Subject[PATCH 2/4] powerpc: Panic on platform ppc-xicp when CONFIG_XICS not set instead of build failure
Date
If CONFIG_XICS is not set but CONFIG_PPC_PSERIES is, then the kernel
fails to build with

arch/powerpc/platforms/pseries/smp.c: In function ‘smp_init_pseries_xics’:
arch/powerpc/platforms/pseries/smp.c:202: error: ‘pSeries_xics_smp_ops’ undeclared (first use in this function)
arch/powerpc/platforms/pseries/smp.c:202: error: (Each undeclared identifier is reported only once
arch/powerpc/platforms/pseries/smp.c:202: error: for each function it appears in.)
make[2]: *** [arch/powerpc/platforms/pseries/smp.o] Error 1

As CONFIG_XICS is not always necessary, this patch allows the kernel to
build but the system will panic at runtime if it is found that XICS is
required.
