How to bump kernel version
==========================

Parameters:
-----------
* branch to upgrade to (example: linux-3.14.y as defined on git.kernel.org)
* tag to upgrade to (example: v3.14.14)
* kernel version

Define variables:
# linux_branch=linux-3.14.y
# linux_tag=v3.14.19

1. Clone kernel-common
----------------------

# git clone review.tizen.org:profile/common/kernel-common
# cd kernel-common

2. add kernel.org as new origin and fetch it
--------------------------------------------

# git remote add linux_stable git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
# git fetch linux_stable

3. import on upstream branch until given revision and push to tizen.org
-----------------------------------------------------------------------

# git fetch origin
# git checkout upstream
# git rebase linux_stable/${linux_branch}
# git push origin HEAD:upstream
# git push --tags origin HEAD:upstream

4. rebase tizen branch
----------------------

# git checkout -B tizen origin/tizen
# git rebase -i ${linux_tag}

5. update kernel config
-----------------------

# make ARCH=i386 common_x86_defconfig
# make ARCH=i386 menuconfig
# ... change config ...
# make ARCH=i386 savedefconfig
# mv defconfig arch/x86/configs/common_x86_defconfig

# make ARCH=x86_64 common_x86_64_defconfig
# make ARCH=x86_64 menuconfig
# ... change config ...
# make ARCH=x86_64 savedefconfig
# mv defconfig arch/x86/configs/common_x86_64_defconfig

# make ARCH=arm tizen_defconfig
# make ARCH=arm menuconfig
# ... change config ...
# make ARCH=arm savedefconfig
# mv defconfig arch/arm/configs/tizen_defconfig

6. Bump the kernel version in the spec file
-------------------------------------------

# sed -ri "s/^(%define upstream_version).*$/\1 $(make kernelversion)/" packaging/*.spec
