Once you have downloaded the backports, installed required headers (for the UEK4 kernel!) then reboot into the UEK4 kernel and run the backports-4.4.2-1]# make defconfig-iwlwifi IMPORTANT NOTE: The following steps have to be done when you are booted into the UEK4 kernel! You have to download all the stuff you need when you are booted into the Oracle RedHat Compatible Kernel (which comes with the Oracle Linux distribution) because wired and wireless networking both work out of the box on that kernel on the Lenovo P70 mobile workstation. The good news is that I refined this procedure a bit and of course finally noticed that you only need to run "defconfig-iwlwifi" not the entire "defconfig-wifi" which is much quicker 2 or 3 minute operation to restore onboot wireless support for UEK4. Fortunately the backport can be applied again. And yup it broke Intel 8260 wireless support for the Lenovo P70 Mobile Workstation. Being a serial fearless update-applier I boldly forged ahead.
