-	This tells the system call number for new_s_context and set_ipv4root
-	using /proc/self/status. This helps until the vserver project is
-	included officially in the kernel (and has its own syscall).
-
-	We rely on /proc/self/status to find the syscall number.
-
-	If it is not there, we rely on adm/unistd.h.
-
-	If this file does not have those system calls (not a patched kernel source)
-	we rely on static values in this file.
