Hi,

This new version has changes suggested by Richard in patches 2 and 6.
Other patches are unchanged.

Series based on alistair/riscv-to-apply.next.

Patches missing review: 2, 3, 4, 5, 6.

Changes from v8:
- patch 2:
  - do an early exit if vstart >= vl in vext_ldst_stride(), vext_ldst_us()
    and vext_ldst_index() if vstart >= vl
- patch 6:
  - vec_set_vstart_zero() removed
  - set cpu_vstart directly using tcg_gen_movi_tl()
- v8 link: https://lore.kernel.org/qemu-riscv/20240308215402.117405-1-dbarboza@ventanamicro.com/
