Hi Paolo,

We have following KVM RISC-V changes for 5.19:
1) Added Sv57x4 support for G-stage page table
2) Added range based local HFENCE functions
3) Added remote HFENCE functions based on VCPU requests
4) Added ISA extension registers in ONE_REG interface
5) Updated KVM RISC-V maintainers entry to cover selftests support

I don't expect any other KVM RISC-V changes for 5.19.

Please pull.

Regards,
Anup
