Some network interfaces of the wireless drivers lack the 'device'
symlink in sysfs.
This patch lets the drivers create the links.

This is a fix for OLPC ticket #6586: "SCAN command fails, timer doesn't
fire". In fact, the timer was firing; the problem was that the dnld_sent
state variable was not being updated after the timer expired, so
lbs_execute_next_command was not being called.

A user reported seeing occasional bugs such as the following when
using the L2TP driver.
SKB BUG: Invalid truesize (272) len=72, sizeof(sk_buff)=208
When L2TP adds its header in the transmit path, it might need to
increase the headroom of the skb. In some cases, the increased
headroom trips a kernel bug when the skb is freed because the skb has
grown beyond its truesize value. The fix is to increase the truesize
by the amount of headroom added, after orphaning the skb.
While here, fix a misleading comment.
Thanks to Iouri Kharon <bc-info@styx.cabel.net> for the initial
report and testing the fix.

The use of cli()/sti() within the do/while was a way to ensure
interrupts were only disabled for short periods of time while the bulk
of the time interrupts were free to occur. The use of the spin lock
has eliminated the need to play with interrupts in this way while
still allowing for IO to be protected.
The remaining 3 sti() calls seem unneeded now that at no other point
in the driver is there a call to cli().

It is possible that the entry in sysfs already exists, one case of this is
when a network device is renamed to bonding_masters. Anyway, in this case
the proper error path is for device_rename to return an error code, not to
generate bogus backtrace and errors.
Also, to avoid possible races, the create link should be done before the
remove link. This makes a device rename atomic operation like other renames.

When a cpu really is stuck in the kernel, it can be often
impossible to figure out which cpu is stuck where. The
worst case is when the stuck cpu has interrupts disabled.
Therefore, implement a global cpu state capture that uses
SMP message interrupts which are not disabled by the
normal IRQ enable/disable APIs of the kernel.
As long as we can get a sysrq 'y' to the kernel, we can
get a dump. Even if the console interrupt cpu is wedged,
we can trigger it from userspace using /proc/sysrq-trigger
The output is made compact so that this facility is more
useful on high cpu count systems, which is where this
facility will likely find itself the most useful :)

Commit 7329e211b987a493cbcfca0e98c60eb108ab42df ("USB: root hubs don't
lie about their number of TTs") requires the various platform EHCI
glue modules to set ->has_tt if the root hub has a Transaction
Translator.
The Orion EHCI root hub does have a Transaction Translator, so set
->has_tt in ehci_orion_setup(). This fixes oopsing on plugging in a
low speed device.

We want to have the drvdata field set properly when creating the device
as sysfs callbacks can assume it is present and it can race the later
setting of this field.
So, create two new functions, deviec_create_vargs() and
device_create_drvdata() that take this new field.
device_create_drvdata() will go away in 2.6.27 as the drvdata field will
just be moved to the device_create() call as it should be.

1) Remove an explicit memset(.., 0, ...) to a variable allocated with
kzalloc (i.e. 'dest').
2) Allocate 'src' with kmalloc instead of kzalloc as all elements of the
'src' buffer are initialized in a 'for(...)' loop just after.
3) remove useless 'sizeof(u8)', which always returns 1, when computing the
size of the memory to be allocated.

firewire: prevent userspace from accessing shut down devices
ieee1394: sbp2: use correct size of command descriptor block

If userspace ignores the POLLERR bit from poll(), and only attempts to
read() the device when POLLIN is set, it can still make ioctl() calls on
a device that has been removed from the system. The node_id and
generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET
would still cause a bus reset, and GET_CYCLE_TIMER will return data.
And if you guess the correct generation to use, you can send requests to
a different device on the bus, and get responses back.
This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown
devices.

vidiocgmbuf() does this:
mutex_lock(&fh->cap.vb_lock);
retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize,
V4L2_MEMORY_MMAP);
and videobuf_mmap_setup() then just does
mutex_lock(&q->vb_lock);
ret = __videobuf_mmap_setup(q, bcount, bsize, memory);
mutex_unlock(&q->vb_lock);
which is an obvious double-take deadlock.
This patch fixes this by having vidiocgmbuf() just call the
__videobuf_mmap_setup function instead.

Microchip PICkit 1 and PICKit 2 USB Programmers are USB HID class of device but
they are not real HID device. They are now supported by libusb based programs
like the following programs.
pk2 and pk2cmd Linux port:
http://home.pacbell.net/theposts/picmicro/
usb_pickit:
http://tfc.duke.free.fr/pickit.html
usb_pickit original version:
http://charm.cs.uiuc.edu/users/olawlor/projects/2003/microchip/
Therefore it ispreferred to blacklist them.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.
This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.
If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.
Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.
