#     crypto: vmx - ghash: do nosimd fallback manually
#     
#     VMX ghash was using a fallback that did not support interleaving simd
#     and nosimd operations, leading to failures in the extended test suite.
#     
#     If I understood correctly, Eric's suggestion was to use the same
#     data format that the generic code uses, allowing us to call into it
#     with the same contexts. I wasn't able to get that to work - I think
#     there's a very different key structure and data layout being used.
#     
#     So instead steal the arm64 approach and perform the fallback
#     operations directly if required.
#     
#     Fixes: cc333cd68dfa ("crypto: vmx - Adding GHASH routines for VMX module")
