Commit 783ea7d4eeefe895f2731fe73ac951e94418927b
(Driver Core: Rework platform suspend/resume, print warning)
added a warning message printed for platform drivers that use the
legacy PM callbacks rather than struct dev_pm_ops. Unfortunately,
this resulted in some confusion and made some people try to convert
drivers by replacing the old callbacks with struct dev_pm_ops in
automatic way, which generally is not a good idea.
Remove the platform device runtime dev_pm_ops warning for now,
because it's annoying to users and it's not really necessary right
now.

I just debugged an obscure crash caused by a device_del() of a all NULL'd
out struct device (in usb-serial) and found that a patch like this one would
have saved me time (in addition to improved chances of a bug report from
users hitting similar driver bugs).

The f_dev in _request_firmware() is allocated via the fw_setup_device()
and fw_register_device() calls and its class set to firmware_class (the
class release function is fw_dev_release).
Commit 6acf70f078ca replaced the kfree(dev) in fw_dev_release() with a
put_device() call but my understanding is that the release function is
called via put_device -> kobject_put -> kref_put -> koject_release etc.
and it should call kfree since it's the last to see this device
structure alive.
Because of that, the _request_firmware() function on its -ENOENT error
path only calls device_unregister(f_dev) which would eventually call
fw_dev_release() but there is no kfree (the subsequent put_device call
would just make the kref negative).

This patch reworks the platform driver code for legacy
suspend and resume to avoid installing callbacks in
struct device_driver. A warning is also added telling
users to update the platform driver to use dev_pm_ops.
The functions platform_legacy_suspend()/resume() directly
call suspend and resume callbacks in struct platform_driver
instead of wrapping things in platform_drv_suspend()/resume().

This patch (as1241) renames a bunch of functions in the PM core.
Rather than go through a boring list of name changes, suffice it to
say that in the end we have a bunch of pairs of functions:
device_resume_noirq dpm_resume_noirq
device_resume dpm_resume
device_complete dpm_complete
device_suspend_noirq dpm_suspend_noirq
device_suspend dpm_suspend
device_prepare dpm_prepare
in which device_X does the X operation on a single device and dpm_X
invokes device_X for all devices in the dpm_list.
In addition, the old dpm_power_up and device_resume_noirq have been
combined into a single function (dpm_resume_noirq).
Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions
of the former top-level device_suspend and device_resume routines.

Rename the functions performing "_noirq" dev_pm_ops
operations from device_power_down() and device_power_up()
to device_suspend_noirq() and device_resume_noirq().
The new function names are chosen to show that the functions
are responsible for calling the _noirq() versions to finalize
the suspend/resume operation. The current function names do
not perform power down/up anymore so the names may be misleading.
Global function renames:
- device_power_down() -> device_suspend_noirq()
- device_power_up() -> device_resume_noirq()
Static function renames:
- suspend_device_noirq() -> __device_suspend_noirq()
- resume_device_noirq() -> __device_resume_noirq()

We shouldn't hold dpm_list_mtx while executing
[disable|enable]_nonboot_cpus(), because theoretically this may lead
to a deadlock as shown by the following example (provided by Johannes
Berg):
CPU 3 CPU 2 CPU 1
suspend/hibernate
something:
rtnl_lock() device_pm_lock()
-> mutex_lock(&dpm_list_mtx)
mutex_lock(&dpm_list_mtx)
linkwatch_work
-> rtnl_lock()
disable_nonboot_cpus()
-> flush CPU 3 workqueue
Fortunately, device drivers are supposed to stop any activities that
might lead to the registration of new device objects way before
disable_nonboot_cpus() is called, so it shouldn't be necessary to
hold dpm_list_mtx over the entire late part of device suspend and
early part of device resume.
Thus, during the late suspend and the early resume of devices acquire
dpm_list_mtx only when dpm_list is going to be traversed and release
it right after that.
This patch is reported to fix the regressions tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=13245.

