We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without
swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches
to combine them).  I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup)
go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too?
But caution says still depend on MMU, since !CONFIG_MMU is.. different.

This gets rid of an annoying warning in ehci-hcd.c when DEBUG isn't
enabled:

    warning: label 'err_debug' defined but not used

by moving it inside the already-existing #ifdef DEBUG, so that it
matches the goto.  And now my regular build is warning-free again.

Yes, this will probably be switched over to a cleaner model anyway, but
in the meantime I don't want to see the 'unused variable' warnings that
come from the disgusting #ifdef code.  Make the special case be a nice
inlien function of its own, clean up the code, and make the warning go
away.

I wish people didn't write code that gets (valid) warnings from the
compiler, but I'll limit my fixes to code that I actually care about (in
this case just because I see the warning and it annoys me).

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.
