build failure of current mmotm with skiroot_defconfig

Hi,

I've encountered the following error when building skyroot_defconfig with
current mmotm tree:

make CONFIG_OF_ALL_DTBS=y CONFIG_DTC=y CROSS_COMPILE=/opt/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ARCH=powerpc vmlinux

I can neither find the above in arch/powerpc/include/asm/kvm_ppc.h in 
the powerpc tree, nor a patch removing it.

Where does that comes from ?

It's from current mmotm, probably some merge conflict...

It's not a merge conflict; see http://patchwork.ozlabs.org/patch/1048584/
for the fix.

Why not include asm/xive.h all the time, as it defines xive_enabled() 
for when CONFIG_PPC_XIVE is set and for when it is not set ?

I wasn't sure it wouldn't break the build for 32-bit configs.
