Subject: linux-next: kvm tree build warning

[Not sure what happened to the previous versions To/CC lists, sorry]

Hi all,

Today's linux-next build (powerpc allyesconfig) produced this warning:

arch/powerpc/kvm/book3s.c: In function '__kvmppc_vcpu_run':
arch/powerpc/kvm/book3s.c:1102: warning: 'ext_bkp.vrsave' may be used uninitialized in this function

Introduced by commit 2609c1d06b6a7952273fb33b33ad32aff0628146 ("KVM: PPC:
Add support for FPU/Altivec/VSX").  This *may* be a false positive but
will be a problem for normal builds where warnings are treated as errors
in arch/powerpc.
