      xen: Fix event channel callback via INTX/GSI
      
      [ Upstream commit 3499ba8198cad47b731792e5e56b9ec2a78a83a2 ]
      
      For a while, event channel notification via the PCI platform device
      has been broken, because we attempt to communicate with xenstore before
      we even have notifications working, with the xs_reset_watches() call
      in xs_init().
      
      We tend to get away with this on Xen versions below 4.0 because we avoid
      calling xs_reset_watches() anyway, because xenstore might not cope with
      reading a non-existent key. And newer Xen *does* have the vector
      callback support, so we rarely fall back to INTX/GSI delivery.
      
      To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
      startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
      case, deferring it to be called from xenbus_probe() in the XS_HVM case
      instead.
      
      Then fix up the invocation of xenbus_probe() to happen either from its
      device_initcall if the callback is available early enough, or when the
      callback is finally set up. This means that the hack of calling
      xenbus_probe() from a workqueue after the first interrupt, or directly
      from the PCI platform device setup, is no longer needed.

      xen: Fix event channel callback via INTX/GSI
      
      [ Upstream commit 3499ba8198cad47b731792e5e56b9ec2a78a83a2 ]
      
      For a while, event channel notification via the PCI platform device
      has been broken, because we attempt to communicate with xenstore before
      we even have notifications working, with the xs_reset_watches() call
      in xs_init().
      
      We tend to get away with this on Xen versions below 4.0 because we avoid
      calling xs_reset_watches() anyway, because xenstore might not cope with
      reading a non-existent key. And newer Xen *does* have the vector
      callback support, so we rarely fall back to INTX/GSI delivery.
      
      To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
      startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
      case, deferring it to be called from xenbus_probe() in the XS_HVM case
      instead.
      
      Then fix up the invocation of xenbus_probe() to happen either from its
      device_initcall if the callback is available early enough, or when the
      callback is finally set up. This means that the hack of calling
      xenbus_probe() from a workqueue after the first interrupt, or directly
      from the PCI platform device setup, is no longer needed.
