Hi,

In this version we're exporting all vector regs, not just vector CSRs,
in get-reg-list. All changes were done in patch 3.

No other changes made.

Changes from v2:
- patch 3:
  - check num_vector_regs() != 0 before copying vector regs
  - export all 32 vector regs in num_vector_regs() and copy_vector_reg_indices()
  - initialize 'size' out of the loop in copy_vector_reg_indices()
- v2 link: https://lore.kernel.org/kvm/20231205135041.2208004-1-dbarboza@ventanamicro.com/

Daniel Henrique Barboza (3):
  RISC-V: KVM: set 'vlenb' in kvm_riscv_vcpu_alloc_vector_context()
  RISC-V: KVM: add 'vlenb' Vector CSR
  RISC-V: KVM: add vector CSRs in KVM_GET_REG_LIST
