Please cc the guilty parties when sending patches like this.
Also, just out of interest, please describe how this bug affected
things. Did we overflow the saved_auxv[] array, or what? Also, how
does this change affect architectures that _don't_ have that
ELF_HWCAP2 thing, ie everything but powerpc?
Acks, people?
