This series adds Svinval extension support for both Host hypervisor
and Guest.

These patches can also be found in riscv_kvm_svinval_v1 branch at:
https://github.com/avpatel/linux.git

The corresponding KVMTOOL patches are available in riscv_svinval_v1
branch at: https://github.com/avpatel/kvmtool.git

Anup Patel (2):
  RISC-V: KVM: Use Svinval for local TLB maintenance when available
  RISC-V: KVM: Allow Guest use Svinval extension

Mayuresh Chitale (1):
  RISC-V: Probe Svinval extension form ISA string
