Subject: [PATCH V2 0/5] Add an optimization also raid6test for RISC-V support

The 1st patch is a cleanup;
Patch 2/4 is an optimization that takes Palmer's suggestion;
The last two patches add raid6test support and make the raid6 RVV code buildable on user space.

V2:
* Addressed comments from v1:
- Replaced one load with a move to speed up in _gen/xor_syndrome();
- Added a compiler error
- Dropped the NSIZE macro, instead of using the vector length;
- Modified has_vector() definition for user space;

Chunyan Zhang (5):
  raid6: riscv: Clean up unused header file inclusion
  raid6: riscv: replace one load with a move to speed up the caculation
  raid6: riscv: Add a compiler error
  raid6: riscv: Allow code to be compiled in userspace
  raid6: test: Add support for RISC-V
