Don't be surprised if we see more separation like this in the future too.
Yes, with the whole meltdown fiasco, there's actually more pressure to add more support for separation of kernel/user address spaces. As Andy pointed out, it's been discussed as a future wish-list for x86-64 too.
S/390 is another example.
I've also proposed a RISC-V extension for it, including prototypes for Rocketchip and Qemu, and a Linux kernel support, but it didn't go any way.
