This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.The microcode_core.c patch was provided by Stephen Rothwell
who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.Signed-off-by: Greg Kroah-Hartman

On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself. Elsewhere, operations including
memcpy and kfree are performed on the country_code field. The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.Signed-off-by: Julia Lawall

The ACM_READY() macro doesn't seem to do anything useful, and it may
prevent tty_wait_until_sent() from working properly when called from
close.Previously, acm_tty_chars_in_buffer() returned 0 whenever
acm->port.count was 0. This means close() could return before all the
data has actually been written.Signed-off-by: Havard Skinnemoen

Rework the locking and lifecycle management in the cdc-acm driver.
Instead of using a global mutex to prevent the 'acm' object from being
freed, use the tty_port kref to keep the device alive when either the
USB side or TTY side is still active.This allows us to use the global mutex purely for protecting the
acm_table, while use acm->mutex to guard against disconnect during
TTY port activation and shutdown.The USB-side kref is taken during port initialization in probe(), and
released at the end of disconnect(). The TTY-side kref is taken in
install() and released in cleanup(). On disconnect, tty_vhangup() is
called instead of tty_hangup() to ensure the TTY hangup processing is
completed before the USB device is taken down.The TTY open and close handlers have been gutted and replaced with
tty_port_open() and tty_port_close() respectively. The driver-specific
code which used to be there was spread across install(), activate() and
shutdown().Reported-by: Dave Jones

There's a race between the USB disconnect handler and the TTY close
handler which may cause the acm object to be freed while it's still
being used. This may lead to things likehttp://article.gmane.org/gmane.linux.usb.general/54250
and
https://lkml.org/lkml/2011/5/29/64
This is the simplest fix I could come up with. Holding on to open_mutex
while closing the TTY device prevents acm_disconnect() from freeing the
acm object between acm->port.count drops to 0 and the TTY side of the
cleanups are finalized.Signed-off-by: Havard Skinnemoen

Prevent read urbs from being resubmitted from tasklet after port close.
The receive tasklet was not disabled on port close, which could lead to
corruption of receive lists on consecutive port open. In particular,
read urbs could be re-submitted before port open, added to free list in
open, and then added a second time to the free list in the completion
handler.cdc-acm.c: Entering acm_tty_open.

In the WDM class driver a disconnect event leads to calls to
usb_free_coherent to put back two USB DMA buffers allocated earlier.
The call to usb_free_coherent uses a different size parameter
(desc->wMaxCommand) than the corresponding call to usb_alloc_coherent
(desc->bMaxPacketSize0).When a disconnect event occurs, this leads to 'bad dma' complaints
from usb core because the USB DMA buffer is being pushed back to the
'buffer-2048' pool from which it has not been allocated.This patch against the most recent linux-2.6 kernel ensures that the
parameters used by usb_alloc_coherent & usb_free_coherent calls in
cdc-wdm.c match.Signed-off-by: Robert Lukassen

Only oddities here are a couple of drivers that bogusly called the ldisc
helpers instead of returning -ENOIOCTLCMD. Fix the bug and the rest goes
