Second PPC KVM update for 5.1
- Fix an error in compiling for the powernv platform with KVM disabled.
KVM: PPC: Fix compilation when KVM is not enabled
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().
