Thanks to whoever set this up :) so far VMA userland tests have not been
exercised very much and I've had to find issues manually :)

Hm this is strange, this works perfectly fine locally at this commit.

But it does seem this is duplicated so will fix-patch at this point in the series.

I notice the build is broken however at tip on next (will bisect), I guess the
bot hasn't got there yet? Seems somebody added a compiler directive that is not
stubbed out yet.

I might simply fix by adding to this commit as a stub to avoid hassle with
chasing down the offending patch...

Cheers, Lorenzo
