riscv: fence.i is not functional
Description of problem:
The attached user-level test is designed to do the following (in iteration):

  - Thread P0 on CPU0 changes some text/code, while

  - Thread P1 on CPU1 checks/reads the code, fence.i, then executes the same code.

Results (in stdout) indicates that CPU1 has read the new code (1:x5=a009) but executed the old one (1:x7=1) (against the specification).
Steps to reproduce:
1. echo 2 > /proc/sys/vm/nr_hugepages
2. ./CoRF+fence.i
Additional information:
Example output:
```[CoRF+fence.i.c](/uploads/c150ca0910783cc4bfc3886789b64c28/CoRF+fence.i.c)
