    Subject[PATCH 16/47] KVM: SVM: complete interrupts after handling nested exits
    Date
    From: Joerg Roedel <joerg.roedel@amd.com>

    The interrupt completion code must run after nested exits are handled
    because not injected interrupts or exceptions may be handled by the l1
    guest first.
