	####### Rebase config
	# The kernel config needs to be periodically rebased to enable new
	# modules/features that Purism has enabled in their defconfig. This is done
	# by: 1) generate .config using librem5_defconfig, 2) diff that .config
	# with the config in this package, 3) carefully going over the diff and
	# selecting new things enabled in their config.
	#
	# This can be uncommented to help generate the defconfig using "pmbootstrap
	# build linux-purism-librem5". The build will fail (exit 1) to let you grab
	# the config before it starts building the kernel:
	#    make ARCH="$_carch" CC="${CC:-gcc}" \
	#       defconfig KBUILD_DEFCONFIG=librem5_defconfig
	#    exit 1
