[Qemu-devel] [PATCH 00/20] target/arm: sve system mode patches

[Richard Henderson]

This is my current set of patches for running SVE in system mode.

The first half deal with the system registers that affect SVE.
I recall that Peter has said he'd like the first patch to be
done a different way, but we haven't had a chance to talk about
what form it should take.  I've left it as-is since it does what
I need for now.

The second half re-implement the SVE memory operations.
The FF and NF loads had been stubbed out.  Getting those to work
requires some infrastructure that can be reused to speed up normal
loads -- one guest-to-host tlb lookup can be reused for the rest
of the page.
