issues with getting these changes into your tree or want to ask a question, there are a few different ways to do it:
Post in this thread
Join the linux-stable support chat on Telegram: https://t.me/joinchat/C1UAJ1EMSX31PCFdwLnOSg
File an issue either in the android-linux-stable notes repo or the android-linux-stable repo for this device
When requesting help, please give some solid details as to what you are struggling with, as I am happy to provide assistant and clarity but not to do something for you (unless I screwed up).
God damn ! You here ! I'm feeling lucky ! Nexus 6P, Oneplus 5 and now Oneplus 6 damn :')
Thanks for your hard work !
Yea boiii
Imma flashing it rn <3
Thanks
Thank you @nathanchance for your efforts. Much needed for the new 4.9 kernel.
Nice one man!!

Who got 1 star ? really ?
btw, @nathanchance you have 5 star from me, good work ,and it is nice to see you here.
As always, good job with informing users , waiting for your kernel
Thanks a lot! :good:

Ratings mean absolutely nothing and I feel sorry for anyone who puts any stock in them but thanks
My kernel should be out tonight.
Hey, can you explain me we can install upper kernel version on the last firmware? And how to do it if we can?
Thank and good thread!

Flash a kernel that has these changes. At this moment, I am the only one who has done so: https://forum.xda-developers.com/oneplus-6/development/op6-flash-kernel-1-00-t3801652
4.9.109 has been merged in.
Could you please provide instructions on how to flash a kernel?
Earlier, I could just extract the boot.img file from one of the ROM images and then extract+repackage with my built Image.gz-dtb using mkbootimg.
The newer Android ROMs seem to only contain a package.bin file instead.

Easiest way is to temporarily boot TWRP on stock then run
Code:
adb shell dd if=/dev/block/bootdevice/by-name/boot$(getprop ro.boot.slot_suffix) of=/tmp/boot.img
adb pull /tmp/boot.img .
then just unpack like you have before.

I followed your advice with both the original OnePlus 6 kernel source and your android-linux-stable repo. I was able to build the kernel, repack it and flash it, but with both repos, the device is sitting with the bootanimation for about half hour or so. Do both repositories need additional work before it can boot?
I packaged boot.img with the following command:
Code:
mkbootimg --base 0 --pagesize 4096 --kernel_offset 0x00008000 --ramdisk_offset 0x01000000
--second_offset 0x00f00000 --tags_offset 0x00000100

Try using this boot image: https://nathanchance.me/downloads/kernels/op6/stock/oos-5.1.8-boot.img
You may also check out Android Image Kitchen too, that's what I used before TWRP.
First, thanks a ton for taking the time to help me out.
I tried unpacking/repacking with your boot.img file, and that didn't work either. However, your boot.img itself works just fine.
I just realized that my build produces a ton of warnings.
Code:

This is probably why my kernels are failing to boot. I'm essentially following the instructions you laid out on the github issue for this kernel.

That's normal, I've hidden all of the warnings.
https://github.com/nathanchance/op6/commits/1d0f0ea36c0814efa36ef8b5c0c1ad9cb74cfe81
Those were the commits I used for my first boot. There is nothing in there that should be necessary to boot, just to make certain things work.
4.9.110 has been merged in.

I am trying to compile 2.6.32 kernel from samsung opensource.
No matter what compiler I use (I tried prebuilt android sdk, codesourcery,
compiled android gcc-4.4.3 from sources) I always get this error:
fs/binfmt_aout.c: In function 'load_aout_binary':
fs/binfmt_aout.c:271: error: 'SEGMENT_SIZE' undeclared (first use in this function)
Any ideas?

