Subject: [PATCH 0/3] KVM: Fixes and a cleanup for coalesced MMIO

Fix two bugs that are exposed if unregistered a device on an I/O bus fails
due to OOM.  Tack on opportunistic cleanup in the related code.
 
Sean Christopherson (3):
  KVM: Destroy I/O bus devices on unregister failure _after_ sync'ing
    SRCU
  KVM: Stop looking for coalesced MMIO zones if the bus is destroyed
  KVM: Add proper lockdep assertion in I/O bus unregister
