[Anup Patel]

Hi Paolo,

We have the following KVM RISC-V changes for 6.6:
1) Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for Guest/VM
2) Added ONE_REG interface for SATP mode
3) Added ONE_REG interface to enable/disable multiple ISA extensions
4) Improved error codes returned by ONE_REG interfaces
5) Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
6) Added get-reg-list selftest for KVM RISC-V

Please pull.

Regards,
Anup
