0dcb2b7e72 pci: clear osc support flags if no _OSC method
So it looks like pci aer code will call pci_osc_support_set to tell the
firmware about  OSC_EXT_PCI_CONFIG_SUPPORT flag.  that causes
ctrlset_buf[OSC_SUPPORT_TYPE] to evaluate to true when pciehp calls
pci_osc_control_set() is called (to attempt to use OSC to gain native
pcie control from firmware), regardless of whether or not _OSC was
actually successfully executed.  That causes this section of code:
 if (ctrlset_buf[OSC_SUPPORT_TYPE] &&
                ((global_ctrlsets & ctrlset) != ctrlset)) {
                return AE_SUPPORT;
        }
to be hit.

This patch will reset the OSC_SUPPORT_TYPE field if _OSC fails, and then
would allow pciehp to go ahead and try to run _OSC again.

a2302c68d9 Altix: Initial ACPI support - ROM shadowing.
Support a shadowed ROM when running with an ACPI capable PROM.

Define a new dev.resource flag IORESOURCE_ROM_BIOS_COPY to
describe the case of a BIOS shadowed ROM, which can then
be used to avoid pci_map_rom() making an unneeded call to
pci_enable_rom().

8ea6091f50 Altix: Add initial ACPI IO support
First phase in introducing ACPI support to SN.
In this phase, when running with an ACPI capable PROM,
the DSDT will define the root busses and all SN nodes
(SGIHUB, SGITIO). An ACPI bus driver will be registered
for the node devices, with the acpi_pci_root_driver being
used for the root busses. An ACPI vendor descriptor is
now used to pass platform specific information for both
nodes and busses, eliminating the need for the current
SAL calls. Also, with ACPI support, SN fixup code is no longer
needed to initiate the PCI bus scans, as the acpi_pci_root_driver
does that.

However, to maintain backward compatibility with non-ACPI capable
PROMs, none of the current 'fixup' code can been deleted, though
much restructuring has been done. For example, the bulk of the code
in io_common.c is relocated code that is now common regardless
of what PROM is running, while io_acpi_init.c and io_init.c contain
routines specific to an ACPI or non ACPI capable PROM respectively.

A new pci bus fixup platform vector has been created to provide
a hook for invoking platform specific bus fixup from pcibios_fixup_bus().

The size of io_space[] has been increased to support systems with
large IO configurations.

ebf5a24829 PCI: Use pci_generic_prep_mwi on sparc64
The setting of the CACHE_LINE_SIZE register in sparc64's pci
initialisation code isn't quite adequate as the device may have
incompatible requirements.  The generic code tests for this, so switch
sparc64 over to using it.

Since sparc64 has different L1 cache line size and PCI cache line size,
it would need to override the generic code like i386 and ia64 do.  We
know what the cache line size is at compile time though, so introduce a
new optional constant PCI_CACHE_LINE_BYTES.

does on ia64.  All we need to do is be sure that pci_cache_line_size

Using SMP_CACHE_BYTES as the default was wrong on uniprocessor machines
as it is only 8 bytes.  The default in the generic code of L1_CACHE_BYTES
is at least as good.

368c73d4f6 PCI: quirks: fix the festering mess that claims to handle IDE quirks
The number of permutations of crap we do is amazing and almost all of it
has the wrong effect in 2.6.

At the heart of this is the PCI SFF magic which says that compatibility
mode PCI IDE controllers use ISA IRQ routing and hard coded addresses
not the BAR values. The old quirks variously clears them, sets them,
adjusts them and then IDE ignores the result.

In order to drive all this garbage out and to do it portably we need to
handle the SFF rules directly and properly. Because we know the device
BAR 0-3 are not used in compatibility mode we load them with the values
that are implied (and indeed which many controllers actually
thoughtfully put there in this mode anyway).

This removes special cases in the IDE layer and libata which now knows
that bar 0/1/2/3 always contain the correct address. It means our
resource allocation map is accurate from boot, not "mostly accurate"
after ide is loaded, and it shoots lots of code. There is also lots more
code and magic constant knowledge to shoot once this is in and settled.

Been in my test tree for a while both with drivers/ide and with libata.
Wants some -mm shakedown in case I've missed something dumb or there are
corner cases lurking.

94fcda1f8a usbcore: remove unused argument in autosuspend

usb_autoresume_device() are never called with a second argument other
than 1.  This patch (as819) removes the now-redundant argument.

