USB: ehci-hcd unlink speedups
This patch fixes some performance bugs observed with some workloads
when unlinking EHCI queue header (QH) descriptors from the async ring
(control/bulk schedule).
The mechanism intended to defer unlinking an empty QH (so there is no
penalty in common cases where it's quickly reused) was not working as
intended. Sometimes the unlink was scheduled:
- too quickly ... which can be a *strong* negative effect, since
that QH becomes unavailable for immediate re-use;
- too slowly ... wasting DMA cycles, usually a minor issue except
for increased bus contention and power usage;
Plus there was an extreme case of "too slowly": a logical error in the
IAA watchdog-timer conversion meant that sometimes the unlink never
got scheduled.
The fix replaces a simple counter with a timestamp derived from the
controller's 8 KHz microframe counter, and adjusts the timer usage
for some issues associated with HZ being less than 8K.

from Leonid.)

USB: ohci_hcd hang: submit vs. rmmod race
If we do rmmod ohci_hcd while an application is doing something, the
following may happen:
- a control URB completes (in finish_urb) and the ohci's endpoint is
set into ED_UNLINK in ed_deschedule
- same URB is (re)submitted because of the open/close loop or other
such application behaviour
- rmmod sets the state to HC_STATE_QUESCING
- finish_unlinks happens at next SOF; normally it would set ed into
ED_IDLE and immediately call ed_schedule (since URB had extra TDs
queued), which sets it into ED_OPER. But the check in ed_schedule
makes it fail with -EAGAIN (which is ignored)
- from now on we have a dead URB stuck; it cannot even be unlinked
because the ed status is not ED_OPER, and thus start_ed_unlink is
not invoked.
This patch removes the check. In 2.6.25, all callers check for
__ACTIVE bit before invoking ed_schedule, which is more appropriate.

the all-in-one Ethernet gadget driver into a component that can be
called by various functions, so the various flavors can be split
apart and selectively reused.
A notable difference from the approach taken with the serial link
layer code (beyond talking to NET not TTY) is that because of the
initialization requirements, this only supports one network link.
(And one set of Ethernet link addresses.)
That is, each configuration may have only one instance of a network
function. This doesn't change behavior; the current code has that
same restriction. If you want multiple logical links, that can
easily be done using network layer tools.

usb gadget: RNDIS cleanups
Some cleanup to the RNDIS code:
- Minor bugfix: rndis_unit() is supposed to put the link into the
RNDIS_UNINITIALIZED state, which does not mean "unused". There's
a separate method to stop using the link. (Bug doesn't affect
anything right now because of how the code is used.)
- Reduce coupling between RNDIS code and its user(s), in preparation
for updates in that code:
* Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device
by passing just a void* handle. (Also, remove the unused return
value of the notification callback.)
* When it needs a copy of net_device stats, just ask for it
- Remove unused/untested code backing various never-used OIDs:
* RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the
relevant docs were unclear, ambguous, and incomplete. Someone
with access to the Hidden Gospels (maybe in the EU?) might be
able to figure out what this should do.
* RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never
implemented in part because not all the semantics were clear.
* OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever.
- A few small whitespace fixes
Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style.
There should be no functional changes because of this patch; it's a
net source code shrink (because of the dead/unused code removal) and
a small object code shrink (a couple hundred bytes on ARMv5).

usb gadget: composite gadget core

- struct usb_configuration ... groups one or more such functions into
a configuration managed as one unit by a driver, to which it's added

- struct usb_composite_driver ... groups one or more such configurations

How to use it (the short version): provide a usb_composite_driver with a
bind() that calls usb_add_config() for each of the needed configurations.
The configurations in turn have bind() calls, which will usb_add_function()
for each function required. Each function's bind() allocates resources

usb gadget: descriptor copying support
Define three new descriptor manipulation utilities, for use when
setting up functions that may have multiple instances:
usb_copy_descriptors() to copy a vector of descriptors
usb_free_descriptors() to free the copy
usb_find_endpoint() to find a copied version
These will be used as follows. Functions will continue to have static
tables of descriptors they update, now used as __initdata templates.
When a function creates a new instance, it patches those tables with
relevant interface and string IDs, plus endpoint assignments. Then it
copies those morphed descriptors, associates the copies with the new
function instance, and records the endpoint descriptors to use when
activating the endpoints. When initialization is done, only the copies
remain in memory. The copies are freed on driver removal.
This ensures that each instance has descriptors which hold the right
instance-specific data. Two instances in the same configuration will
obviously never share the same interface IDs or use the same endpoints.
Instances in different configurations won't do so either, which means
this is slightly less memory-efficient in some cases.
This also includes a bugfix to the epautoconf code that shows up with
this usage model. It must replace the previous endpoint number when
updating the template descriptors, not just mask in a few more bits.

