Convert the driver to use net_device_ops as it is now mandatory.
Also compensate for the removal of struct sk_buff's dst field.

was moved to ethernet.c and ethernet-common.{c,h} are removed.

There are some broken devices that report multiple DMA xfer modes
enabled at once (ATA spec doesn't allow it) but otherwise work fine
with DMA so just delete ide_id_dma_bug().
[ As discovered by detective work by Frans and Bart, due to how
handling of the ID block was handled before commit c419993
("ide-iops: only clear DMA words on setting DMA mode") this
check was always seeing zeros in the fields or other similar
garbage. Therefore this check wasn't actually checking anything.
Now that the tests actually check the real bits, all we see are
devices that trigger the check yet work perfectly fine, therefore
killing this useless check is the best thing to do. -DaveM ]

Frans Pop reported that his CDROM drive reports a blocksize of 2352,
and this causes new warnings due to commit
e8e7b9eb11 ("ide-cd: fix oops when using
growisofs").
What we're trying to do is make sure that "blocklen >> SECTOR_BITS"
is something the block layer won't choke on.
And for Frans' case "2352 >> SECTOR_BITS" is equal to
"2048 >> SECTOR_BITS", and thats "4".
So warning in this case gives no real benefit.

Add ide_host_enable_irqs() helper and use it in ide_host_register()

from in init_irq().
This should fix the problem with "screaming" shared IRQ on the first

on the second port) which was uncovered by my rework of the serialized

Some BIOS re-use the same processor bus id

But the (deprecated) /proc/acpi/ interface
assumes the bus-id's are unique, resulting in an OOPS

WARNING: at fs/proc/generic.c:590 proc_register+0x148/0x180()

Rename the processor device bus id. And the new bus id will be
generated as the following format:
CPU+ CPU ID
For example: If the cpu ID is 5, then the bus ID will be "CPU5".
If the CPU ID is 10, then the bus ID will be "CPUA".
Yes, this will change the directory names seen
in /proc/acpi/processor/* on some systems.
Before this patch, those directory names where
totally arbitrary strings based on the interal AML device strings.

Sometimes both acpi video and i915 driver are compiled as modules.
And there exists the strict dependency between the two drivers.
The acpi video bus will be unloaded in course of unloading the i915 driver.
If we unload the acpi video driver, then the kernel oops will be triggered.
Add the reference count to avoid unloading the ACPI video bus twice.
The reference count should be checked before unregistering the acpi video bus.
If the reference count is already zero, it won't unregister it again.
And after the acpi video bus is already unregistered, the reference count
will be set to zero.

we used to run the hotplug code in keventd_wq.
But when hot removing the ACPI battery device,
power_supply_unregister invokes flush_scheduled_work.
This causes a deadlock. i.e
1. When dock is unplugged, all the hotplug code is run on kevent_wq.
2. the hotplug code removes all the child devices of dock device.
3. removing the child device may invoke flush_scheduled_work
4. flush_scheduled_work waits until all the work on kevent_wq to be
finished, while this will never be true because the hotplug code
is running on keventd_wq...
