Log message:
Add kernel support for the vector extension on riscv64.
The V extension (where supported) adds an additional 32 vector registers
that are variable length (up to 65,536 bits, but more commonly 2048 bits).
In order to support the use of the V extension (and additional vector
extensions) we need to enable the vector extension and save/restore the
vector registers.