Did you try Sztupy's compact VM? It has all the necessary compliers & other tools.

hm strange. i just compiled the source (which i downloaded 2 weeks ago) with the newsest code-sourcery-lite and it worked well. when did you download the source from samsung? i had a problem some time ago with the eclair sources which was fixed when i re-downloaded the sources some day's later ... possibly a "buggy" snapshot?!
edit: in my fs/binfmt_aout.c file isn't even a constant (used) "SEGMENT_SIZE" ...
I forget how I got around this, but I believe others have had luck using the info
here
Update the Makefile:
NOSTDINC_FLAGS += -nostdinc -isystem $(shell $(CC) -print-file-name=include)
==>
NOSTDINC_FLAGS += -nostdinc -isystem $(shell $(CC) -print-file-name=include) -Dlinux
under linux/include, remove the 2nd SEGMENT_SIZE declaration (sony's) in a.out.h

No, I am compiling under linux using "android SDK", even compiled from source.
I also tried codesourcery SDK (as kernel sources sugest in the README) with no luck.

I also dounwloaded the source a couple of weeks ago. And also tried codesorcery "latest" - like 2010q1 - same thing.
SEGMENT_SIZE is not in binfmt_aout.c, it's in include/linux/a.out.c.
I will try to disable a.out binformat.
BTW, what config did you use to compile?

Hmmm. That's why.
include/linux/a.out.h checks if "linux" is defined, then it checks if __KERNEL__ is defined and then it assigns a value to "SEGMENT_SIZE".
Thanks this was really helpful

if you need any more conformation. editing the MakeFile also worked for me. thank you so much.
For some weeks I've been trying to set up an environment in which I'm able to compile the stock kernel for my LG2X on my own. Following various tips and hints were unsuccessful and several restarts were required until a kernel which was compiled on my own box was running on my phone. Since I had to patch together all the information because there was no complete guide available/findable, I'd like to list here all the steps from the beginning which I had to perform to boot my own compiled kernel. Maybe this is also useful for others. Note: again, this approach is for compiling STOCK kernel sources which are based on the public sources from LG. (The build process for CM is different and cannot be applied to stock kernels)
I began with a freshly installed Ubuntu 11.10 32bit (http://www.ubuntu.com/download/ubuntu/download) running in a VMware virtual machine. In it I entered a shell and switched to root to be able to perform the required actions:
Code:
sudo su -
The next step was to add the package-sources for the cross-compiler toolchain (see next step) and to bring the system up to the latest state.
Code:
add-apt-repository ppa:linaro-maintainers/toolchain
apt-get update
apt-get upgrade
This takes some time but after it's finished I installed the cross-compiler toolchain to be able to compile applications for the LGs ARM platform
Code:
apt-get install gcc-linaro
apt-get install gcc-linaro-arm-linux-gnueabi
After this I've been ready to begin with the source-works. I closed the root-shell and opened up a new one (required to make sure that all paths are correctly set and recognized again). Test it by executing
Code:
arm-linux-gnueabi-gcc --version
When this executed without error I started with downloading the sources for version 20q from http://www.lg.com/global/support/opensource/opensource-detail.jsp?detailCustomerModelCode=LGP990 into a new directory.
When the file 'LGP990_Android_Gingerbread_V20Q.zip' had finished downloading I unzipped the complete package by
Code:
unzip LGP990_Android_Gingerbread_V20Q.zip
resulting in three files. A README, one .tar.gz with the ROM sources and finally one .tar.gz with the kernel sources. To unpack the kernel sources I issued
Code:
tar xvzf P990_Stardop_IFX_GingerBread_V20Q_KERNEL.tar.gz
and the complete LG 20q kernel sources were finally located in a new 'kernel' subdirectory.
The kernel sources themselves are not yet ready to be compiled. This is because LG most probably has a different/special build environment and our standard environment produces errors and unbootable kernels. Some patching is required to succeed to a running kernel.
Firstly the compilation options for the wireless module have to be tweaked as the default settings break compilation at some unused variables in the source. This is set to be just treated as warnings for the wireless-module by applying following patch:
Code:
diff -u -r original/kernel/drivers/net/wireless/bcm4329/Makefile kernel/drivers/net/wireless/bcm4329/Makefile

We're not finished yet. We've to create the correct kernel configuration and (again) apply some patches. I'm not so sure about these changes but the kernel refused to boot on my phone without them. It is again provided by spica1234 and contains a number of changes. I did not research which of these changes allowed to boot since most of them are generally useful and I didn't do the work trying them out one-by-one.

