(Get the code!)
The SVE linux kernel issue is present in kernels < 6.3. "When encountering the next SVE instruction in user space, an exception (trap) is triggered that then re-enables SVE and restores the SVE context. This causes a 6% or worse performance degradation on our NGNIX test workload in a single core system.
With this we should hold off on merging SVE memcpy/memmove."
