Hi,

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.

Hi Mike,

I'd like to stress again that I'd prefer *any* secretmem allocations
going via CMA as long as these pages are unmovable. The user can
allocate a non-significant amount of unmovable allocations only fenced

lol, "non-neglectable" or "significant". Guess I need another coffee :)