After these patches, were finally ready to compile the kernel
Code:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- STAR_TMUS_REV=TMUS_10 TARGET_STAR_HWREV=TMUS_E TARGET_MODEM=ifx
Now go grab some coffee. This takes a while. When it's finished, the compressed kernel-image is found in
arch/arm/boot/zImage
For the experienced kernel-hackers this might be enough. It wasn't for me and I wanted to have it easily installable like other kernels from the forum. So I downloaded a kernel zip package, eg. the one from spica1234 at http://forum.xda-developers.com/showpost.php?p=18253696&postcount=1
Any version will do as long as the kernel is contained in a .zip archive and installable via CWM. In my case I downloaded the kernel zip in a new directory 'build' and unpacked it.
Code:
unzip HP_2x_RC12-RevOTF-PRO.zip
This creates the subdirectories 'data', 'kernel', 'META-INF' and 'system'. Here we now have to replace the kernel and the kernel-modules with our self-compiled versions.
Code:
cd ~build/kernel
rm zImage
cp ~kernel/arch/arm/bootzImage ./zImage
cd ../system/lib/modules
rm *.ko
find ~kernel/ -name "*.ko" -exec cp '{}' . \;
cd ../../..
One last step, creating the zip which carries the new kernel:
Code:
zip -r -FS new_kernel.zip data/ kernel/ META-INF/ system/
This new_kernel.zip can now be flashed with CWM and should boot without problems.
For easier usage, I've attached the three patched files in the build_set.zip attachment so you don't have to patch the stock files by hand. Just extract it in the kernel directory and overwrite the existing files.
I hope I did not make any error in the compilation of this information and that it can be helpful for the interested reader.
Thanks goes especially to spica1234 and the material which he provided me to come through to a successful boot.
Very good explanation. I wish such useful info available b4 an year for me while i published 1st kernel at samdroid for my older device

Bloody hell! I never realised it took so much to simply compile!!!! (I build JEE systems at work, but we scripted most of it, stuff that used to take a day and half now takes a few minutes).
Excellent guide Kosi! I'm a linux and kernel n00b and I understand your instructions pretty well.
Ubuntu 11 is not the best choice though I currently use it myself. v11 can cause problems, especially when not compiling kernels but compiling Android ROMs.
Ubuntu 10 is the better choice.
Also there is a VMware Android Developer Environment available for download, providing nearly all the necessary tools for compilation preinstalled and set-up.
http://forum.xda-developers.com/showthread.php?t=1386918
You can compile your kernel directly in the virtual machine p.ex. on your Windows 7 PC. That's the way I do it for my kernel. VMware Player is available for free, so you can just run the image.
Also install VMware tools, so you can set up a directory for exchanging files between your Windows Host and the virtual Machine Ubuntu. In this directory I usually paste the compiled kernel for further use under Win7 (making the CWM update ZIPs).
Just note that you should have a dual/quadcore CPU strong enough to host the linux and compile the kernel in an acceptable time (usually it takes me 1-2 minutes for complete kernel compilation under virtual machine ubuntu using -j24 option on make).
Can u guys add a bit in this tutorial, example, at which file / folder need to edit for OCUV, add swap function, enable ext4, etc.. seriously like this thread..

As the topic of this thread is just how to get the stock kernel compiling I won't step into modifying it. Please open a separate thread for that.
Small hints though, OCUV requires deeper code changes, swap and ext4 can just be enabled in the kernel config.
Hey,
I follow the guide, but ubuntu (11.04 64 bit) doesn't find the pack
Code:
apt-get install gcc-linaro
so I can't install the pack
Code:
apt-get install gcc-linaro-arm-linux-gnueabi
Edit: With Ubuntu 11.10, it works.
Has anyone compiled and booted a kernel successfully with this guide? Can't get mine to boot, so before I look any further I'd thought I'd check if anyone else has gotten a workable kernel out of it.

