This PR removes the constant defining the max attachment address and replaces it with the largest address that shows up in /proc/self/maps. This should address issues found on AARCH64 where the max address may differ based on the configuration. Since the calculated max address may differ between processes the max address is sent as part of the modex and stored in the endpoint data. Signed-off-by: Nathan Hjelm <hjelmn@google.com>
