Subject: [PATCH 1007/1018] libxl: allow kernel cmdline without kernel if
 stubdomain is used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Qubes's stubdomain gets the kernel (and initramfs) on a block device for
direct kernel boot. Allow using standard method of passing kernel
cmdline in this case too.
