Trinity will at least need an addition to include/compat.h for
older headers that won't have the definition.  Looks ok otherwise.

Also, I usually sit on stuff like this until the syscall numbers are
in Linus tree. This is 3.19 stuff I presume ?
istr akpm picked up execveat recently, so if that goes in first, we'll
need to respin this anyway..
