Kill CONFIG_FEATURE_USE_DEVPS_PATCH and the devps patch. I'm not

maintaining it anymore, and it is now terribly out of date.

-I have been asked several times whether the devps patch will go into the
-mainline Linux kernel.  The following emails from Alan Cox and Linus Torvalds
-make it clear that it is not going to happen.  This does not mean this patch
-had no value -- it does.  It just means that those that like it get to apply it
-themselves...

-+ * human readable enough that mere mortals can actually look at the /proc
-+ * information and know what is happening on their computer (which is why we

-+ * This is bad, because:

-+ * 1) opening and closing lots of files is slow,
-+ *
-+ * 2) parsing lots of strings is slow,
-+ *
-+ * 3) every one of those strings had to be carefully printed out and formatted

-+ *
-+ * 4) using a virtual filesystem is not the traditional UN*X solution to
-+ * getting information from the kernel out to userspace (ioctls and syscalls
-+ * are the established way to do this), and worst of all
-+ *
-+ * 5) having a virtual filesystem around has been so inviting that everyone has
