Hi,

This version has changes in the document patch, as suggested by Andrew
in v2. It also has a new patch (patch 9) that handles error code changes
in vcpu_vector.c.

Patches rebased on top of kvm_riscv_queue.

Changes from v2:
- patch 9 (new):
  - change kvm error codes for vector registers
- patch 10 (former 9):
  - rewrite EBUSY doc to mention that the error code indicates that it
    is not allowed to change the reg val after the vcpu started.
- v2 link: https://lore.kernel.org/kvm/20230801222629.210929-1-dbarboza@ventanamicro.com/

  RISC-V: KVM: return ENOENT in *_one_reg() when reg is unknown
  RISC-V: KVM: use ENOENT in *_one_reg() when extension is unavailable
  RISC-V: KVM: do not EOPNOTSUPP in set_one_reg() zicbo(m|z)
  RISC-V: KVM: do not EOPNOTSUPP in set KVM_REG_RISCV_TIMER_REG
  RISC-V: KVM: use EBUSY when !vcpu->arch.ran_atleast_once
  RISC-V: KVM: avoid EBUSY when writing same ISA val
  RISC-V: KVM: avoid EBUSY when writing the same machine ID val
  RISC-V: KVM: avoid EBUSY when writing the same isa_ext val
