Fix ia64 build setup_per_cpu_areas() redifinition issue in UP
configuration. When compiling ia64 kernel in UP configuration, the
following compilation errors are reported:
arch/ia64/kernel/setup.c:860: error: redefinition of 'setup_per_cpu_areas'
include/linux/percpu.h:185: error: previous definition of 'setup_per_cpu_areas' was here