It also changed some behaviors for the better:
- Stops using "experimental" major #127, and switches over to

- Provides /sys/class/tty/ttyGS* nodes, thus mdev/udev support.
(Note "mdev" hotplug bug in Busybox v1.7.2: /dev/ttyGS0 will
be a *block* device without CONFIG_SYSFS_DEPRECATED_V2.)
- The tty nodes no longer reject opens when there's no host.
Now they can support normal getty configs in /etc/inttab...
- Now implements RX throttling. When the line discipline says
it doesn't want any more data, only packets in flight will be
delivered (currently, max 1K/8K at full/high speeds) until it
unthrottles the data.
- Supports low_latency. This is a good policy for all USB serial

usb-storage: implement "soft" unbinding
This patch (as1092) implements "soft" unbinding for usb-storage. When
the disconnect routine is called, all commands and reset delays are
allowed to complete normally until after scsi_remove_host() returns.
This means that the commands needed for an orderly shutdown will be
sent through to the device.
Unlike before, the driver will now execute every command that it
accepts. Hence there's no need for special code to catch unexecuted
commands and fail them.
The new sequence of events when disconnect runs goes as follows:
If the device is truly unplugged, set the DISCONNECTING
flag so we won't try to access it any more.
If the SCSI-scanning thread hasn't started up yet, prevent
it from doing anything by setting the new DONT_SCAN flag.
Then wake it up and wait for it to terminate.
Remove the SCSI host. This unbinds the upper-level drivers,
doing an orderly shutdown. Commands sent to quiesce the
device will be transmitted normally, unless the device is
unplugged.
Set the DISCONNECTING flag so that we won't accept any new
commands that might get submitted (there aren't supposed to be
any) and we won't try to access the device for resets.
Tell the control thread to exit by waking it up with no
pending command, and wait for it to terminate.
Go on to do all the other normal stuff: releasing resources,
freeing memory, and so on.

USB: implement "soft" unbinding
This patch (as1091) changes the way usbcore handles interface
unbinding. If the interface's driver supports "soft" unbinding (a new
flag in the driver structure) then in-flight URBs are not cancelled
and endpoints are not disabled. Instead the driver is allowed to
continue communicating with the device (although of course it should
stop before its disconnect routine returns).
The purpose of this change is to allow drivers to do a clean shutdown
when they get unbound from a device that is still plugged in. Killing
all the URBs and disabling the endpoints before calling the driver's
disconnect method doesn't give the driver any control over what
happens, and it can leave devices in indeterminate states. For
example, when usb-storage unbinds it doesn't want to stop while in the
middle of transmitting a SCSI command.
The soft_unbind flag is added because in the past, a number of drivers
have experienced problems related to ongoing I/O after their disconnect
routine returned. Hence "soft" unbinding is made available only to
drivers that claim to support it.
The patch also replaces "interface_to_usbdev(intf)" with "udev" in a
couple of places, a minor simplification.

If this wasn't sufficient then khubd will debounce any port that still

netfilter: accounting rework: ct_extend + 64bit counters (v4)
Initially netfilter has had 64bit counters for conntrack-based accounting, but
it was changed in 2.6.14 to save memory. Unfortunately in-kernel 64bit counters are
still required, for example for "connbytes" extension. However, 64bit counters
waste a lot of memory and it was not possible to enable/disable it runtime.
This patch:
- reimplements accounting with respect to the extension infrastructure,
- makes one global version of seq_print_acct() instead of two seq_print_counters(),
- makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n),
- makes it possible to enable/disable it at runtime by sysctl or sysfs,
- extends counters from 32bit to 64bit,
- renames ip_conntrack_counter -> nf_conn_counter,
- enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT),
- set initial accounting enable state based on CONFIG_NF_CT_ACCT
- removes buggy IPCT_COUNTER_FILLING event handling.
If accounting is enabled newly created connections get additional acct extend.
Old connections are not changed as it is not possible to add a ct_extend area
to confirmed conntrack. Accounting is performed for all connections with
acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".

Since the driver is using phylib (which is doing netif_carrier_on/off()),
we should simply remove netif_tx_schedule_all() from adjust_link().

atl1: Do not wake queue before queue has been started.
Based upon a bug report by Alexey Dobriyan, the patch is
also tested by him and confirmed to fix the problem.
Packet flow during link state events should not be done by
waking and stopping the TX queue anyways, that is handled
transparently by netif_carrier_{on,off}().
So, remove the netif_{wake,stop}_queue() calls in the link
check code, and add the necessary netif_start_queue() call
to atl1_up().