Ubuntu 11.xx is still a good choise if you want to build ROMs it is very easy to set it up (it is just one step more then on 10.xx)
i also use ubuntu 11.10 and it is working fine for me with building android ROMs
and of course it can take 1-2 minutes but it also can take up to an hour for a kernel to compile
it all depends on how good your computer is
on my home computer i build a kernel in a matter of seconds (clobber builds)
but when i am at my girlfriend my build (also clobber) on her craptop will take up to 20 minutes
nice guide kosi2801!

Yap. This
Code:
arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.6.2-14ubuntu2~ppa1) 4.6.2
to be specific.
Trymhanson, Try to downgrade with 4.5.3. 4.6.2 is causing this unable to boot issue which was not happening earlier with 4.6.1
try this
apt-get install gcc-4.5-arm-linux-gnueabi
apt-get install g++-4.5-arm-linux-gnueabi
rm /usr/bin/arm-linux-gnueabi-gcc
ln -s /usr/bin/arm-linux-gnueabi-gcc-4.5 /usr/bin/arm-linux-gnueabi-gcc
Thanks, that did it. I also had to change the -Ofast flag back to -O2 as -Ofast wasn't recognized by the 4.5.3 version. So now I'm thinking maybe the -Ofast flag was to blame, so I'll try a fresh 4.6.2 install with -O2. Thanks again.

no may be ofast is not to blame but 4.6.2. Ofast was introduced with 4.6.0 and doesnt work with < 4..6. 4.6.2 doesnt even work with o2. And IMHO kernel compiled with 4.5.3 ismore stable

It wont work with CM but only stock v20q

For anyone interested, currently I'm building with

For my usage patterns the kernel works pretty well, but YMMV.
Thanks spica for the updated patch!

Hi,
see if these works:
First, check if in cm\device folder there is "semc\anzu\..."
if not, local manifest should be changed
if there is anzu folder in cm\device\ then try one of these:
breakfast cm_anzu
breakfast cm_anzu-eng
or alternatively just type lunch and select anzu from the list

The git fetch line fixed it indeed :good: I did need to remove the hardware/qcom/gps/librpc folder though, so that was a smart move

Anyway... ROM compile still running... I'm afraid to stop it, but I forgot to add export USE_CCACHE=1 and to have brunch run with a -j3 switch (which will enable it to use multicore systems)...
It's been running since 7:30 AM (GMT+1) ...
-- EDIT --
If you use the -j switch, take the amount of cores and add 1 to determine the number of threads it can handle. For every 4 cores you can add 1 extra thread. So a dual-core CPU can handle 3, a quad-core can handle 5 but an octo-core can handle 10.
Don't mix up HYPERTHREADING (HT) with actual number of cores, if you have a Pentium series CPU with HT, half the number of cores you might see in your /proc/cpuinfo, HT is doubling your core count but while compiling, it will hinder the processing power of your CPU more then it helps
That clearly does not work on lunch,brunch and breakfast ... too bad!
:victory: FINALY it was done ... or so I thought...

Need help
Hello,
I try to port bcmon to CyanogenMod 11, by building the custom bcmon (bcm4329) kernel module for CM11. As modules are very dependent on the kernel version and configuration (unknown symbol errors even when compiled on the same exact kernel version), I have no other choice but to build the full CM11 kernel.
So I've built a CyanogenMod 11 kernel directly from the kernel source (ARIES kernel), NOT from the full CyanoGenMod system source (which is about 20GB source files, much more for built files, and takes hours to build [tutorial here]).
After some debugs, I managed to get the kernel zImage and .ko modules.
- fbmem.c has an issue with relative samsung/s3cfb.h path: make it absolute
- other bugs listed here (post end)
I also managed to build a ramdisk (initramfs) by manually builing it from the source files in aries usr/galaxysmtd_initramfs_files folder.
I used boot.img "kitchen" tool.
Code:
./repack_ramdisk galaxysmtd_initramfs_files ramdisk.gz
Still, I can't manage to build a proper boot.img with these files. Of course, building a boot.img file "works":
Code:
mkbootimg --cmdline 'no_console_suspend=1 console=null' --kernel zImage --ramdisk ramdisk.gz -o boot-new.img
Indeed I feel this file is gonna screw up my device boot (at least there will still be the recovery...).
Why? Because I believe Galaxy S boot.img is different than from other devices. And that seems to be an issue for other developers as well:

