Implements the three basic operations provided by the stack's control
interface to WiMAX devices:
- Messaging channel between user space and driver/device
This implements a direct communication channel between user space
and the driver/device, by which free form messages can be sent back
and forth.
This is intended for device-specific features, vendor quirks, etc.
- RF-kill framework integration
Provide most of the RF-Kill integration for WiMAX drivers so that
all device drivers have to do is after wimax_dev_add() is call
wimax_report_rfkill_{hw,sw}() to update initial state and then every
time it changes.
Provides wimax_rfkill() for the kernel to call to set software
RF-Kill status and/or query current hardware and software switch
status.
Exports wimax_rfkill() over generic netlink to user space.
- Reset a WiMAX device
Provides wimax_reset() for the kernel to reset a wimax device as
needed and exports it over generic netlink to user space.
This API is clearly limited, as it still provides no way to do the
basic scan, connect and disconnect in a hardware independent way. The
WiMAX case is more complex than WiFi due to the way networks are
discovered and provisioned.
The next developments are to add the basic operations so they can be
offerent by different drivers. However, we'd like to get more vendors
to jump in and provide feedback of how the user/kernel API/abstraction
layer should be.
The user space code for the i2400m, as of now, uses the messaging
channel, but that will change as the API evolves.

Add an EXPORT_SYMBOL() to genl_unregister_mc_group(), to allow
unregistering groups on the run. EXPORT_SYMBOL_GPL() is not used as
the rest of the functions exported by this module (eg:
genl_register_mc_group) are also not _GPL().
Cleanup is currently done when unregistering a family, but there is
no way to unregister a single multicast group due to that function not
being exported. Seems to be a mistake as it is documented as for
external consumption.
This is needed by the WiMAX stack to be able to cleanup unused mc
groups.

Implements the basic life cycles of a 'struct wimax_dev', some common
generic netlink functionality for marshalling calls to user space,
and the device state machine.
For looking up net devices based on their generic netlink family IDs,
use a low overhead method that optimizes for the case where most
systems have a single WiMAX device, or at most, a very low number of
WiMAX adaptors.

This file contains a simple debug framework that is used in the stack;
it allows the debug level to be controlled at compile-time (so the
debug code is optimized out) and at run-time (for what wasn't compiled
out).
This is eventually going to be moved to use dynamic_printk(). Just
need to find time to do it.

In the same spirit as debugfs_create_*(), introduce helpers for
exporting size_t values over debugfs.
The only trick done is that the format verifier is kept at %llu
instead of %zu; otherwise type warnings would pop up:
format ‘%zu’ expects type ‘size_t’, but argument 2 has type ‘long long unsigned int’
There is no real way to fix this one--however, we can consider %llu
and %zu to be compatible if we consider that we are using the same for
validating in debugfs_create_{x,u}{8,16,32}().

to deny service, it checked only for USB_FULL_SPEED, thus

This patch (as1197) fixes an error introduced recently. Since a
significant number of devices can't handle Set-Interface requests, we
no longer call usb_set_interface() when a driver unbinds from an
interface, provided the interface is already in altsetting 0. However
the interface still does get disabled, and the call to
usb_set_interface() was the only thing re-enabling it. Since the
interface doesn't get re-enabled, further attempts to use it fail.
So the patch adds a call to usb_enable_interface() when a driver
unbinds and the interface is in altsetting 0. For this to work
right, the interface's endpoints have to be re-enabled but their
toggles have to be left alone. Therefore an additional argument is
added to usb_enable_endpoint() and usb_enable_interface(), a flag
indicating whether or not the endpoint toggles should be reset.
This is a forward-ported version of a patch which fixes Bugzilla
#12301.

This patch (as1195) eliminates a potential problem identified by
Oliver Neukum. When a driver queues an asynchronous Set-Config
request using usb_driver_set_configuration(), the request should be
cancelled if userspace changes the configuration first. The patch
introduces a linked list of pending async Set-Config requests, and
uses it to invalidate the requests for a particular device whenever
that device's configuration is set.

This patch (as1192) rearranges the USB PCI host controller suspend and
resume and resume routines:
Use pci_wake_from_d3() for enabling and disabling wakeup,
instead of pci_enable_wake().
Carry out the actual state change while interrupts are
disabled.
Change the order of the preparations to agree with the
general recommendation for PCI devices, instead of
messing around with the wakeup settings while the device
is in D3.
In .suspend:
Call the underlying driver to disable IRQ
generation;
pci_wake_from_d3(device_may_wakeup());
pci_disable_device();
In .suspend_late:
pci_save_state();
pci_set_power_state(D3hot);
(for PPC_PMAC) Disable ASIC clocks
In .resume_early:
(for PPC_PMAC) Enable ASIC clocks
pci_set_power_state(D0);
pci_restore_state();
In .resume:
pci_enable_device();
pci_set_master();
pci_wake_from_d3(0);
Call the underlying driver to reenable IRQ
generation
Add the necessary .suspend_late and .resume_early method
pointers to the PCI host controller drivers.

