This series adds Sstc extension which was ratified recently.

The first two patches adds the ISA extension framework which allows
to define and update the DT for any multi-letter ISA extensions. 

The last patch just enables Sstc extension specifically if the hardware
supports it.

The series can also be found at
https://github.com/atishp04/kvmtool/tree/sstc_v1

The kvm & Qemu patches can be found at

KVM: https://github.com/atishp04/linux/tree/sstc_v2
OpenSBI: https://github.com/atishp04/opensbi/tree/sstc_v1
Qemu: https://github.com/atishp04/qemu/tree/sstc_v1

These look fine to me. What's the status of the kernel-side changes?

The kernel-side of changes will be merged for 5.19 or 5.20.

I will ping you once kernel-side changes are merged.

Thanks,

I will revise the kernel series soon and rebase the kvmtool changes on
the latest.