Rather than calling vmalloc() repeatedly to grow the firmware image as
we receive data from userspace, just allocate and fill individual pages.
Then vmap() the whole lot in one go when we're done.
A quick test with a 337KiB iwlagn firmware shows the time taken for
request_firmware() going from ~32ms to ~5ms after I apply this patch.

This reverts commit 006f4571a15fae3a0575f2a0f9e9b63b3d1012f8:
This patch moves platform_data from struct device into
struct platform_device, based on the two ideas:
1. Now all platform_driver is registered by platform_driver_register,
which makes probe()/release()/... of platform_driver passed parameter
of platform_device *, so platform driver can get platform_data from
platform_device;
2. Other kind of devices do not need to use platform_data, we can
decrease size of device if moving it to platform_device.
Taking into consideration of thousands of files to be fixed and they
can't be finished in one night(maybe it will take a long time), so we
keep platform_data in device to allow two kind of cases coexist until
all platform devices pass its platfrom data from
platform_device->platform_data.
All patches to do this kind of conversion are welcome.
As we don't really want to do it, it was a bad idea.

To make the conversion easily, we allow platform specific data

driver may use it from struct device or struct platform_device.

There is currently only one way for userspace to say "wait for my storage
device to get ready for the modules I just loaded": to load the
scsi_wait_scan module. Expectations of userspace are that once this
module is loaded, all the (storage) devices for which the drivers
were loaded before the module load are present.
Now, there are some issues with the implementation, and the async
stuff got caught in the middle of this: The existing code only
waits for the scsy async probing to finish, but it did not take
into account at all that probing might not have begun yet.
(Russell ran into this problem on his computer and the fix works for him)
This patch fixes this more thoroughly than the previous "fix", which
had some bad side effects (namely, for kernel code that wanted to wait for
the scsi scan it would also do an async sync, which would deadlock if you did
it from async context already.. there's a report about that on lkml):
The patch makes the module first wait for all device driver probes, and then it
will wait for the scsi parallel scan to finish.

it turns that dev->dev.kobj name is changed after device_add.
for pci code: via acpi_pci_root_driver.ops.add (aka acpi_pci_root_add)
==> pci_acpi_scan_root is used to scan pci bus/device, and at the same
time we read the resource for pci_dev in the pci_read_bases, we have
res->name = pci_name(pci_dev); pci_name is calling dev_name.
later via acpi_pci_root_driver.ops.start (aka acpi_pci_root_start) ==>
pci_bus_add_device to add all pci_dev in kobj tree. pci_bus_add_device
will call device_add.

V3 of the early platform driver implementation.
Platform drivers are great for embedded platforms because we can separate
driver configuration from the actual driver. So base addresses,
interrupts and other configuration can be kept with the processor or board
code, and the platform driver can be reused by many different platforms.
For early devices we have nothing today. For instance, to configure early
timers and early serial ports we cannot use platform devices. This
because the setup order during boot. Timers are needed before the
platform driver core code is available. The same goes for early printk
support. Early in this case means before initcalls.
These early drivers today have their configuration either hard coded or
they receive it using some special configuration method. This is working
quite well, but if we want to support both regular kernel modules and
early devices then we need to have two ways of configuring the same
driver. A single way would be better.
The early platform driver patch is basically a set of functions that allow
drivers to register themselves and architecture code to locate them and
probe. Registration happens through early_param(). The time for the
probe is decided by the architecture code.
See Documentation/driver-model/platform.txt for more details.

Use the functions introduced in by the previous patch,
suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(),
to rework the handling of interrupts during suspend (hibernation) and
resume. Namely, interrupts will only be disabled on the CPU right
before suspending sysdevs, while device drivers will be prevented
from receiving interrupts, with the help of the new helper function,
before their "late" suspend callbacks run (and analogously during
resume).
In addition, since the device interrups are now disabled before the
CPU has turned all interrupts off and the CPU will ACK the interrupts
setting the IRQ_PENDING bit for them, check in sysdev_suspend() if
any wake-up interrupts are pending and abort suspend if that's the
case.