This patch (as1194) makes usb-storage set the CAPACITY_HEURISTICS flag
for all devices made by Nokia, Nikon, or Motorola. These companies
seem to include the READ CAPACITY bug in all of their devices.
Since cell phones and digital cameras rely on flash storage, which
always has an even number of sectors, setting CAPACITY_HEURISTICS
shouldn't cause any problems. Not even if the companies wise up and
start making devices without the bug.
A large number of unusual_devs entries are now unnecessary, so the
patch removes them.

This patch (as1189b) adds some hacks to usb-storage for dealing with
the growing problems involving bad capacity values and last-sector
accesses:
A new flag, US_FL_CAPACITY_OK, is created to indicate that
the device is known to report its capacity correctly. An
unusual_devs entry for Linux's own File-backed Storage Gadget
is added with this flag set, since g_file_storage always
reports the correct capacity and since the capacity need
not be even (it is determined by the size of the backing
file).
An entry in unusual_devs.h which has only the CAPACITY_OK
flag set shouldn't prejudice libusual, since the device will
work perfectly well with either usb-storage or ub. So a
new macro, COMPLIANT_DEV, is added to let libusual know
about these entries.
When a last-sector access succeeds and the total number of
sectors is odd (the unexpected case, in which guessing that
the number is even might cause trouble), a WARN is triggered.
The kerneloops.org project will collect these warnings,
allowing us to add CAPACITY_OK flags for the devices in
question before implementing the default-to-even heuristic.
If users want to prevent the stack dump produced by the WARN,
they can disable the hack by adding an unusual_devs entry
for their device with the CAPACITY_OK flag.
When a last-sector access fails three times in a row and
neither the FIX_CAPACITY nor the CAPACITY_OK flag is set,
we assume the last-sector bug is present. We replace the
existing status and sense data with values that will cause
the SCSI core to fail the access immediately rather than
retry indefinitely. This should fix the difficulties
people have been having with Nokia phones.

Many newer Option mobile broadband devices initially provide a

any software on it most likely wouldn't be compatible with your
kernel or distro anyway. Thus, by default just kill the driver
CD device by sending the SCSI 'rezero' command, but allow override
of the default behavior via usb-storage module parameter so users
can keep the ZeroCD device if they really want to. Inspired by

This patch (as1185) makes usbcore take advantage of the bus
notifications sent out by the driver core. Now we can create all our
device and interface attribute files before the device or interface
uevent is broadcast.
A side effect is that we no longer create the endpoint "pseudo"
devices at the same time as a device or interface is registered -- it
seems like a bad idea to try registering an endpoint before the
registration of its parent is complete. So the routines for creating
and removing endpoint devices have been split out and renamed, and
they are called explicitly when needed. A new bitflag is used for
keeping track of whether or not the interface's endpoint devices have
been created, since (just as with the interface attributes) they vary
with the altsetting and hence can be changed at random times.

The DPCM subdriver is a little peculiar, in that it's meant to support
devices where LUN 0 is Compact Flash and uses the CB transport whereas
LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't
really a transport in itself; it's more like a demultiplexer.
Much of the DPCM code is part of the SDDR09 subdriver already, and the
remaining part is fairly small. This patch (as1182) moves that extra
piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is
the Kconfig entry for DPCM support; it is now listed as part of the
SDDR09 entry.
In order to make sure that the semantics are the same as before, each
unusual_devs entry for DPCM is now present twice: once with DPCM
support if SDDR09 is configured (as before), and once with the

This should speed up the option driver's upload speed quite a bit. It has been tested by a number of different people on different devices with success.

Some of the usb-serial drivers are starting to use urb->status in ways
they should not be doing. This fixes up some of them to prevent that.

Contains fixes so probe on x86 PCI runs, apparently I'm first to try
this. Several fixes to memory access to probe host scratch register.
Previously would bug check on chip_addr var used uninitialized.
Scratch reg write failed in one instance due to 16-bit initial access
mode, so added "& 0x0000ffff" to the readl as fix.
Includes some general cleanup - remove global vars, organize memory map
resource use.

this driver can't handle (of course) any brdige class devices. So we
now are just active on one specific bridge which should be only the
isp1761 chip behind a PLX bridge.

In some obscure scenarios e.g. passing a 0-byte backing file
storage, wait_for_completion() would wait forever in fsg_cleanup().
Prevent it by completing the thread in fsg_bind() error path.

This patch (as1177) modifies the USB core suspend and resume
routines. The resume functions now will take a pm_message_t argument,
so they will know what sort of resume is occurring. The new argument
is also passed to the port suspend/resume and bus suspend/resume
routines (although they don't use it for anything but debugging).
In addition, special pm_message_t values are used for user-initiated,
device-initiated (i.e., remote wakeup), and automatic suspend/resume.
By testing these values, drivers can tell whether or not a particular
suspend was an autosuspend. Unfortunately, they can't do the same for
resumes -- not until the pm_message_t argument is also passed to the
drivers' resume methods. That will require a bigger change.
IMO, the whole Power Management framework should have been set up this
way in the first place.

This patch (as1178) uses the new round_jiffies_up_relative() routine
for setting the autosuspend delayed_work timer. It's appropriate
since we don't care too much about the exact length of the delay, but
we don't want it to be too short (rounded down).

Move otg_get/set/put_transceiver() from omap specific code
to common otg.c so other upcoming drivers can share them.
