The patches added here are required to build under some conditions, but not all are ended up needed as CONFIG_DEBUG_FS is required to be active otherwise the kernel doesn't even boot :/ The kernel size was reduced by: * Removing tracing support * Removing unneeded exfat and sdcardfs filesystems * Removing all sound support * Removing video input (camera) support The latter options seem awfully shortsighted, until you remember that a goal is to eventually deal with booting our own kernels through kexec. The Moto Z Play device's boot partition size is putting us in a hard spot.
