This appears to fix the original issue of failing to boot from NFS when there are lots of alignment faults. But this is a very basic test relative to the reach of this change.
However the original patch has been in linux-next for a while and apparently nobody else noticed system calls randomly hanging on arm.
I assume maintainers need to give their opinion.
