This series implements support for allowing KVM guests to use the Arm
Scalable Vector Extension (SVE), superseding the previous v5 series [1].

The patches are also available on a branch for reviewer convenience. [2]

The patches are based on v5.1-rc1.

The series has been reworked to remove the dependency on [3],
eliminating the ABI "fixes" but keeping the relevant cleanup/
refactoring.  (See patch 16.)

This series addresses review comments received on v5, and contains one
significant change:

 * A new ioctl KVM_ARM_VCPU_FINALIZE is added to replace the implicit
   finalization behaviour in v5.  If userspace enables SVE, it must now
   use this ioctl to finalize the vcpu configuration before KVM_RUN
   etc. or SVE register access are permitted.

For a description of minor updates, see the individual patches.


Known issues:

 * This update requires modifications to kvmtool that are not published
   yet.  I will reply to this cover letter with a link when those are
   available (hopefully within 24 hours of this posting).

Hi Dave and Peter,

Do either of you know if anyone has picked up the QEMU side of this?
If not, then I'll take it.

Thanks,
drew
