Up to now, work items to be queued to be handled by pciehp_power_thread()
are allocated using kmalloc() in three different locations.  If not needed,
kfree() is called to free the allocated data.

Introduce a separate function to allocate the work item and queue it, and
call it only if needed.  This reduces code duplication and avoids having to
free memory if the work item does not need to get executed.

The PCIe spec (r3.0, sec 7.8.9) says Hot-Plug Surprise indicates support
for surprise *removal*, but pciehp checked this to determine if it should
handle presence detect interrupts for device *addition*.

Allow surprise device addition even if the slot doesn't advertise support
for surprise removal.

Keith has a platform with slots for front-loading SFF devices.  The slots
do not have attention buttons and do not support surprise removal, but they
do have presence detect.  In that case, we still want to use presence
detect for device addition.

Keith's original patch handled surprise insertions only if Hot-Plug Capable
is set.  I think that test is superfluous because pciehp only claims slots
that advertise Hot-Plug Capable (see get_port_device_capability()).

Today, this is how all the hotplug and unplug events work:

Hotplug / Removal needs to be done
  => Set slot->state (protected by slot->lock) to either
    POWERON_STATE (for enabling) or POWEROFF_STATE (for disabling).
  => Submit the work item for pciehp_power_thread() to slot->wq.

Problem:
  There is a problem if the hotplug events can happen fast enough that
  they do not give SW enough time to add or remove the new devices.

  => Assume: Event for unplug comes (e.g. surprise removal). But
     before the pciehp_power_thread() work item was executed, the
     card was replaced by another card, causing surprise hotplug event.

  => What goes wrong:
    => The hot-removal event sets slot->state to POWEROFF_STATE, and
       schedules the pciehp_power_thread().
    => The hot-add event sets slot->state to POWERON_STATE, and
       schedules the pciehp_power_thread().
    => Now the pciehp_power_thread() is scheduled twice, and on both
       occasions it will find POWERON_STATE and will try to add the
       devices on the slot, and will fail complaining that the devices
       already exist.

  => Why this is a problem: If the device was replaced between the hot
     removal and hot-add, then we should unload the old driver and
     reload the new one. This does not happen today. The kernel or the
     driver is not even aware that the device was replaced.

     The problem is that the pciehp_power_thread() only looks at the
     slot->state which would only contain the *latest* state - not
     the actual event (add / remove) that was the intent of the IRQ
     handler who submitted the work.

What this patch does:

  => Hotplug events pass on an actual request (for addition or removal)
     to pciehp_power_thread() which is local to that work item
     submission.

  => pciehp_power_thread() does not need to look at slote->state and
     hence no locks needed in that.

  => Essentially this results in all the hotplug and unplug events
     "replayed" by pciehp_power_thread().

It does not make much sense to refuse to disable a slot if an adapter is
not present or the latch is open. If an adapter is not present, it provides
an even better reason to disable the device slot.

This is specially a problem for link state hot-plug, because some ports use
in band mechanism for presence detection. Thus when link goes down,
presence detect also goes down. We _want_ that the removal should take
place in such case.

Thus remove the checks for adapter and latch in pciehp_disable_slot()

When we have a hotplug-capable PCIe port with a second hotplug-capable
PCIe port below it, removing the device below the upstream port causes
a deadlock.

The deadlock happens because we use the pciehp_wq workqueue to run
pciehp_power_thread(), which uses pciehp_disable_slot() to remove devices
below the upstream port.  When we remove the downstream PCIe port, we call
pciehp_remove(), the pciehp driver's .remove() method.  That calls
flush_workqueue(pciehp_wq), which deadlocks because the
pciehp_power_thread() work item is still running.

This patch avoids the deadlock by creating a workqueue for every PCIe port
and removing the single shared workqueue.

Here's the call path that leads to the deadlock:

  pciehp_queue_pushbutton_work
    queue_work(pciehp_wq)                   # queue pciehp_power_thread
    ...

  pciehp_power_thread
    pciehp_disable_slot
      remove_board
	pciehp_unconfigure_device
	  pci_stop_and_remove_bus_device
	    ...
	      pciehp_remove                 # pciehp driver .remove method
		pciehp_release_ctrl
		  pcie_cleanup_slot
		    flush_workqueue(pciehp_wq)

This is fairly urgent because it can be caused by simply unplugging a
Thunderbolt adapter, as reported by Daniel below.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

There is a very old quirk for the intel E7502 E7320 and E7525 memory
controller hubs that disables usage of msi interrupts on pcie hotplug
bridges of those devices, and disables changing the affinity of irqs.

Today all we have to do to disable msi on a specific device is to set
dev->no_msi, which is much more straightforward than the previous
logic.

The re-running of this fixup after pci hotplug happens below these
devices is totally bogus.  All of the state we change is pure software
state and we don't change the hardware at all.  Which means hotplug on
the lower devices doesn't have a chance to change this state.  So we
can safely remove the special case from the pciehp driver and the pcie
portdriver.

I suspect the special case was someone's expermental debug code that
slipped in. Certainly it isn't mentioned in commit
