Looks like a nice resource, note the links to the x86-64 ABI docs at
http://www.x86-64.org/documentation.html - these are worth reading.

Under Linux, you should find these via /usr/include/sys/syscall.h.
Note that you may need to follow a couple of #include redirections
from there. For example, on my Ubuntu 8.10 Intrepid install the actual
list of 64bit syscalls is in /usr/include/asm/unistd_64.h, which ends
up getting included (via a somewhat circuitous route) into
sys/syscall.h.

I think this would be (increasingly) useful.
