Hi,

thanks for taking a shot at the eBPF JIT; this will be very useful.

From a hardware point of view, this is not the case on the Linux-capable 
RISC-V ASICs that the public can buy right now (to the best of my 
knowledge this is only the SiFive FU540).

So I'd recommend not including this for now.
