[Xen-devel] [PATCH] xen: update_runstate_area for 32 bit PV on HVM guests

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
the current implementation of update_runstate_area is unable to handle
32 bit PV on HVM guests because the check is_pv_32on64_domain doesn't
cover that case. This patch fixes it.
