[PATCH 2/2] powerpc/powernv : Disable subcore for UP configs

[Shreyas B. Prabhu]

Build throws following errors when CONFIG_SMP=n
arch/powerpc/platforms/powernv/subcore.c: In function âcpu_update_split_modeâ:
arch/powerpc/platforms/powernv/subcore.c:274:15: error: âsetup_max_cpusâ undeclared (first use in this function)
arch/powerpc/platforms/powernv/subcore.c:285:5: error: lvalue required as left operand of assignment

'setup_max_cpus' variable is relevant only on SMP, so there is no point
working around it for UP. Furthermore, subcore.c itself is relevant only
on SMP and hence the better solution is to exclude subcore.c for UP builds.
