This was fixed with:

commit ad36cb0d1d3e2b7f161cd33932433f9349cade1e

    powerpc/kvm/book3s_32: Fix MTMSR_EERI macro
    
    Commit b38c77d82e4 moved the MTMSR_EERI macro from the KVM code to generic
    ppc_asm.h code. However, while adding it in the headers for the ppc32 case,
    it missed out to remove the former definition in the KVM code.
    
    This patch fixes compilation on server type PPC32 targets with CONFIG_KVM
    enabled.

which is in 3.6-rc1.  Already in rawhide.
