Logging a messages sounds like a good idea. Ignoring the users
request
of iova-mode=PA (in the case of x86) and just switching modes would be
bad.
Yes, I mean for ppc64, if --no-huge is specified,
would you like to change the default to VA mode?
OK, that would be better.
I will switch to VA when --no-huge is set (ppc64 only).
Add log messages if PA is selected with --no-huge (all arches).
