Yes, the concept is not a new one in hardware. At least x86, s390, powerpc and ia64 have some form of protection keys. x86 was the outlier for *not* having it.
However, there is currently no general support for these features on any of these architectures in Linux. These patches are the first proposal I know of to use this hardware in Linux in any substantive way.
