Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue,
and remove all the orignal tangled-up code. Update the documentation
accordingly. This is a net object code shrink and cleanup; it should
make it a lot easier to see how the TTY glue should accomodate updates
to the TTY layer, be bugfixed, etc.
Notable behavior changes include: it can now support getty even when
there's no USB connection; it fits properly into the mdev/udev world;
and RX handling is better (throttling works, and low latency).
Configurations with scripts setting up the /dev/ttygserial device node
(with "experimental" major number) may want to change that to be a
symlink pointing to the /dev/ttyGS0 file, as a migration aid; else,
just switch entirely over to mdev/udev.

This abstracts the "gadget serial" driver TTY glue into a separate
component, cleaning it up and disentangling it from connection state.
It also changed some behaviors for the better:
- Stops using "experimental" major #127, and switches over to
having the TTY layer allocate the dev_t numbers.
- 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
adapters, since it eliminates scheduler overhead on RX paths.
This also includes much cleanup including better comments, fixing
memory leaks and other bugs (including some locking fixes), messaging
cleanup, and an interface audit and tightening. This added up to a
significant object code shrinkage, on the order of 20% (!) depending
on CPU and compiler.
A separate patch actually kicks in this new code, using the functions
declared in this new header, and removes the previous glue.

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.

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.

This patch (as1089) separates out the dynamic atomic bitflags and the
static bitfields in usb-storage. Until now the two sorts of flags
have been sharing the same word; this has always been awkward.
To help prevent possible confusion, the two new fields each have a
different name from the original. us->fflags contains the fixed
bitfields (mostly taken from the USB ID table in unusual_devs.h), and
us->dflags contains the dynamic atomic bitflags (used with set_bit,
test_bit, and so on).

This patch (as1082) makes a small optimization to the way the hub
driver carries out port debouncing immediately after a hub is
activated (i.e., initialized, reset, or resumed). If any port-change
statuses are observed, the code will delay for a minimal debounce
period -- thereby making a good start at debouncing all the ports at
once.
If this wasn't sufficient then khubd will debounce any port that still
requires attention. But in most cases it should suffice; it's rare
for a device to need more than a minimal debounce delay. (In the
cases of hub initialization or reset even that is most likely not
needed, since any devices plugged in at such times have probably been
attached for a while.)

This patch (as1073) adds to khubd a way to recover from power-session
interruption caused by transient connect-change or enable-change
events. After the debouncing period, khubd attempts to do a
USB-Persist-style reset or reset-resume. If it works, the connection
will remain unscathed.
The upshot is that we will be more immune to noise caused by EMI. The
grace period is on the order of 100 ms, so this won't permit recovery
from the "accidentally knocked the USB cable out of its socket" type
of event, but it's a start.
As an added bonus, if a device was suspended when the system goes to
sleep then we no longer need to check for power-session interruptions
when the system wakes up. Khubd will naturally see the status change
while processing the device's parent hub and will do the right thing.
The remote_wakeup() routine is changed; now it expects the caller to
acquire the device lock rather than acquiring the lock itself.

This patch (as1081) straightens out the logic of the hub_restart()
routine. Each port of the hub is scanned and the driver makes sure
that ports which are supposed to be disabled really _are_ disabled.
Any ports with a significant change in status are flagged in
hub->change_bits, so that khubd can focus on them without the need to
scan all the ports a second time -- which means the hub->activating
flag is no longer needed.
Also, it is now recognized explicitly that the only reason for
resuming a port which was not suspended is to carry out a reset-resume
operation, which happens only in a non-CONFIG_USB_SUSPEND setting.

This patch (as1080) makes a significant change to the way khubd
handles port connect-change and enable-change events. Both types of
event are now debounced, and the debouncing is carried out _before_ an
existing usb_device is unregistered, instead of afterward.
This means that drivers will have to deal with longer runs of errors
when a device is unplugged, but they are supposed to be prepared for
that in any case.
The advantage is that when an enable-change occurs (caused for example
by electromagnetic interference), the debouncing period will provide
time for the cause of the problem to die away. A simple port reset
(added in a forthcoming patch) will then allow us to recover from the
fault.

This patch (as1070) creates a new subroutine to check whether a device
can be resumed. This code is needed even when CONFIG_USB_SUSPEND
isn't set, because devices do suspend themselves when the root hub
(and hence the entire bus) is suspended, and power sessions can get
lost during a system sleep even without individual port suspends.
The patch also fixes a loose end in USB-Persist reset-resume handling.
When a low- or full-speed device is attached to an EHCI's companion
controller, the port handoff during resume will cause the companion
port's connect-status-change feature to be set. If that flag isn't
cleared, the port-reset code will think it indicates that the device
has been unplugged and the reset-resume will fail.

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".

2) Makes hash less attackable by using random seed.
3) Eliminates endianness hash distribution issues.

Based upon a bug report by Alexander Beregalov and commentary
from Ben Hutchings.
These are totally unnecessary, in particular because this
driver's ->hard_start_xmit() handler takes the same driver
spinlock that the set-multicast-list handler uses.

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