Subject: [PATCH] x86: avoid confusion over the new RESCTRL config prompt

"Resource Control" is a very broad term for this CPU feature, and a
term that is also associated with containers, cgroups etc. This can
easily cause confusion.

Make the user prompt more specific.

As somebody who works in "resource control", this prompt in oldconfig
certainly had me go wtf. Can we do something more specific?

Not insisting on this name, and I haven't renamed all the config
symbols yet, but we should probably fix this before 5.0 is released.

Thanks!
