    KVM: MMU: fix permission_fault() · 7a98205d

    kvm-unit-tests complained about the PFEC is not set properly, e.g,:
    test pte.rw pte.d pte.nx pde.p pde.rw pde.pse user fetch: FAIL: error code 15
    expected 5
    Dump mapping: address: 0x123400000000
    ------L4: 3e95007
    ------L3: 3e96007
    ------L2: 2000083
    It's caused by the reason that PFEC returned to guest is copied from the
    PFEC triggered by shadow page table
    This patch fixes it and makes the logic of updating errcode more clean
