From: "Luis R. Rodriguez" <mcg...@suse.com>
This lets you build a kernel which can support xen dom0
or xen guests by just using:
make xenconfig
on both x86 and arm64 kernels. This also splits out the
options which are available currently to be built with x86
and 'make ARCH=arm64' under a shared config.
Technically xen supports a dom0 kernel and also a guest
kernel configuration but upon review with the xen team
since we don't have many dom0 options its best to just
combine these two into one.
