What does it mean? --- Quote End --- Maybe, you have the file '/arch/nios2/hernel/cpuinfo.c'. http://lxr.free-electrons.com/source/arch/nios2/kernel/cpuinfo.c

.......
75 if (IS_ENABLED(CONFIG_NIOS2_HW_MUL_SUPPORT) && !cpuinfo.has_mul)

Did you setup 'CONFIG_NIOS2_HW_MUL_SUPPORT'? And also please check the contents of your dst file. Kazu
