manually? I am using linux-libre core, cause it is free. I cannot remove
everything non-free. So what exactly I need?
How to compile 4.13? Can I not to use current config? So will I need setup
kernel options or there are default options that will work?
... I downloaded linux-source-4.4.0 and started `make menuconfig && make` . I
did not use my current config. Just rested things as it was and also disabled
bluetooth and irda. Now it is making 15 minutes. (Making of 4.13 stopped
after 4 minutes).
I think config for 4.4 cannot work for 4.13.
Why there is no anywhere info about how to get config for upstream version ?
I thought kernel has no any configurations set and I tried to use my current
config.
