[PATCH] ARM: Do not allow unaligned accesses when CONFIG_ALIGNMENT_TRAP

It is possible that -fconserve-stack is still valuable on ARM given that
it is also used with -mno-unaligned-access for other things than
structure packing on the stack, and therefore its merits can be debated
independently from the alignment issue at hand.

The big advantage of -fconserve-stack is that it throttles the inliner
if the inlining would cause too much stack growth. This is something
you likely want on ARM too, especially as code gets more and more
complex.

Is there no way to get that effect without also activating the
aggressive packing?
