pmbootstrap export
(cloned linux-next earlier)
(added device branch earlier)
(tried out envkernel.sh earlier, works fine)
(already added dts files to linux-next and commited)
(I didn't change the model and compatible strings
since the dts works anyways on the FrankenKernel)
(I want to see what happens with the current dts, not the minimal one)
(modified makefile earlier)

//while in Linux directory
source ../pmbootstrap/helpers/envkernel.sh
make qcom_defconfig
(I compiled the kernel earlier and I'm sadly impatient)
