Now that the PCI core manages the 'name' for each individual

Slot detection drivers can co-exist with hotplug drivers. The names
of the detected/claimed slots may be different depending on module
load order.
For legacy reasons, we need to allow hotplug drivers to override
the slot name if a detection driver is loaded first (and they find
the same slots).
Creating and overriding slot names should be an atomic operation,
otherwise you get a locking nightmare as various drivers race to
call pci_create_slot().
pci_create_slot() is already serialized by grabbing the pci_bus_sem.
We update the API and add a 'hotplug' param, which is:
set if the caller is a hotplug driver
NULL if the caller is a detection driver
pci_create_slot() does not actually use the 'hotplug' parameter in this
patch. A later patch will add the logic that uses it.

Sometimes, it's necessary to enable software's ability to quiesce and
reset endpoint hardware with function-level granularity, so provide
support for it.
The patch implement Function Level Reset(FLR) feature following PCI-e
spec. And this is the first step. We would add more generic method, like
D0/D3, to allow more devices support this function.
The patch contains two functions. pcie_reset_function() is the new
driver API, and, contains some action to quiesce a device. The other
function is a helper: pcie_execute_reset_function() just executes the
reset for a particular device function.
Current the usage model is in KVM. Function reset is necessary for
assigning device to a guest, or moving it between partitions.
For Function Level Reset(FLR), please refer to PCI Express spec chapter
6.6.2.

Maybe the incorrect power state is returned on the bogus bios, which
is different with the real power state. For example: the bios returns D0
state and the real power state is D3. OS expects to set the device to D0
state. In such case if OS uses the power state returned by the BIOS and
checks the device power state very strictly in power transition, the device
can't be transited to the correct power state.
So the boot option of "acpi.power_nocheck=1" is added to avoid checking
the device power in the course of device power transition.

- Move it into a separate file; clean and streamline it
- Restructure the init code for reuse during secondary dispatch
- Support both levels (primary, secondary) of IRQ dispatch
- Use a workqueue for irq mask/unmask and trigger configuration
Code for two subchips currently share that secondary handler code.
One is the power subchip; its IRQs are now handled by this core,
courtesy of this patch. The other is the GPIO module, which will
be supported through a later patch.
There are also minor changes to the header file, mostly related
to GPIO support; nothing yet in mainline cares about those. A
few references to OMAP-specific symbols are disabled; when they
can all be removed, the TWL4030 support ceases being OMAP-specific.

There are a lot of one-liner uses of __setup() in the kernel: they're
cumbersome and not queryable (definitely not settable) via /sys. Yet
it's ugly to simplify them to module_param(), because by default that
inserts a prefix of the module name (usually filename).
So, introduce a "core_param". The parameter gets no prefix, but
appears in /sys/module/kernel/parameters/ (if non-zero perms arg). I
thought about using the name "core", but that's more common than
"kernel". And if you create a module called "kernel", you will die
a horrible death.
