a79d682f78 PCI PM: Split PCI Express port suspend-resume
Suspend-resume of PCI Express ports has recently been moved into
_suspend_late() and _resume_early() callbacks, but some functions
executed from there should not be called with interrupts disabled,
eg. pci_enable_device().  For this reason, split the suspend-resume
of PCI Express ports into parts to be executed with interrupts
disabled and with interrupts enabled.

90d25f246d PCI: Suspend and resume PCI Express ports with interrupts disabled
I don't see why the suspend and resume of PCI Express ports should be
handled with interrupts enabled and it may even lead to problems in
some situations.  For this reason, move the suspending and resuming
of PCI Express ports into ->suspend_late() and ->resume_early()
callbacks executed with interrupts disabled.

This patch addresses the regression from 2.6.26 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12121 .

if there are no children under a device. This leads to

3603a6a37c pcie: fix section mismatch warning
Fix following section mismatch warning (when compiled with CONFIG_HOTPLUG=n):
WARNING: drivers/pci/built-in.o - Section mismatch: reference to .init.text:pcie_portdrv_probe from .data between 'pcie_portdrv' (at offset 0xe40) and 'pcie_portdrv_err_handler'

This warning was fixed by renaming pcie_portdrv to pcie_portdriver so we pass
the whitelist.

I move the definition of pcie_portdrv_restore_config
out of CONFIG_PM.

Below patch is against 2.6.18-mm1. Could you try it?

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
