    Subject[PATCH v5 0/4] kvm: level irqfd and new eoifd
    - irqfds now have a one-to-one mapping with eoifds to prevent users
    from consuming all of kernel memory by repeatedly creating eoifds
    from a single irqfd.
    - implement a kvm_clear_irq() which does a test_and_clear_bit of
    the irq_state, only updating the pic/ioapic if changes and allowing
    the caller to know if anything was done. I added this onto the end
    as it's essentially an optimization on the previous design. It's
    hard to tell if there's an actual performance benefit to this.
    - dropped eoifd gsi support patch as it was only an FYI.




    Alex Williamson (4):
    kvm: Convert eoifd to use kvm_clear_irq
    kvm: Create kvm_clear_irq()
    kvm: KVM_EOIFD, an eventfd for EOIs
    kvm: Extend irqfd to support level interrupts
