Good idea, but according to the architecture supplement:
```
If SME is implemented, this does not imply that FEAT_SVE and FEAT_SVE2 are 
implemented by the PE when it is not in Streaming SVE mode.

I don't know how realistic such a core is but at a glance Linux doesn't say it 
wouldn't support it. I'll leave this as it is on that basis.
