[Qemu-devel] [PATCH 36/37] kvm: Make kvm_state globally available

[Marcelo Tosatti]

From: Jan Kiszka <address@hidden>

KVM-assisted devices need access to it but we have no clean channel to
distribute a reference. As a workaround until there is a better
solution, export kvm_state for global use, though use should remain
restricted to the mentioned scenario.
