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...

Hi,

I'll rewrite the description as it's a bit misleading. On metag 64bit
struct alignment is required when it contains 64bit members, not if it
only contains 32bit members. Although metag is a 32bit arch, it can do
64bit memory accesses which must be aligned.

Thanks for taking a look.
