Commit 5d971f9e67 ("memory: Revert "memory: accept mismatching sizes in memory_region_access_valid"") was cherry-picked to deal with CVE-2020-13754 but the follow up fix in commit ab3d207fe8 ("riscv: sifive_test: Allow 16-bit writes to memory region") was not, resulting in the bug described in the commit message in 1:4.2-3ubuntu6.11: https://github.com/nathanchance/continuous-integration2/runs/1834110909

Please consider adding ab3d207fe8 to the next release so that there is no more regression.
