As the services directory is going to be removed, the cfg_set_object
function has also to be removed.
Since the driver object handle is retrieved from the drv_data structure,
then the word "Registry" is replaced by "driver data" in the comments.

As the services directory is going to be removed, the cfg_get_exec_file
function has also to be removed.
This patch also avoids a possible NULL pointer dereference in function
cfg_get_exec_file(), when drv_datap is checked for NULL and then pass
drv_datap->base_img as argument to strlen().

The cfg_get_dev_object function is only used in one place and because of
its simplicity, it can be removed.
The parameter *value can be left uninitialized if the strcmp() returns a
nonzero value, so in the function dev_remove_device(), the hdev_obj could
be used uninitialized and could be dereferenced in dev_destroy_device().
This patch fixes this issue, and also removes the dev_obj pointer which
is not used.

As the services directory is going to be removed, this patch is needed.
The function cfg_get_auto_start() only assigns a value to the flag
tmp, and it is only called by the function api_init_complete2(). So
the function cfg_get_auto_start() is not required.

This is a driver for SBE Inc.'s dual port T3/E3 WAN cards. Based on
their original GPLed driver.
The original driver tarball is now accessible at
http://userweb.kernel.org/~chris/SBE_2T3_Linux_2.0c.tgz
It needs at least a new generic HDLC setup code (not yet written) before
moving to drivers/net/wan.

This is a driver for the Cypress West Bridge companion chip. Its
function is analogous to the North/South Bridges of PC environments
applied to embedded devices, in that it expands I/O and storage
capabilities of an embedded processor. The Astoria version, which this
driver applies to, functions as a USB, embedded memory and SDIO
controller. The kernel that this patch was applied to is linux-2.6.35,
although it was tested using the android kernel 2.6.29 running on the
Zoom 2 platform. In this system, it was used primarily as a sideloading
accelerator enabling direct data transfers between a USB host PC and
embedded memory without system overheads. Minor modifications were also
made to the kernel for this patch. These include changes such as
EXPORTing of fat_get_block in the kernel code. Another function,
mpage_cleardirty was also added to the memory management code. This
function is used to clear the dirty pages from a specific inode. This
allows for direct, file based DMA. None of these changes are believed to
have any negative impact on the kernel and may provide additional
benefit for other developers and drivers.
The driver, as submitted, was placed into the drivers/staging/westbridge
folder as the directory structure it will eventually reside in is not yet
defined. The driver, as placed in staging is divided into four parts:
1) gadget - this implements a gadget peripheral controller and includes IOCTLs
for MTP transfers
2) block -this implements a generic block device driver to enable access to
embedded memory
3) api -this is the Cypress SDK, and includes USB and Storage specific
functions. In addition, it includes common code for low level routines such as
message passing and common data transfer routines
4) hal - this should likely be included in the arch directory as it needs to
be modified for a given platform. The directory structure in the staging area
is meant to reflect the eventual location of where this code likely should be.
It is platform specific. In this case, the HAL included is for the Android
Zoom 2 platform. Here, West Bridge is connected to the GPMC (general purpose
memory controller) of the OMAP3. Specific timing needs to be enabled to ensure
reliable communication.
Many thanks to Greg KH for conducting initial reviews and providing pointers.

Each net_device in a system will automatically managed as a possible
batman_if and holds different informations like a buffer with a prepared
originator messages. To reduce the memory usage, the packet_buff will
only be allocated when the interface is really added/enabled for
batman-adv.
The function to update the hw address information inside the packet_buff
just assumes that the packet_buff is always initialised and thus the
kernel will just oops when we try to change the hw address of a not
already fully enabled interface.
We must always check if the packet_buff is allocated before we try to
change information inside of it.

dev_put allows a device to be freed when all its references are dropped.
After that we are not allowed to access that information anymore. Access
to the data structure of a net_device must be surrounded a dev_hold
and ended using dev_put.
batman-adv adds a device to its own management structure in
hardif_add_interface and will release it in hardif_remove_interface.
Thus it must hold a reference all the time between those functions to
prevent any access to the already released net_device structure.

We try to get all events for all net_devices to be able to add special
sysfs folders for the batman-adv configuration. This also includes such
events like NETDEV_POST_INIT which has no valid kobject according to
v2.6.32-rc3-13-g7ffbe3f. This would create an oops in that situation.
It is enough to create the batman_if only on NETDEV_REGISTER events
because we will also receive those events for devices which already
existed when we registered the notifier call.

When receiving an batman icmp echo request or in case of a time-to-live
exceeded batman would reply with the mac address of the outgoing
interface which might be a secondary interface. Because secondary
interfaces are not globally known this might lead to confusion.

If a batman icmp packet had to be routed over a secondary interface
at the first hop, the mac address of that secondary interface would
be written in the 'orig' field of the icmp packet. A node which is
more than one hop away is not aware of the mac address because
secondary interfaces are not flooded through the whole mesh and
therefore can't send a reply.
This patch always sends the mac address of the primary interface
in the 'orig' field of the icmp packet.

fs: fs_struct rwlock to spinlock
struct fs_struct.lock is an rwlock with the read-side used to protect root and
pwd members while taking references to them. Taking a reference to a path
typically requires just 2 atomic ops, so the critical section is very small.
Parallel read-side operations would have cacheline contention on the lock, the
dentry, and the vfsmount cachelines, so the rwlock is unlikely to ever give a
real parallelism increase.
Replace it with a spinlock to avoid one or two atomic operations in typical
path lookup fastpath.

sysfs-writable charp arguments need to be locked against modification
(since the old ones may be kfreed underneath us). String arguments
are much simpler, so use them for small strings (eg. IFNAMSIZ).
lkdtm only uses the parameters at module initialization time, so there's
not much point making them writable.

This patch (as1393) converts several of the single-bit fields in
struct usb_hcd to atomic flags. This is for safety's sake; not all
CPUs can update bitfield values atomically, and these flags are used
in multiple contexts.
The flag fields that are set only during registration or removal can
remain as they are, since non-atomic accesses at those times will not
cause any problems.
(Strictly speaking, the authorized_default flag should become atomic
as well. I didn't bother with it because it gets changed only via
sysfs. It can be done later, if anyone wants.)
