Commit78adf6c214("powerpc/64s: Implement system reset idle wakeup reason"), added a call to ppc_save_regs() in the book3s code. ppc_save_regs() is only built if XMON and/or KEXEC_CORE are enabled, which is usually the case, however if they're not enabled then the build breaks. Fix it by making the Makefile check also build ppc_save_regs.o if CONFIG_PPC_BOOK3S is enabled.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
