kvm_coalesced_mmio_init() keeps to hold the addresses of a coalesced mmio
ring page and dev even after it has freed them.
This may trigger problems, e.g., if we call kvm_coalesced_mmio_free() in
kvm_destroy_vm() or kvm_vm_ioctl_register_coalesced_mmio() afterward.
This patch avoids such problems

If coalesced_mmio init fail, the kvm-coalesced_mmio_ring will be set
to NULL. If so, we should return VM_FAULT_SIGBUS in kvm_vcpu_fault()
even if vmf-pgoff == KVM_COALESCED_MMIO_PAGE_OFFSET.

This patch change the errno of ioctl KVM_[UN]REGISTER_COALESCED_MMIO
from -EINVAL to -ENXIO if no coalesced mmio dev exists.

Hi,
I'm trying to use ioeventfd/irqfds for my shared memory patch. I
followed the usage in the vhost-net patches to see how it's setup for
virtio-pci and tried to follow it as closely as I could. Despite the
call to kvm_vm_ioctl() returning 0, any writes to the assigned 4-byte
memory area do not

Not sure if this is necessary. It may be necessary when large pages come

This version may be better.

Also, if this function fails, though it must be rare, it seems to be
suggesting the system's serious state.
