[Xen-devel] [PATCH 1/8] debug: remove some event channel info from the 'i' and 'q' debug keys

[David Vrabel <david.vrabel@xxxxxxxxxx>]

From: David Vrabel <david.vrabel@xxxxxxxxxx>

With different event channel ABIs, showing the 2-level selector word
may be misleading (if a different ABI is in use).

When dumping domain information, printing the state of the VIRQ_DEBUG
port is redundant -- this information is available via the 'e' key.
