Re: [Xen-devel] IO-APIC: tweak debug key info formatting v2

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Respun to reduce the verbosity of names written out for each line. 
Contractions are:

vector -> vec
delivery_mode -> delivery
dest_mode -> dest
delivery_status -> status
trigger -> trig

In addition:
    vector is printed in hex
    dest and trig mode binary choices are represented with single
characters rather than full names
    delivery mode is converted from a number to a short string.

Output on one of my text boxes is as follows:
