It looks like it:
$ make arch/x86/kernel/cpu/mcheck/mce_amd.i
$ grep 'asm/smp.h' arch/x86/kernel/cpu/mcheck/mce_amd.i
# 1 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h" 1
# 13 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h"
# 14 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h" 2
# 16 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h" 2
and this one pulls in the cpu_llc* crap.
# 183 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h"
# 225 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h"
# 236 "/home/boris/kernel/linux-2.6/arch/x86/include/asm/smp.h"
So some other headers seem to pull in asm/smp.h.
HTH.
