[Xen-devel] [PATCH] Avoid endless loop for vcpu migration

[Juergen Gross <juergen.gross@xxxxxxxxxxxxxx>]

On multi-thread multi-core systems an endless loop can occur in vcpu_migrate()
with credit scheduler. Avoid this loop by changing the interface of pick_cpu
to indicate a repeated call in this case.
