[Qemu-devel] [PATCH] PPC: KVM: fix compile errors by adding empty stubs for breakpoints API

[Qemu-devel] [PATCH] PPC: KVM: fix compile errors by adding empty stubs for breakpoints API

[Alexey Kardashevskiy]

The latest kernel headers update bf63839ffa2d0eebb1eb1706022f46e93b6fec08
"linux-headers: Update from v3.13-rc3" turned __KVM_HAVE_GUEST_DEBUG on
and broke the upstream for PPC64 as this API is not supported by PPC64 yet.

This adds no-op stubs (copied from target-arm/kvm.c).
