both are written in jen-you-wine C++. no use to the kernel. however,
the folks from GRAME recently posted a summary/short paper on their
stuff, which I'll forward to you separately.

Nope, unless you want to exclude "historical" Intel platforms. There
may be other "current" architectures that don't include it either.
