openSUSE 13.2 custom kernel guide

Here is the way of mine which results in a working kernel (and i suggest
to take 3.17.6 or 3.17.7). I use only the sources from kernel.org and
the BFQ scheduler patches.

# make mrproper
# patch WhatYoutWantToHave.patch(es)
# make distclean
# zcat /proc/config.gz > .config

Comment: For the first step to a new kernel release i even download the
kernel source from the suse kernel repo to take a look at the
kernel-desktop config file during the first "make oldconfig". You can
use this newer kernel config as ".config" too.

Attention: In the first step to another kernel than the one from suse i
deactivate a lot of CONFIG_DEBUG* to get a "normal" size for the
kernel and the modules. I think this is because suse split the
debug-files in another package.

# make oldconfig 2>&1 | tee ../make_oldconfig-$(date --iso-8601).log
# make menuconfig => Change CONFIG_LOCALVERSION (example -1-new)
# make modules_prepare
# make -j4 2>&1 | tee ../make_kernel-$(date --iso-8601).log
# make kernelrelease (CHECK Kernel Release Name)

Comment: From here on i run the rest as root.

# make INSTALL_FW_PATH=/lib/firmware/3.17.7-1-new modules_install
# cp arch/x86/boot/bzImage /boot/vmlinuz-3.17.7-1-new
# cp System.map /boot/System.map-3.17.7-1-new
# cp .config /boot/config-3.17.7-1-new
# cd /boot
# mkinitrd -k vmlinuz-3.17.7-1-new -i initrd-3.17.7-1-new
# grub2-mkconfig --output=/boot/grub2/grub.cfg
