Commit 7c08c9ae ("efifb/imacfb

merge its DMI table into the efifb driver.  So far so good, but the diff
actually ended up just generating an empty file instead of removing it.

in sysfs on platforms that support it. This will allow to clean up
X to use this instead of /dev/mem for legacy IO accesses such as
those performed by Int10.

This patch uniformizes PCI probing debug boot messages with dev_printk()
intead of manual printk()

It changes adress range output from [%llx, %llx] to [%#llx-%#llx], like
in pci_request_region().

For example, it goes from the mixed-style:

PCI: 0000:00:1b.0 reg 10 64bit mmio: [f4280000, f4283fff]
pci 0000:00:1b.0: PME# supported from D0 D3hot D3cold

to uniform:

pci 0000:00:1b.0: reg 10 64bit mmio: [0xf4280000-0xf4283fff]
pci 0000:00:1b.0: PME# supported from D0 D3hot D3cold

Since patch 6ac665c6 my infiniband
controller hasn't worked.  This is because it has 64-bit prefetchable
memory, which was mistakenly being  taken to be 32-bit memory.  The
resource flags in this case are PCI_BASE_ADDRESS_MEM_TYPE_64 |
PCI_BASE_ADDRESS_MEM_PREFETCH.

This patch checks only for the PCI_BASE_ADDRESS_MEM_TYPE_64 bit; thus
whether the region is prefetchable or not is ignored.  This fixes my
Infiniband.

The introduction of struct pci_slot (f46753c5)
added a struct pci_slot pointer to struct pci_dev, but we forgot to
associate the two.

Connect the two structs together; the interesting portions of the object
lifetimes are:

	- when a new pci_slot is created, connect it to the appropriate
	  pci_dev's. A single pci_slot may be associated with multiple
	  pci_dev's, e.g. any multi-function PCI device.

	- when a pci_slot is released, look for all the pci_dev's it was
	  associated with, and set their pci_slot pointers to NULL

	- when a pci_dev is created, look for slots to associate with.

Note -- when a pci_dev is released, we don't need to do any bookkeeping,
since pci_slot's do not have pointers to pci_dev's.

Many device drivers use the following sequence of statements to enable
the device to wake up the system while being in the D3_hot or D3_cold
low power state:

        pci_enable_wake(pdev, PCI_D3hot, 1);
        pci_enable_wake(pdev, PCI_D3cold, 1);

However, the second call is not necessary if the first one succeeds (the
ordering of the statements above doesn't matter here) and it may even be
harmful, because we are not supposed to enable PME# after the wake-up
power has been enabled for the device.

To allow drivers to overcome this problem, introduce function
pci_wake_from_d3() that will enable the device to wake up the system
from any of D3_hot and D3_cold as long as the wake-up from at least one
of them is supported.

The driver flag dynids.use_driver_data is almost consistently not set,
and causes more problems than it solves.  It was initially intended as a
flag to indicate whether a driver's usage of driver_data had been
carefully inspected and was ready for values from userspace.  That audit
was never done, so most drivers just get a 0 for driver_data when new
IDs are added from userspace via sysfs.  So remove the flag, allowing
drivers to see the data directly (a followon patch validates the passed
driver_data value against what the drivers expect).

Tejun's commit 7b595756 made sysfs
attribute->owner unnecessary.  But the field was left in the structure to
ease the merge.  It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!

This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 .  We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test.  Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.

akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'.  But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.
