Export handle_edge_irq() and irq_to_desc() to modules to allow them to

	ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined!

This was introduced by commit df9541a6 ("gpio: pch9: Use proper flow
type handlers") that added

	__irq_set_handler_locked(d->irq, handle_edge_irq);

but handle_edge_irq() was not exported for modules (and inlined

Jean-Francois Dagenais reported:

 Configuring a gpio pin with the gpio-pch driver with
 "IRQF_TRIGGER_LOW | IRQF_ONESHOT" generates an interrupt storm for
 threaded ISR until the ISR thread actually gets to physically clear
 the interrupt on the triggering chip!! The immediate observable
 symptom is the high CPU usage for my ISR thread task and the
 interrupt count in /proc/interrupts incrementing radically.

The driver is wrong in several ways:

1) Using handle_simple_irq() does not provide proper flow control
   handling. In the case of oneshot threaded handlers for the
   demultiplexed interrupts this results in an interrupt storm because
   the simple handler does not deal with masking/unmasking.  Even
   without threaded oneshot handlers an interrupt storm for level type
   interrupts can easily be triggered when the interrupt is disabled
   and the interrupt line is activated from the device.

2) Acknowlegding the demultiplexed interrupt before calling the
   handler is wrong for level type interrupts.

3) The set_type function unconditionally enables the interrupt. It's
   supposed to set the type and nothing else. The unmasking is done by
   the core code.

Move the acknowledge code into a separate function and add it to the
demux irqchip callbacks.

Remove the unconditional enabling from the set_type() callback and set
the proper flow handlers depending on the selected type (level/edge).

Pull target fix from Nicholas Bellinger:
 "This patch removes some incorrect legacy code to free se_lun_acl
  memory in the NodeACL release path that could potentially trigger an
  OOPS during shutdown once dynamic -> explicit initiator NodeACL
  conversion has occurred.

  That said, we've been able to trigger an OOPS in v4.0 code for this
  special case when the associated MappedLUNs had not also been made
  explicit based on active TPG LUN layout during the conversion, so it
  really makes senses to go ahead and drop this extra cruft to avoid any
  possible issues here.

  This ends up only effecting iscsi-target module code (it's the only
  user) and is CC'ed to stable."

* '3.4-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target: Drop incorrect se_lun_acl release for dynamic -> explict ACL conversion

So we have another case of paca->irq_happened getting out of
sync with the HW irq state. This can happen when a perfmon
interrupt occurs while soft disabled, as it will return to a
soft disabled but hard enabled context while leaving a stale
PACA_IRQ_HARD_DIS flag set.

This patch fixes it, and also adds a test for the condition
of those flags being out of sync in arch_local_irq_restore()
when CONFIG_TRACE_IRQFLAGS is enabled.

This helps catching those gremlins faster (and so far I
can't seem see any anymore, so that's good news).
