-         Enabling this option will cause the kernel to distinguish between
-         ioremapped and physical addresses.  It will print a backtrace (at
-         most one every 10 seconds), hopefully allowing you to see which
-         drivers need work.  Fixing all these problems is a prerequisite
-         for turning on USE_HPPA_IOREMAP.  The warnings are harmless;
-         the kernel has enough information to fix the broken drivers
-         automatically, but we'd like to make it more efficient by not
-         having to do that.

+         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.
