This is an implementation of "secret" mappings backed by a file descriptor. 
I've dropped the boot time reservation patch for now as it is not strictly
required for the basic usage and can be easily added later either with or
without CMA.

It seems early days for this, especially as regards reviewer buyin. 
But I'll toss it in there to get it some additional testing.

A test suite in tools/testging/selftests/ would be helpful, especially
for arch maintainers.

I'll look into it.

I assume that user-facing manpage alterations are planned?

Of course.
