I tried giving this a whirl.

Maybe the order of my layers in bblayers isn't correct, but by default my
build uses 4.4% instead of 4.8%.

conf/machine/raspberrypi3-64.conf includes:
	...
	include conf/machine/include/rpi-base.inc
	...
	PREFERRED_VERSION_linux-raspberrypi ?= "4.8.%"

conf/machine/include/rpi-base.inc contains:
	...
	include conf/machine/include/rpi-default-versions.inc
	...

conf/machine/include/rpi-default-versions.inc contains:
	...
	PREFERRED_VERSION_linux-raspberrypi ?= "4.4.%"

In any case when I try building with 4.4 I get:

	ERROR: linux-raspberrypi-1_4.4.28+gitAUTOINC+5afda48c34-r0 do_kernel_configme: No default configuration for raspberrypi3-64 / bcmrpi3_defconfig available.
	ERROR: linux-raspberrypi-1_4.4.28+gitAUTOINC+5afda48c34-r0 do_kernel_configme: Function failed: do_kernel_configme (log file is located at /z/layerindex-master/raspi3-64/tmp-glibc/work/raspberrypi3_64-oe-linux/linux-raspberrypi/1_4.4.28+gitAUTOINC+5afda48c34-r0/temp/log.do_kernel_configme.15498)

When I switch to 4.8 explicitly in my conf/local.conf I get:

	ERROR: linux-raspberrypi-1_4.8.8+gitAUTOINC+ea6eeaff07-r0 do_fetch: Fetcher failure: Unable to find revision ea6eeaff07c4881e6287fe3e7ea58fc30e5569d7 in branch rpi-4.8.y even from upstream
