Subject[PATCH 0/2] xen/x86: use extended destination mode if available
Date
Hello,

Following two patches enable the usage of the extended destination ID if
supported by Xen. This is the same feature already supported by QEMU/KVM
and HyperV.

First patch can probably go in regardless of whether Xen ends up
implementing the extended destination ID, there's no reason to prevent a
VM from using x2APIC mode.

Thanks, Roger.
