# Compile the kernel that we're going to run and be emulating with. This is
# basically just done to be compatible with the QEMU target that we're going
# to be using when running tests. If any other kernel works or if any
# other QEMU target works with some other stock kernel, we can use that too!
#
# The `vexpress_config` config file was a previously generated config file for
# the kernel. This file was generated by running `make vexpress_defconfig`
# followed by `make menuconfig` and then enabling the IPv6 protocol page.
