I believe he's talking about the SYSENTER/SYSEXIT instructions

And you can find /usr/src/linux/arch/i386/kernel/sysenter.c and
/usr/src/linux/arch/x86_64/kernel/syscall.c


Thanks, that's a big help - I wasn't sure what the new mechanism was called. Searching for syscall was almost futile on Google; sysenter is a much more useful keyword.
