Subject: linux-next: build failure after merge of the final tree (kvm tree
 related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

cc1: warnings being treated as errors
arch/powerpc/kvm/44x_tlb.c: In function 'kvmppc_mmu_map':
arch/powerpc/kvm/44x_tlb.c:319: error: format '%lx' expects type 'long unsigned int', but argument 2 has type 'gfn_t'

Caused by commit 05c07e00b15e00632a2502dcbf253415449e89da ("KVM: Use u64
for frame data types").  I applied the following patch for today:
