Hi all,

Today's linux-next build (powerpc ppc44x_defconfig) failed like this:

In file included from arch/powerpc/kvm/booke.c:31:
arch/powerpc/kvm/timing.h: In function 'kvmppc_account_exit_stat':
arch/powerpc/kvm/timing.h:51: error: bit-field '<anonymous>' width not an integer constant
In file included from arch/powerpc/kvm/booke.h:26,
                 from arch/powerpc/kvm/booke_emulate.c:23:
arch/powerpc/kvm/timing.h: In function 'kvmppc_account_exit_stat':
arch/powerpc/kvm/timing.h:51: error: bit-field '<anonymous>' width not an integer constant

Presumably caused by commit 8c87df457cb58fe75b9b893007917cf8095660a0
("BUILD_BUG_ON(): fix it and a couple of bogus uses of it").

I applied the following patch for today.  This inline function is
only called from one place in one file ...
