MIPS Kconfig allows for excessively large ARCH_FORCE_MAX_ORDER. The patch changes nothing with regarards to this. But it changes meaning of ARCH_FORCE_MAX_ORDER and old configs are now breaks. Thomas, could you help with formulating more sensible upper limit for the config option, so it won't collide with SECTION_SIZE? -- Kiryl Shutsemau / Kirill A. Shutemov
