    powerpc/kvm/booke: Fix build break due to stack frame size warning · f5f97210
    Scott Wood authored
    Commit ce11e48b ("KVM: PPC: E500: Add
    userspace debug stub support") added "struct thread_struct" to the
    stack of kvmppc_vcpu_run().  thread_struct is 1152 bytes on my build,
    compared to 48 bytes for the recently-introduced "struct debug_reg".
    Use the latter instead.
    
    This fixes the following error:
    
    cc1: warnings being treated as errors
    arch/powerpc/kvm/booke.c: In function 'kvmppc_vcpu_run':
    arch/powerpc/kvm/booke.c:760:1: error: the frame size of 1424 bytes is larger than 1024 bytes
