Otherwise the build fails because prom_init is calling symbols it's not allowed to, eg: Error: External symbol 'ftrace_likely_update' referenced from prom_init.c make[3]: *** [arch/powerpc/kernel/Makefile:197: arch/powerpc/kernel/prom_init_check] Error 1 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> --- arch/powerpc/kernel/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
