Subject: [PATCH 0/1] RISC-V: kernel parameter for unaligned access speed

Add a kernel parameter to the unaligned access speed. This allows
skiping of the speed tests for unaligned accesses, which often is very
slow.

This patch requires (RISC-V: Detect and report speed of unaligned vector
accesses) to be applied first.
