This series extends the KVM RISC-V ONE_REG interface to report few more
ISA extensions namely: Ztso and Zacas. These extensions are already
supported by the HWPROBE interface in Linux-6.8 kernel.

To test these patches, use KVMTOOL from the riscv_more_exts_round2_v1
branch at: https://github.com/avpatel/kvmtool.git

These patches can also be found in the riscv_kvm_more_exts_round2_v1
branch at: https://github.com/avpatel/linux.git

Anup Patel (5):
  RISC-V: KVM: Forward SEED CSR access to user space
  RISC-V: KVM: Allow Ztso extension for Guest/VM
  KVM: riscv: selftests: Add Ztso extension to get-reg-list test
  RISC-V: KVM: Allow Zacas extension for Guest/VM
  KVM: riscv: selftests: Add Zacas extension to get-reg-list test
