[Qemu-devel] [PULL 06/21] xen: use 5 digit xen versions

[Stefano Stabellini]

From: Juergen Gross <address@hidden>

Today qemu is using e.g. the value 480 for Xen version 4.8.0. As some
Xen version tests are using ">" relations this scheme will lead to
problems when Xen version 4.10.0 is being reached.

Instead of the 3 digit schem use a 5 digit scheme (e.g. 40800 for
version 4.8.0).
