    pci: fix handling of PCI bridges with subordinate bus number 0xff
    Bus number 0xff is valid according to the PCI spec. Using u8 typed sub_bus
    and assigning 0xff to it will result in the following loop getting stuck.
        for ( ; sec_bus <= sub_bus; sec_bus++ ) {...}
    Just change its type to unsigned int similarly to what is already done in

    x86/PVH: actually show Dom0's register state from debug key '0'
    vcpu_show_registers() didn't do anything for HVM so far. Note though
    that some extra hackery is needed for VMX - see the code comment.
    Note further that the show_guest_stack() invocation is left alone here:
    While strictly speaking guest_kernel_mode() should be predicated by a
    PV / !HVM check, show_guest_stack() itself will bail immediately for
    While there and despite not being PVH-specific, take the opportunity and
    filter offline vCPU-s: There's not really any register state associated
    with them, so avoid spamming the log with useless information while
    still leaving an indication of the fact.
