How to Upstream Android kernel? My upstreamed Android kernel

What is a linux kernel?

The linux kernel Organization is a California Public Benefit Corporation established in 2002 to distribute the linux kernel & other opensource software to the public without charge. The linux kernel org is maintained by The linux foundation

Why linux kernel is only used in Android Devices?

'Linux kernel is an open source project' which means every one can make enhancements upon the linux kernel. so, Android takes linux kernel as its underlying kernel & makes enhancements to meet mobile o/s requirements . Like better memory optimisation, Ram management & better performance.

So, Now How To Upstream Android Kernel?

For this u had to be familiar with git commands ( https://try.github.io/ ) & how to compile android kernel
Now Figure what kernel version u are using for this check Makefile in ur kernel tree

Then Fetch the kernel from kernel.org

For latest kernel tag & patches check https://www.kernel.org/
Now iam upstreaming my kernel from v3.10.107 to v3.10.108

Now Simply copy paste the commands as follows,

git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git v3.10.108

Now decide if u want to cherry-pick or merge

-Cherry-pick
Pros:-

1. Easier to rebase
   2)Easier to resolve conflicts as uk what conflit is causng issues
   Cons:-
   1)It takes long time cuz each commit has to be individually picked
   -Merge
   Pros:-
   1)Its faster
   Cons:-
2. Its difficult to resolve conflicts
   2)Rebasing is difficult
   I would recommend u to do cherry-pick

Now After fetching ,

Cherry-pick

Format:

git cherry-pick <previous_tag>..<next_tag>

example:-

git cherry-pick v3.10.107..v3.10.108

Merge

Format:

git merge <next_tag>

example:-

git merge v3.10.108
