SECTION_SIZE is not defined for nommu systems. Trying to compile kexec in these conditions results in a build error: linux/arch/arm/kernel/setup.c: In function ‘reserve_crashkernel’: linux/arch/arm/kernel/setup.c:1016:25: error: ‘SECTION_SIZE’ undeclared (first use in this function); did you mean ‘SECTIONS_WIDTH’? crash_size, SECTION_SIZE); ^~~~~~~~~~~~ SECTIONS_WIDTH linux/arch/arm/kernel/setup.c:1016:25: note: each undeclared identifier is reported only once for each function it appears in linux/scripts/Makefile.build:265: recipe for target 'arch/arm/kernel/setup.o' failed Make KEXEC depend on MMU to fix the compilation issue.
