There was only one use of __initdata_refok and __exit_refok
__init_refok was used 46 times against 82 for __ref.
Those definitions are obsolete since commit 312b1485fb50 ("Introduce new
section reference annotations tags: __ref, __refdata, __refconst")
This patch removes the following compatibility definitions and replaces
them treewide.
/* compatibility defines */
#define __init_refok __ref
#define __initdata_refok __refdata
#define __exit_refok __ref
I can also provide separate patches if necessary.
(One patch per tree and check in 1 month or 2 to remove old definitions)

Previously, pci_scan_root_bus() created a root PCI bus, enumerated the
devices on it, and called pci_bus_add_devices(), which made the devices
available for drivers to claim them.
Most callers assigned resources to devices after pci_scan_root_bus()
returns, which may be after drivers have claimed the devices. This is
incorrect; the PCI core should not change device resources while a driver
is managing the device.
Remove pci_bus_add_devices() from pci_scan_root_bus() and do it after any
resource assignment in the callers.
Note that ARM's pci_common_init_dev() already called pci_bus_add_devices()
after pci_scan_root_bus(), so we only need to remove the first call:
pci_common_init_dev
pcibios_init_hw
pci_scan_root_bus
pci_bus_add_devices # first call
pci_bus_assign_resources
pci_bus_add_devices # second call

We currently enable PCI bridges after scanning a bus and assigning
resources. This is often done in arch code.
This patch changes this so we don't enable a bridge until necessary, i.e.,
until we enable a PCI device behind the bridge. We do this in the generic
pci_enable_device() path, so this also removes the arch-specific code to
enable bridges.

This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.
CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Pull PCI changes (including maintainer change) from Jesse Barnes:
"This pull has some good cleanups from Bjorn and Yinghai, as well as
some more code from Yinghai to better handle resource re-allocation
when enabled.
There's also a new initcall_debug feature from Arjan which will print
out quirk timing information to help identify slow quirks for fixing
or refinement (Yinghai sent in a few patches to do just that once the
new debug code landed).
Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
He's been a core PCI and Linux contributor for some time now, and has
kindly volunteered to take over. I just don't feel I have the time
for PCI review and work that it deserves lately (I've taken on some
other projects), and haven't been as responsive lately as I'd like, so
I approached Bjorn asking if he'd like to manage things. He's going
to give it a try, and I'm confident he'll do at least as well as I
have in keeping the tree managed, patches flowing, and keeping things
stable."

commit 43db595e8b5d78ce5ad2feab719814a76e3ad2e5
(sh: switch to GENERIC_PCI_IOMAP)
failed to take into account the PCI channels's
io_map_base for mapping IO BARs.
This also caused a new warning on sh.

This patch removes sh's architecture-specific 'pcibios_set_master()'

The 'latency timer' of PCI devices, both Type 0 and Type 1,
is setup in architecture-specific code [see: 'pcibios_set_master()'].
There are two approaches being taken by all the architectures - check
if the 'latency timer' is currently set between 16 and 255 and if not
bring it within bounds, or, do nothing (and then there is the
gratuitously different PA-RISC implementation).
There is nothing architecture-specific about PCI's 'latency timer' so
this patch pulls its setup functionality up into the PCI core by
creating a generic 'pcibios_set_master()' function using the '__weak'
attribute which can be used by all architectures as a default which,
if necessary, can then be over-ridden by architecture-specific code.
No functional change.

This takes a bit of a sledgehammer to the machvec I/O routines. The
iomem case requires no special casing and so can just be dropped
outright. This only leaves the ioport casing for PCI and SuperIO
mangling. With the SuperIO case going through the standard ioport
mapping, it's possible to replace everything with generic routines.
With this done the standard I/O routines are tidied up and NO_IOPORT
now gets default-enabled for the vast majority of boards.

SDK7786 supports connecting either slot3 or 4 to the same PCIe port by
way of FPGA muxing. By default the vertical slot 3 on the baseboard is
enabled, so this adds in a command line option for forcibly enabling the

If nothing has been specified on the command line, we fall back to
reading the resistor values for card presence to figure out where to

This copies the pci_config_lock idea from x86 over, allowing us to kill

pcibios_fixup_device_resources() presently skips over resources flagged
with IORESOURCE_PCI_FIXED, which is a remnant of the old PCI-auto code.
The only user for this at present is the Dreamast GAPSPCI code which
can't tolerate any adjustments to the BARs, but a combination of the
IORESOURCE_PCI_FIXED and zeroed out hose offsets does the right thing for
this case already, so we simply kill off the special casing.

This set of changes allows the SH to be built with GENERIC_IOMAP
