Anyway, let me think about this, but just for testing, does the
attached patch make any difference? It's not the right thing in
general (and most definitely not on x86), but for testing whether this
is about unaligned accesses it might work.
All my alpha, sparc64, and xtensa tests pass with the attached patch
applied on top of v5.4-rc2. I didn't test any others.
I'll (try to) send you some disassembly next.
