Make sys_recv a first class citizen by using the SYSCALL_DEFINEx
macro. Besides being cleaner this will also generate meta data
for the system call so tracing tools like ftrace or LTTng can
resolve this system call.

Networking patches should be sent to netdev@vger.kernel.org so that they
are properly queued up in patchwork.
Thank you.
