Memory Protection Keys for User pages is a CPU feature which will
first appear on Skylake Servers, but will also be supported on
future non-server parts.  It provides a mechanism for enforcing
page-based protections, but without requiring modification of the
page tables when an application changes protection domains.  See
the Documentation/ patch for more details.

What, if anything, happened to the signal handling parts?

Also, do you have a git tree for this somewhere?  I can't actually
enable it (my laptop, while very shiny, is not a Skylake server), but
I can poke around a bit.
