40b313608a Finally eradicate CONFIG_HOTPLUG
Ever since commit 45f035ab9b ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off.  Remove all the remaining references to it.

6037a803b0 PCI: acpiphp: Convert acpiphp to be builtin only, not modular
Convert acpiphp to be builtin only, with no module option.

Previously, when HOTPLUG_PCI_ACPI=m, users could disable acpiphp by
removing the module or preventing it from loading.  That can't be done
if acpiphp is builtin statically, so this adds an "acpiphp.disable"
kernel parameter.  If a user needs to use this parameter, it is a bug,
and we want to hear about it.

[bhelgaas: fold in acpiphp.disable here, remove documentation]

7441b0627e s390/pci: PCI hotplug support via SCLP
Add SCLP PCI configure/deconfigure and implement a PCI hotplug
controller (s390_pci_hpc). The hotplug controller creates a slot
for every PCI function in stand-by or configured state. The PCI
functions are named after the PCI function ID (fid). By writing to
the power attribute in /sys/bus/pci/slots/<fid>/power the PCI function
is moved to stand-by or configured state. If moved to the configured
state the device is automatically scanned by the s390 PCI layer.

c2b5acc3a3 PCI: Remove the fakephp driver
The fakephp driver was scheduled for removal in 2011.

Fakephp presented /sys/bus/pci/slots/.../power files for every PCI
function.  Writing "0" to one of these files logically removed the device
from the system.  The PCI core now provides the same functionality with
/sys/bus/pci/devices/.../remove.

268a03a42d PCI: drivers/pci/slot.c should depend on CONFIG_SYSFS
There is no way to interact with a physical PCI slot without
sysfs, so encode the dependency and prevent this build error:

	drivers/pci/slot.c: In function 'pci_hp_create_module_link':
	drivers/pci/slot.c:327: error: 'module_kset' undeclared

This patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too,
but we cannot (yet) because the PCI core merrily assumes the
existence of sysfs:

	drivers/built-in.o: In function `pci_bus_add_device':
	drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files'
	drivers/built-in.o: In function `pci_stop_dev':
	drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files'

So do the minimal bit for now and figure out how to untangle it
later.

12a9da0fcb PCI Hotplug: cpqphp: don't use pci_find_slot()
Convert uses of pci_find_slot to modern API.

In the conversion sites, we end up calling pci_dev_put() right away.

This may seem like it misses the entire point of doing something like
pci_get_bus_and_slot(), since we drop the reference so soon, but it turns
out we don't actually do much with the returned pci_dev.

I plan on untangling cpqphp further, but clearly cpqphp never worried too
much about a properly refcounted pci_dev anyway. For now, this conversion
seems reasonable, as it gets rid of the last in-tree caller of pci_find_slot.

b5240b32b9 ACPIPHP: allow acpiphp to build without ACPI_DOCK
Change the build options for acpiphp so that it may build without being
dependent on the ACPI_DOCK option, but yet does not allow the option of
acpiphp being built-in when dock is built as a module.
This does not change the previous patch for ACPI_IBM_DOCK Kconfig.

For the following matrix of config options, I built an i386 kernel.

Dock		acpiphp		should it build?	confirmed
y		y		y			y
y		n		y			y
y		m		y			y
m		y		no - acpiphp should	acpiphp was

135c294fa3 [PATCH] don't select CONFIG_HOTPLUG
It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing
and for section-checking coverage.  But a few things go and select
CONFIG_HOTPLUG, making it a royal PITA to turn the thing off.

It's only turnable offable if CONFIG_EMBEDDED anyway.  So let's make those
things depend on HOTPLUG, not select it.

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!
