    SubjectRe: [RFC PATCH v2 20/69] KVM: x86/mmu: Mark VM as bugged if page fault returns RET_PF_INVALID

    For a changelog:

    Mark a VM as bugged instead of simply warning if the core page fault
    handler unexpectedly returns RET_PF_INVALID. KVM's (undocumented) API
    for the page fault path does not allow returning RET_PF_INVALID, e.g. a
    fatal condition should be morphed to -errno.
