Does this mean you're able to run sun4v? When I checked the other week it was broken by the interrupt filter changes back in February.

Ah, no, that means I made a typo; for sun4v it's compile-tested only :)

OK, probably a followup commit would be good. Inaccurate comments in commit logs have a way of confusing people when they look at them years later.

Speaking of sun4v -- it sounds like sun4v support in 7.0 is at risk. I think I understand from a comment I saw from Kip that there are (at least) two issues:

(1) An issue in VM handling that will be resolved by alc's replacement
    contigmalloc.  I don't know what the details are here.

(2) An issue involving sun4v breakage post-ifilters.  No details here either.

If we're going to ship a 7.0 release for sun4v, we need to get these things resolved. Do we have a sense of what work is required here?
