Note that it's not simply unused code. There have been quite a few changes to the ptrace interface over the last year, including moving more code into generic helpers. Take a look at those architectures defining HAVE_ARCH_TRACEHOOK in their Kconfig for a guide. Fortunately it should make the remaining architecture code a lot simpler. Also http://sourceware.org/systemtap/wiki/utrace/arch/HowTo might be pretty helpful.
