[PATCH] Increase AT_VECTOR_SIZE
On PowerPC, we want to be able to provide an AT_PLATFORM aux table entry to userspace, so that glibc can choose optimized libraries for the processor we're running on. 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.
