this fix is far from ideal and breaks the rule of not using arch-specific #ifdefs, but for now we just need a solution to the existing breakage. the underlying problem is that the kernel folks made a very stupid decision to make misalignment of this struct part of the kernel API/ABI for x86_64, in order to avoid writing a few extra lines of code to handle both 32- and 64-bit userspace on 64-bit kernels. I had just added the packed attribute unconditionally thinking it was harmless on 32-bit archs, but non-x86 32-bit archs have 8-byte alignment on 64-bit types.
