+        default y
+        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
+          disabling this option will generate a smaller kernel there. Hopefully
+          this algorithm is so good that allowing gcc4 to make the decision can
+          become the default in the future, until then this option is there to
+          test gcc for this.
