This was valid, since ppc_save_regs was called only in replay_system_reset() of old irq.c which was under BOOK3S. But there has been multiple refactoring of irq.c and have added call to ppc_save_regs() from __replay_soft_interrupts -> replay_soft_interrupts which is part of irq_64.c included under CONFIG_PPC64. And since ppc_save_regs is called in CRASH_DUMP path as part of crash_setup_regs in kexec.h, CONFIG_PPC32 also needs it. So with this recent patch which enabled the building of ppc_save_regs.c caused a build break when none of these (XMON, KEXEC_CORE, BOOK3S) where enabled as part of config. Patch to enable building of ppc_save_regs.c by defaults.
