+        help
+          This option determines if the kernel forces gcc to inline the functions
+          developers have marked 'inline'. Doing so takes away freedom from gcc to
+          do what it thinks is best, which is desirable for the gcc 3.x series of
+          compilers. The gcc 4.x series have a rewritten inlining algorithm and
+          enabling this option will generate a smaller kernel there. Hopefully
+          this algorithm is so good that allowing gcc 4.x and above to make the
+          decision will become the default in the future. Until then this option
+          is there to test gcc for this.
