Currently we set the length of PPC_BREAKPOINT_MODE_EXACT breakpoints to 8. This is wrong as in exact mode we should only match on 1 address, hence the length should be 1. This ensures that the kernel will filter out any exact mode hardware breakpoint matches on any addresses other than the requested one.