It also consolidates some common code between those two routines,

it includes a sizable kerneldoc update for the affected functions.

ee49fb5dc8 USB: keep count of unsuspended children
This patch (as818b) simplifies autosuspend processing by keeping track
of the number of unsuspended children of each USB hub.  This will
permit us to avoid a good deal of unnecessary work all the time; we
will no longer have to create a bunch of workqueue entries to carry
out autosuspend requests, only to have them fail because one of the
hub's children isn't suspended.

The basic idea is simple.  There already is a usage counter in the
usb_device structure for preventing autosuspends.  The patch just
increments that counter for every unsuspended child.  There's only one
tricky part: When a device disconnects we need to remember whether it
was suspended at the time (leave the counter alone) or not (decrement
the counter).

d25450c687 USB hub: simplify remote-wakeup handling
This patch (as817) simplifies the remote-wakeup processing in the hub
driver.  Now instead of using a specialized code path, it relies on
the standard USB resume routines.  The hub_port_resume() function does
an initial get_port_status() to see whether the port has already
resumed itself (as it does when a remote-wakeup request is sent).
This will slow down handling of other resume events slightly, but not
enough to matter.

The patch also changes the hub_port_status() routine, making it return
an error if a short reply is received.

1f9fc882d9 OHCI: make autostop conditional on CONFIG_PM
Unlike UHCI, OHCI does not exert any DMA load on the system when no
devices are connected.  Consequently there is no advantage to doing
an autostop other than the power savings, so we shouldn't compile the
necessary code unless CONFIG_PM is enabled.

This patch (as820) makes the root-hub suspend and resume routines
conditional on CONFIG_PM.  It also prevents autostop from activating
if the device_may_wakeup flag isn't set; some people use this flag to
alert the driver about Resume-Detect bugs in the hardware.

8c03356a55 EHCI: Fix root-hub and port suspend/resume problems
This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:

	The bus_resume() routine should wake up only the ports that
	were suspended by bus_suspend().  Ports that were already
	suspended should remain that way.

	The interrupt mask is used to detect loss of power in the
	bus_resume() routine (if the mask is 0 then power was lost).
	However bus_suspend() always sets the mask to 0.  Instead the
	mask should retain its normal value, with port-change-detect
	interrupts disabled if remote wakeup is turned off.

	The interrupt mask should be reset to its correct value at the
	end of bus_resume() regardless of whether power was lost.

	bus_resume() reinitializes the operational registers if power
	was lost.  However those registers are not in the aux power
	well, hence they can lose their values whenever the controller
	is put into D3.  They should always be reinitialized.

	When a port-change interrupt occurs and the root hub is
	suspended, the interrupt handler should request a root-hub
	resume instead of starting up the controller all by itself.

	There's no need for the interrupt handler to request a
	root-hub resume every time a suspended port sends a
	remote-wakeup request.

	The pci_resume() method doesn't need to check for connected
	ports when deciding whether or not to reset the controller.
	It can make that decision based on whether Vaux power was
	maintained.

	Even when the controller does not need to be reset,
	pci_resume() must undo the effect of pci_suspend() by
	re-enabling the interrupt mask.

	If power was lost, pci_resume() must not call ehci_run().
	At this point the root hub is still supposed to be suspended,
	not running.  It's enough to rewrite the command register and
	set the configured_flag.

93f1a47c4a USB: add ehci_hcd.ignore_oc parameter
Certain boards seem to like to issue false overcurrent notifications, for
example on ports that don't have anything connected to them.  This looks
like a hardware error, at the level of noise to those ports' overcurrent
input signals (or non-debounced VBUS comparators).  This surfaces to users
as truly massive amounts of syslog spam from khubd (which is appropriate
for real hardware problems, except for the volume from multiple ports).

Using this new "ignore_oc" flag helps such systems work more sanely, by
preventing such indications from getting to khubd (and spam syslog).  The
downside is of course that true overcurrent errors will be masked; they'll
appear as spontaneous disconnects, without the diagnostics that will let
users troubleshoot issues like short circuited cables.

Note that the bulk of these reports seem to be with VIA southbridges, but
I think some were with Intel ones.

49314378ac USB: add Digitech USB-Storage to unusual_devs.h
The mass storage device from Digitech designed for Flash Cards, as found
on (for example) the GNX4 device has issues with residue, similar to the
bug report at http://kerneltrap.org/node/6297.  This patch adds the
faulty storage device to unusual_devs.h, this not only reduces the noise
in dmesg but also increases the transfer speeds by a factor of 7x for me
(89kB/s -> 637kB/s).

Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.

1b7be3c066 OHCI: change priority level of resume log message
All the other root-hub suspend or resume log messages, in ohci-hcd or
any of the other host controller drivers, use the debug priority
level.  This patch (as815) makes the one single exception behave like
all the rest.
