else, we get memory corruption on reboot; found when tracking down
initramfs unpack error on initial reboot (with qemu-kvm -smp 2,
no problem with single-core).
problem with doing it via kvm_shutdown() is that this file
depends on CONFIG_KVM_CLOCK, also its not enough to call it for one
cpu only.

This fixes breakage introduced by the following commit:
commit 6d2d82627f4f1e96a33664ace494fa363e0495cb
Author: Liu Yu-B13201

PPC: Don't use hardcoded opcode for ePAPR hcall invocation
when a driver that uses ePAPR hypercalls is built as a module.
Registering an kvm_irq_ack_notifier with kian.irq_source_id < 0
retains existing behavior, filling in the actual irq_source_id results
in the callback only being called when the specified irq_source_id is
asserting the given gsi.
The i8254 PIT remains unfiltered because it de-asserts it's irq sour
It's likely (vfio) that one of the reasons to watch for an IRQ ACK
is to de-assert and re-enable an interrupt. As the IRQ ACK notfier
is already watching a GSI for an IRQ source ID we can easily couple
these together.

Enable a mechanism for IRQ ACKs to be exposed through an eventfd. The
user can specify the GSI and optionally an IRQ source ID and have the
provided eventfd trigger whenever the irqchip resamples it's inputs,
for instance on EOI.

v8:
Trying a new approach. Nobody seems to like the internal IRQ
source ID object and the interactions it implies between irqfd
and eoifd, so let's get rid of it. Instead, simply expose
IRQ source IDs to userspace. This lets the user be in charge
of freeing them or hanging onto a source ID for
Introduce KVM_IRQ_SOURCE_ID and KVM_CAP_NR_IRQ_SOURCE_ID to allow
user allocation of IRQ source IDs and querying both the capability
and the total count of IRQ source IDs. These will later be used
by interfaces for setting up level IRQs.

This allows specifying an IRQ source ID to be used when injecting an
interrupt. When not specified KVM_USERSPACE_IRQ_SOURCE_ID is used.

This allows specifying that an irqfd is used only to assert the
specified gsi, whereas standard behavior is to follow the assertion
with a deassertion. This will later allow a level interrupt to be
asserted via eventfd and later de-asserted by other means.
