hmmm, I'm wondering if this is actually related to:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

Can you tell me which GCC version you are using?

I have been unable to reproduce this in any way (unfortunately it seems
the randconfig generating this error is also not available anymore), but
this patch may solve the issue:

diff --git a/arch/arm/kvm/reset.c b/arch/arm/kvm/reset.c
