[Q][Kernel] How to build latest linux kernel for Android device?

​Collegues,
I wonder how to build latest linux kernel from off site for Android device (for example Nexus7)?
I have:
AOSP source code
Android build for device (from aosp)
Downloaded kernel 3.8.4 from off site
The question is:
How can I build latest kernel using all described stuff (aosp source, kernel config, latest kernel)?
Thanks!

[Q] LG L9 Kernel

I have a question about kernel,
Why our kernel stil in 3.0.31? while other device have update to 3.4.1xx,
maybe sir @artas182x @Rammar515 or @sguerrini97 have the answer..
thanks
I remember that artas182x compared gps on 3.0.31 and next version and he said that on 3.0.31 gps works better. For me doing something in kernel is like juping on the fire - still scarred doing something there
It is hard to port 3.4.x kernel to OMAP devices because of problems with drivers. But my kernels have some drivers ported from 3.4.x kernels. Just look how Galaxy Nexus tried to port this kernel. Kernel 3.0.x works great, why we should release unstable kernel.
thanks for the answer sir...
its solve my curiosity...
keep update on lollipop..

Kernel source modification for different android versions

I have the kernel source for JellyBean 4.2.2 that boots cyanogenmod 10 and other jellybean ROMS. But when I use that kernel for Kitkat like Cyanogenmod 11 that doesn't work.
To make sure the problem is in the kernel I packed the cm11 boot.img with the jellybean kernel and it didn't boot.
So my question is what modifications does the source need for a newer android version ?
I posted it many times found no answer .

custom kernel build

do you have to use your device's kernel source to build a custom kernel ??
