Can I add these symbols to the async_wake_ios project?

Rikifire - be my guest! Just fixed an issue with the KSYMBOL_WRITE_SYSCALL_ENTRYPOINT so you should be good to go.

Thank you so much! I'm trying to extract the symbols of iPhone 6, but I'm stuck after CPU_DATA_ENTRIES.

Cool - the iphone 6 symbols are actually the same as ipod6g that's already in there - check out my coworker's repo :)
