Looks ok to me. Starting off with a compile-time config option seems fine.
I do think that the x86 cpuid part should (patch 15) should be the
first patch, so that we see "la57" as a capability in /proc/cpuinfo
whether it's being enabled or not? We should merge that part
regardless of any mm patches, I think.
