The main task

# Download to toolchain and kernel sources
# Please follow and do step by step

# Kernel sources size about 1Gb (kernel 3.0.31+ for omap4470), for android JB 4.2.2
git clone https://github.com/DenZxd/android_kernel_sd_x7 -b omap-mr1

# Toolchain size 218 Mb
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6

# For zImage packing lzop and uImage package needed:
sudo apt-get install lzop
sudo apt-get install uboot-mkimage

________________________________________
# command for compilation and next

# go to parent of kernel folder

export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=/home/XXXXXXXXX/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-

# XXXXXXXXX - your path to toolchain

make panda_X7_defconfig
make menuconfig

# inside config set INITRAMFS_SOURCE to initramfs (folder "initramfs" without quotes must be in parent folder of kernel sources)
# CONFIG_INITRAMFS_SOURCE="initramfs"
# and save config settings

make uImage 2>&1 |tee log

!!!!!!!
if after start compilation the warnings appear and log different from log there ("old good compiled kernel log" on pastebin - is successfully work kernel log )
http://pastebin.com/neGWt2UF
kernel builds successful, but with warnings
its will not work after flash on device
________________________________________
# clear all if compilation is not successfull
make dep
make clean
make mrproper


The main task:

1. Successful build uImage without any warnings. (ready for test it)
2. Build new uImage and uImage_recovery for СМ 12.1 (ramdisks are compiled and ready now). СМ12.1 rom is compiled, but not tested because boot and recovery is absent.
3. partition size on device:
   boot (uImage) - 6,3 mb
   recovery (uImage_recovery) - 8,4 mb
4. the structure of my image (for example on uImage)
initramfs without packing injected in Image
Image packed with lzop and injected in zImage
zImage wrapped to uImage
Сonclusion: Due to the fact packing in image is only ones (only for image, ramdisk not packed) ramdisk size is very critical!!!!!

on my pastebin:
http://pastebin.com/u/DenZpb
present all logs from compiling, start, and stop kernel:
dmesg.log
event.log
last_kmsg.log
logcat.log
and etc.
