# HG changeset patch

# Node ID c191c649cdb387e7ec573d218c9581c639c87700
# Parent b3d901ba705d870c58ad327eff97fbdc5e21c063
Use explicitly-sized types in the dom0_ops and privcmd structures.
As discussed previously, the these operations are not performance-sensitive, so
the additional cache footprint shouldn't be an issue.
