riscv patches for 6.16-rc1, part 2

* Performance improvements
  - Add support for vdso getrandom
  - Implement raid6 calculations using vectors
  - Introduce svinval tlb invalidation

* Cleanup
  - A bunch of deduplication of the macros we use for manipulating instructions

* Misc
  - Introduce a kunit test for kprobes
  - Add support for mseal as riscv fits the requirements (thanks to Lorenzo for making sure of that :))

[Palmer: There was a rebase between part 1 and part 2, so I've had to do
some more git surgery here... at least two rounds of surgery...]