Since I don't know how to unpack & repack boot.img on cm-10.1, I use stratosk ramdisk with some modification to suite my needs.

From this thread @ ubuntu-phone team mailing list archive:
Alistair Buxton said:
from http://wiki.sourcemage.org/HowTo(2f)Initramfs.html and http://comments.gmane.org/gmane.linux.kernel/1027539 this does indeed appear to be a built in initramfs inside the zImage. This is different to the way most android devices use mkbootimg to combine a zImage and ramdisk. In a real CyanogenMod rom for galaxysmtd, boot.img is not a mkbootimg image, nor is it it my earlier ubuntu-touch port. The offsets in System.map seem to be before compression, so perhaps this isn't the whole story, but for sure both kernels have an initramfs with different contents, and nothing else gets added later.

Kitchen tools and unpack-bootimg.pl just don't understand how boot.img file is structured for galaxy S1.

Found a secondary file after the ramdisk image. According to the spec (mkbootimg.h) this file can exist, but this script is not designed to deal with this scenario.
Tried to split the existing device boot.img from CWM full backup... (7MB)
Code:
$ adb pull /storage/sdcard1/clockworkmod/backup/.../boot.img

$ ./split_boot boot.img
Android Magic not found in boot.img. Giving up.
$ ./unpack_bootimg.pl boot.img
Could not find any embedded ramdisk images. Are you sure this is a full boot image?
So how do you exactly create a boot.img from a kernel zImage on Galaxy S1?
Without letting the CyanogenMod magic works with the hassle of compiling the whole CyanogenMod android system files...
NB: By the way, I try to just compile the kernel from full CM system source as per official instructions... and of course it failed.

check this:
https://github.com/didhiy/ramdisk-aries
I use a script for i9100 from chirayudesai github (already deleted), it works for extracting i9000 boot.img
unfortunately in newer lzma version (I'm on ubuntu precise), the script failed
my way to solve the problem is use lzma binary from older version (natty)
the newer version of lzma only soft linked to xz binary, so I removed lzma, lzmainfo & unlzma from /usr/bin/
put lzma & lzmainfo binaries from natty, last create unlzma softlink to lzma binary
Thanks didhiy.
Finally I abandoned the idea to build the kernel alone, this is deprecated by CyanogenMod since CM9.
But CyanogenMod IRC users gave me the following tip to avoid the long android system build. Instead of brunch'ing CM, we can just compile the kernel boot.img directly from source by using the following command (after having setup the whole CM build environment etc.).
Code:
mka bootimage
I've edited the CyanogenMod wiki to explain all this in details:
CyanogenMod wiki: Integrated Kernel Building
i have the same exact problem for a while!
hi,
im happy ive found this topic,but sad to find out u abandoned the idea
my problem is,i dont have enough hard drive on system,(beside the awful internet speed), so i dont want to download the whole 20GB!...
so i preferred to download just some of dependencies which is described in an xml file...
so,all in all,do u know which packages is needed to compile just the boot.img,and not the whole rom zip file?
Just got a T280 - would like to get Nougat on it. I saw @jedld did awesome work on T285 and @_mone did with TWRP, however, I was hoping to create a thread to consolidate any ongoing efforts for T280 in one place, and see where I could help.
This is what I know of the state of the T280 development.
TWRP and root has been available for the T280 for some time, almost at the same time the T285 version has. There is no non-stock based rom available yet.
Custom T280 kernel here courtesy of @_mone, there are reports that it works with an updated T280 stock firmware.
Before flashing a generated boot.img note that it requires special headers for the T280 here: https://forum.xda-developers.com/showpost.php?p=68843058&postcount=81. There is at least one developer in this forum that is looking to make this process easier.
Assumming this works with the T280 stock firmware, the steps that I see are the following:
1. Patch the N and M related linux kernel patches to the T280 kernel http://jeffvanderstoep.blogspot.com/2016/05/selinux-kernel-patches-for-android-n.html. Update the arm defconfig to the latest recommended by android.
2. Create a lineage device tree, you can use my gtexslte manifest as a starting point https://github.com/jedld/android.git. Probably just need to take out the RIL related modules.
awesome - i'll give this a go.. right now I'm just testing building samsung's stock opensource kernel.
It's people like you that make me love xda. Thanks!

