ipvs: Create init functions for estimator code
Commit
8ab19ea36c5c5340ff598e4d15fc084eb65671dc ("ipvs: Fix possible deadlock
in estimator code") fixed a deadlock condition, but that condition can only
happen during unload of IPVS, because during normal operation there is at least
our global stats structure in the estimator list. The mod_timer() and
del_timer_sync() calls are actually initialization and cleanup code in
disguise. Let's make it explicit and move them to their own init and cleanup
function.

ipvs: Only call init_service, update_service and done_service for schedulers if defined
There are schedulers that only schedule based on data available in the service
or destination structures and they don't need any persistent storage or
initialization routine. These schedulers currently provide dummy functions for
the init_service, update_service and/or done_service functions. For the
init_service and done_service cases we already have code that only calls these
functions, if the scheduler provides them. Do the same for the update_service
case and remove the dummy functions from all schedulers.

USB: serial gadget: rx path data loss fixes
Update RX path handling in new serial gadget code to cope better with
RX blockage: queue every RX packet until its contents can safely be
passed up to the ldisc. Most of the RX path work is now done in the
RX tasklet, instead of just the final "push to ldisc" step. This
addresses some cases of data loss:
- A longstanding serial gadget bug: when tty_insert_flip_string()
didn't copy the entire buffer, the rest of the characters were
dropped! Now that packet stays queued until the rest of its data
is pushed to the ldisc.
- Another longstanding issue: in the unlikely case that an RX
transfer returns data and also reports a fault, that data is
no longer discarded.
- In the recently added RX throttling logic: it needs to stop
pushing data into the TTY layer, instead of just not submitting
new USB read requests. When the TTY is throttled long enough,
backpressure will eventually make the OUT endpoint NAK.
Also: an #ifdef is removed (no longer necessary); and start switching
to a better convention for debug messages (prefix them with tty name).

USB: fix USB boot crash, ecm_do_notify(), list_add corruption. prev->next should be next (
ffff88003b8f82f8)
This fixes a BUG() turned up by Ingo via randconfig testing, where
CONFIG_LIST_DEBUG turned up list corruption. The corruption was
caused by the dummy_hcd (single-machine test harness for gadget and
HCD code) trashing the request queue when driven by the new CDC
composite gadget an I/O pattern that was previously uncommon.
Fix suggested by Alan Stern.

usb: auerswald: remove driver (obsolete)
This patch removes the auerswald USB driver from the linux kernel
2.6.26.
This driver was included into the kernel mainly to connect to the ISDN
framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile
and moving ISDN support, this connection was never realized, and the
only use of this driver was for device configuration. In the age of DSL,
the demand of ISDN support is getting very low.
Meanwhile, with the advent of libusb, an userspace driver was done for
the device configuration which works fine for linux and mac. (Thanks to
the libusb developers!). The userspace driver is downloadable from the
auerswald web site.
So this driver is obsolete now and has to be removed. Many thanks to all
developers which helped me to bring this driver up and working.

Also, remove unused variable in save_stack_trace().

CRED: Introduce credential access wrappers
The patches that are intended to introduce copy-on-write credentials for 2.6.28
require abstraction of access to some fields of the task structure,
particularly for the case of one task accessing another's credentials where RCU
will have to be observed.
Introduced here are trivial no-op versions of the desired accessors for current
and other tasks so that other subsystems can start to be converted over more
easily.
Wrappers are introduced into a new header (linux/cred.h) for UID/GID,
EUID/EGID, SUID/SGID, FSUID/FSGID, cap_effective and current's subscribed
user_struct. These wrappers are macros because the ordering between header
files mitigates against making them inline functions.
linux/cred.h is #included from linux/sched.h.
Further, XFS is modified such that it no longer defines and uses parameterised
versions of current_fs[ug]id(), thus getting rid of the namespace collision
otherwise incurred.

netns: Fix crash by making igmp per namespace
This patch makes the multicast socket to be per namespace.
When a network namespace is created, other than the init_net and a
multicast packet is received, the kernel goes to a hang or a kernel panic.
How to reproduce ?
* create a child network namespace
* create a pair virtual device veth
* ip link add type veth
* move one side to the pair network device to the child namespace
* ip link set netns <childpid> dev veth1
* ping -I veth0 224.0.0.1
The bug appears because the function ip_mc_init_dev does not initialize
the different multicast fields as it exits because it is not the init_net.
