The in-kernel x86 thing is going away (it's actually highly suboptimal).... Yes it's done in userland, this is the right place so far.... out of tree... well... there's no good place for such userspace tools in the kernel tree currently otherwise I'd love to have it there. If your distro doesn't install this by default, please file a bug against the distro; I know we (Intel) worked with Fedora, RHEL, SuSE and Ubuntu to get it included.... maybe others don't?
