Unfortunately that would be the 21st aux table entry on powerpc, meaning that the aux table including the terminating null entry would overflow the mm->saved_auxv[] array, leading to userland programs segfaulting. This increases the size of the mm->saved_auxv array to be large enough to accommodate an AT_PLATFORM entry on powerpc.
