    KVM: x86: Allow marking an exception as reinjected · ce7ddec4
    Joerg Roedel 提交于
    This patch adds logic to kvm/x86 which allows to mark an
    injected exception as reinjected. This allows to remove an
    ugly hack from svm_complete_interrupts that prevented
    exceptions from being reinjected at all in the nested case.
    The hack was necessary because an reinjected exception into
    the nested guest could cause a nested vmexit emulation. But
    reinjected exceptions must not intercept. The downside of
    the hack is that a exception that in injected could get
    lost.
    This patch fixes the problem and puts the code for it into
    generic x86 files because. Nested-VMX will likely have the
    same problem and could reuse the code.
