+       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.
