[PATCH] [next-20140923] KVM: Remove KVM_VFIO

[PATCH] [next-20140923] KVM: Remove KVM_VFIO

[Paul Bolle]

There are no checks for CONFIG_KVM_VFIO and nothing depends on KVM_VFIO.
Setting KVM_VFIO has no effect. Remove that Kconfig symbol.

I choose not to mention commit 80ce1639727e ("KVM: VFIO: register
kvm_device_ops dynamically") as references to linux-next commits might
go stale and only confuse future readers.

Done on top of next-21040923. Tested with "git grep" only.

In the case of KVM, linux-commit hashes are substantially stable.  I'll
add back the reference.

Thanks for the patch, I'll apply it.
