On 64 bit architectures with no efficient unaligned access, taskstats
has to add some padding to a reply to prevent unaligned access warnings.
However this also needs to apply to 32 bit architectures with 64 bit
struct alignment such as metag (which has 64 bit memory accesses).
Wait... 64-bit struct alignment on structures with only 32-bit members?
That might be... interesting... in a number of places...
