Minimalistic Linux Kernel not compiling

I want to compile an own minimalistic Linux Kernel with make tinyconfig and after doing all steps (like here:)

I get this error message:

arch/x86/kernel/apic/apic.c:2282:6: error: redefinition of ‘apic_id_disabled’

#ifdef CONFIG_SMP
535 bool apic_id_is_primary_thread(unsigned int id);
536 bool apic_id_disabled(unsigned int id);
537 #else
538 static inline bool apic_id_is_primary_thread(unsigned int id) { return false; }
539 static inline bool apic_id_disabled(unsigned int id) { return false; }
540 #endif

actually you can see the conflict code in /arch/x86/include/asm/apic.h from these code, enable SMP in your config is the easiest way to fix this problem.

PROCESS:

 make menuconfig 
 -> Processor type and features

enable [Symmetric multi-processing support] there then

make -j8 # will compile successfully now
