--- Comment #1 from Ed Maste <[email protected]> ---
Interesting, old POSIX required EINVAL for unaligned addr but Issue 7 changed
it to may fail with EINVAL -- "Austin Group Interpretation 1003.1-2001 #078 is
applied, clarifying page alignment requirements."

In any case, regardless of what the native ABI does the Linuxulator needs to
follow Linux behaviour.
