With J.A.M.'s patch blessed by Andrew, #ifdef CONFIG_DEBUG_BUGVERBOSE goes around do_BUG() in fault.c, around its extern declaration in page.h, and around its export in i386_ksyms.c. Which stops compiling do_BUG() into an ndef CONFIG_DEBUG_BUGVERBOSE kernel. But I have an interest in compiling (some) modules once to run with different configurations of base kernel - and I'd expect the makers of Linux distributions to have a similar interest. Just how many versions of a driver do you need to build for your distribution? My main concern is to let modules be independent of HIGHMEM config: to which end I'd like one day (not imminent) to submit a patch in which even CONFIG_NOHIGHMEM kernel would have stubs for kmap_high() and kunmap_high(), to allow CONFIG_HIGHMEM modules to be linked in. Of course there's a limit to how far such a programme should go, but I don't think we should add CONFIG obstacles so cheaply avoided. I'd prefer a module built with CONFIG_DEBUG_BUGVERBOSE to link into a kernel built without CONFIG_DEBUG_BUGVERBOSE i.e. source as in -ac14, but the #ifdef CONFIG_DEBUG_BUGVERBOSE moved down one line in page.h. Am I a heretic?
