Patch from Nicolas Pitre struct statfs64 has extra padding with EABI growing its size from 84 to 88. This struct is now __attribute__((packed,aligned(4))) with a small assembly wrapper to force the sz argument to 84 if it is 88 to avoid copying the extra padding over user space memory unexpecting it.
