+Subject: powerpc/kernel: Fix ppc_save_regs inclusion in build
+
+From: Madhavan Srinivasan <maddy@linux.ibm.com>
+
+commit 93bd4a80efeb521314485a06d8c21157240497bb upstream.
+
+Recent patch fixed an old commit
+'fc2a5a6161a2 ("powerpc/64s: ppc_save_regs is now needed for all 64s builds")'
+which is to include building of ppc_save_reg.c only when XMON
+and KEXEC_CORE and PPC_BOOK3S are enabled. 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.
