As result, the following build error may now be seen if CONFIG_PPC_SPLPAR=y and CONFIG_DTL=n. arch/powerpc/kernel/irq.o: in function `.do_IRQ': irq.c:(.text+0x2798): undefined reference to `.pseries_accumulate_stolen_time' I updated my own configurations to avoid the problem, but you might see randconfig failures with this error in the future.