You can start by renaming gtexslte to gtexswifi, I believe flash partitions sizes and mountpoints are about the same for both SM-T285 and SM-T280 so you don't need to change much. You probably need to remove phone related configs. You also need to use the SM-T280 kernel also. I don't know if there are other hardware differences from the T280 and T285 (gps?) If this is your first time doing any sort of porting, this can be a daunting task, so I suggest you try to learn how to extract the stock boot and system images, modify some files and then flash it back as an exercise. There might already be a gtexswifi device tree in progress somewhere, I suggest that you contact those devs or probably set up an irc channel to coordinate your efforts.
@jedld - I'm confused - for the M/N Patches to the kernel, it seems like 2 sets of patches undo each other, namely:
Revert "SELinux: per-command whitelisting of ioctls" - https://android-review.googlesource.com/162275
selinux: extended permissions for ioctls - https://android-review.googlesource.com/162279
and
Revert "security: lsm_audit: add ioctl specific auditing" - https://android-review.googlesource.com/162276
security: add ioctl specific auditing to lsm_audit - https://android-review.googlesource.com/162278
What'd you do for those?

I ignored the reverts at first. I can't remember if it worked after that. Though I ended up just doing a straight diff with the selinux modules based on the aosp 3.10.y kernel sources and just merging them.

You need so sync up the kernel ion drivers and include files with the one used by the gtexslte
Pardon my stupidity, but from your post here with the custom t280 header, how would I go about modifying the degas-mkbootimg command with the permissive kernel that I have?

best approach I believe would be to leave mkbootimg as is and just create another commandline utility that takes an exisitng boot.img and prepend the T280 header to it. I'll try to create a C program that does it if I have time.

I'll clone your repo & add something to repack the t280 boot.img. Sorry - had to read through that post a few times - didn't realize the seandroid header was at the end of the file..
Kernel question : the zImage I compile is ~ 5 megs (Image is ~12) - when i unpack the stock boot.img (or the ones that @_mone made), they're around ~10 megs. Any ideas?

I'll clone your repo & add something to repack the t280 boot.img. Sorry - had to read through that post a few times - didn't realize the seandroid header was at the end of the file..

boot.img also contains the ramdisk aside from the compressed kernel image.

best approach I believe would be to leave mkbootimg as is and just create another commandline utility that takes an exisitng boot.img and prepend the T280 header to it. I'll try to create a C program that does it if I have time.

Right, but I'm talking about zImage.. doesn't that remain untouched?

If you are comparing to stock size, samsung might have less flags enabled when they built their kernel as compared to the sources available to us so it could be smaller

I don't know - I merged most of your def config to mine, and rebuilt stock, _mone, the modified one ive been working on, and your performance_2 branch for the t285 - all the zImages are around 5 MB :

For the gtexslte the size is about similar as well:
[email protected]:~/android-work/kernel/samsung/gtexslte/arch$ ls -la arm/boot/*Image*
-rwxrwxr-x 1 jedld jedld 12672968 Aug 28 07:00 arm/boot/Image

Alright.. I'll try that.. and just to make sure, you repack zImage not image right? Just curious why when I unpack _mone it's 2x the size
