ARM: 8456/1: code patching only works on MMU
There is no __set_fixmap implementation for NOMMU kernels, so we cannot link the kernel/patch.c file: arch/arm/kernel/built-in.o: In function `patch_map': :(.text+0x257e): undefined reference to `__set_fixmap' arch/arm/kernel/built-in.o: In function `__patch_text_real': :(.text+0x2618): undefined reference to `__set_fixmap' :(.text+0x262e): undefined reference to `__set_fixmap' To work around that, this adds dependencies for all features that rely on code patching.
