There is an implicit padding of 2 bytes in struct xen_hvm_param between
the field domid and index. Make it explicit by introduce a padding
field. This can also serve as documentation.
Note that I don't think we can mandate it to be zero because a guest may
not have initialized the padding.
Agreed - we can mandate such only at introduction, not at any
later time.

Thank you!
(I doubt this is the only missing field to make padding explicit.)
Probably not, sadly. I stumbled accross the HVM param implicit padding
while looking at liveupdating the HVM param.
I guess I could use pahole to check the paddings are explicit for all
the public structure.
Cheers,
