cpu/hotplug: Remove unused but set variable in _cpu_down()

commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC
chip and did not add it to the new IO-APIC-IR irq chip.

Unfortunately the software resend fallback is not enabled on X86, so edge
interrupts which are received during the lazy disabled state of the
interrupt line are not retriggered and therefor lost.

Restore the callbacks.

After the recent removal of the hotplug notifiers the variable 'hasdied' in
_cpu_down() is set but no longer read, leading to the following GCC warning
when building with 'make W=1':

kernel/cpu.c:767:7: warning: variable ‘hasdied’ set but not used [-Wunused-but-set-variable]

Fix it by removing the variable.

Declare virtio_config_ops structure as const as it is only stored in the
config field of a virtio_device structure. This field is of type const, so
virtio_config_ops structures having this property can be declared const.

Mathieu reported that the LTTNG modules are broken as of 4.10-rc1 due to
the removal of the cpu hotplug notifiers.

Usually I don't care much about out of tree modules, but LTTNG is widely
used in distros. There are two ways to solve that:

1) Reserve a hotplug state for LTTNG

2) Add a dynamic range for the prepare states.

While #1 is the simplest solution, #2 is the proper one as we can convert
in tree users, which do not care about ordering, to the dynamic range as
well.

Add a dynamic range which allows LTTNG to request states in the prepare
stage.

Pull namespace fixes from Eric Biederman:
"This tree contains 4 fixes.

The first is a fix for a race that can causes oopses under the right
circumstances, and that someone just recently encountered.

Past that are several small trivial correct fixes. A real issue that
was blocking development of an out of tree driver, but does not appear
to have caused any actual problems for in-tree code. A potential
deadlock that was reported by lockdep. And a deadlock people have
experienced and took the time to track down caused by a cleanup that
removed the code to drop a reference count"

Pull USB fixes from Greg KH:
"Here are a few small USB fixes for 4.10-rc5.

Most of these are gadget/dwc2 fixes for reported issues, all of these
have been in linux-next for a while. The last one is a single xhci
WARN_ON removal to handle an issue that the dwc3 driver is hitting in
the 4.10-rc tree. The warning is harmless and needs to be removed, and
a "real" fix that is more complex will show up in 4.11-rc1 for this
device.

That last patch hasn't been in linux-next yet due to the weekend
timing, but it's a "simple" WARN_ON() removal so what could go wrong?
:)"

Famous last words.

* tag 'usb-4.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
