This series adds basic support for the vector crypto extensions:
* Zvkb
* Zvkg
* Zvkh[a,b]
* Zvkn
* Zvksed
* Zvksh
The implementation follows the version 20221220 of the specification,
which can be found here:
https://github.com/riscv/riscv-crypto/releases/tag/v20221220
Note, that this specification is not frozen yet, meaning that
incompatible changes are possible.
Therefore, this patchset is marked as RFC and should not be considered
for upstream inclusion.
All extensions come with (passing) tests for the feature test macros.
A Binutils patch series for vector crypto support can be found here:

I don't see anything objectionable in here. I'd guess that most (but
perhaps not all) of these will wire up as builtins at some point in the
not too distant future.
