    tools/hotplug/Linux: Use correct device name for vifs in setup scripts
    
    In vif-common.sh, set the shell variable "dev" to the new interface
    name when interfaces are renamed, and consistently use this variable
    in all the vif scripts.
    
    This fixes hotplug of renamed interfaces.

    libxl/xl: improve behaviour when guest fails to suspend itself.
    
    The PV suspend protocol requires guest co-operating whereby the guest
    must respond to a suspend request written to the xenstore control node
    by clearing the node and then making a suspend hypercall.
    
    Currently when a guest fails to do this libxl times out and returns
    a generic failure code to the caller.
    
    In response to this failure xl attempts to resume the guest. However
    if the guest has not responded to the suspend request then the is no
    guarantee that the guest has made the suspend hypercall (in fact it is
    quite unlikely). Since the resume process attempts to modify the
    return value of the hypercall (to indicate a cancelled suspend) this
    results in the guest eax/rax register being corrupted!
    
    To fix this change libxl to do the following:
       * Wait for the guest to acknowledge the suspend request.
         - on timeout cancel the suspend request.
           - if cancellation is successful then return a new error code to
             indicate that the guest is not responding.
           - if the cancel does not succeed then we raced with the guest
             which actually did acknowledge at the last minute, so
             continue.
       * Wait for the guest to suspend.
         - on timeout return the standard error code as before
       * Guest successfully suspended, return success.
    
    Lastly in xl do not attempt to resume a guest if it has not responded
    to the suspend request.
    
    Tested by live migration of PVops kernels which either ignore the
    suspend request, have already crashed and those which suspend/resume
    correctly. In the first two cases the source domain is left alone (and
    continues to function in the first case) and in the third the
    migration is successful.

    libxl: allow guest to write "control/shutdown" xenstore node.
    
    The PV shutdown/reboot/suspend protocol requires that the guest
    acknowledge a request by clearing the node therefore it is necessary
    to allow the guest to write to the node.
    
    Currently libxl is quite relaxed about this protocol and doesn't
    reeally seem to mind that the guest is unable to write the node to
    perform the acknowledgement. However in a followup patch libxl needs
    to be able to detect that a guest has acknowledged a suspend request.
    
    A side effect of this change is that an empty "control/shutdown" node
    is created upon domain creation instead of only being created when a
    shutdown/reboot/suspend is requested. This should not (and does not
    in my tests) have any negative impact on the guest.

    libxc: increase lzma max memory constant to 128Mby
    
    According to lzma's configure.ac (!) the minimum memory limit to cope
    with arbitrary input is 128Mby (!)
    
    This is obviously an unreasonable amount of memory for this kind of
    task, but we need to increase the constant limit for it not to
    randomly fail.  So do so.
