Compiling with CONFIG_PPC_POWERNV=y and KVM disabled currently gives
an error like this:
CC arch/powerpc/kernel/dbell.o
In file included from arch/powerpc/kernel/dbell.c:20:0:
arch/powerpc/include/asm/kvm_ppc.h: In function ‘xics_on_xive’:
arch/powerpc/include/asm/kvm_ppc.h:625:9: error: implicit declaration of function ‘xive_enabled’ [-Werror=implicit-function-declaration]
return xive_enabled() && cpu_has_feature(CPU_FTR_HVMODE);
^
cc1: all warnings being treated as errors
scripts/Makefile.build:276: recipe for target 'arch/powerpc/kernel/dbell.o' failed
make[3]: *** [arch/powerpc/kernel/dbell.o] Error 1
Fix this by making the xics_on_xive() definition conditional on the
same symbol (CONFIG_KVM_BOOK3S_64_HANDLER) that determines whether we
include <asm/xive.h> or not, since that's the header that defines
xive_enabled().
Fixes:

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
