WARNING: CONFIG_AUDIT is invalid

Comment says: This will disable SELinux! That's ok, because hybris adaptations must not have SELinux, but if your device needs its support in kernel, set AUDIT=y and SELINUX_BOOTPARAM=y. Then disable them via kernel cmdline: audit=0 selinux=0. You can also leave audit enabled, if you don't plan to use systemd's containers: http://cgit.freedesktop.org/systemd/systemd/commit/README?id=77b6e19458f37cfde127ec6aa9494c0ac45ad890
