73ac36ea14 fix similar typos to successfull
When I review ocfs2 code, find there are 2 typos to "successfull".  After
doing grep "successfull " in kernel tree, 22 typos found totally -- great
minds always think alike :)

This patch fixes all the similar typos. Thanks for Randy's ack and comments.

f201a8a451 drivers/net/usb: use USB API functions rather than constants
This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

In drivers/net/wireless/zd1211rw/zd_usb.c the code:

(endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT

is suspicious.  If it is intended to use USB_ENDPOINT_DIR_MASK rather than
USB_TYPE_MASK, then the whole conditional test could be converted to a call
to usb_endpoint_is_bulk_in.

An extract of the semantic patch that makes these changes is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r1@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==

@r5@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==

be2864cfff ath9k: Fixed RX decryption status reporting
The RX code in ath9k uses sc_keymap to figure out whether a default
key was used. However, the default key entries in sc_keymap were
always set and as such, frames could have been claimed to be decrypted
by hardware when they were not. This can cause problems especially
with TKIP since mac80211 is validating the Michael MIC in the frame
and this will result in MIC failure and potentially TKIP
countermeasures if the frame was not decrypted correctly.

Change key cache slot allocation to mark only the keys that really
have been used in sc_keymap to avoid the issue. The key cache slot
selection routines are now internally avoiding the slots that may be
needed for TKIP group keys.

f1bc4ac61f iwlwifi: use GFP_KERNEL to allocate Rx SKB memory
Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.

	spin_lock();
	...
	element = rxq->rx_used.next;
	element->skb = alloc_skb(..., GFP_ATOMIC);
	list_del(element);
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).

	spin_lock();
	...
	element = rxq->rx_used.next;
	list_del(element);
	...
	spin_unlock();
	...
	element->skb = alloc_skb(..., GFP_KERNEL);
	...
	spin_lock()
	...
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

This patch should fix the "iwlagn: Can not allocate SKB buffers" warning
we see recently.

d858822733 rtl8187: Fix crash on unload when using SLUB debug
Reported-by: Hin-Tak Leung <htl10@users.sourceforge.net>

After the code was modified to use urb anchors ("rtl8187: Use usb anchor
facilities to manage urbs"), rtl8187 began generating an intermittent GPF
on shutdown when using SLUB with debugging enabled. Furthermore, rebooting
the system with a ping running caused a GPF every time. There are two problems:
(1) incorrect locking in the rtl8187_rx_cb() routine, a pre-existing bug that
apparently had not been triggered before, and (2) duplicate freeing of receive
skbs that was probably introduced with the change to anchors.

da9f57eade rtl8187: Fix error returns
There are two places in the rtl8187 code where a routine was returning zero
(OK) when it should have been returning an error.

54fdb040b4 p54: move statistic timer update routine into a workqueue
This patch moves a good chunk of code from the former statistic update
timer routine into a workqueue, which is kindly provided by mac80211.

Also as a nice side-effect we can lay the foundation for other
essential housekeeping features we want to do in the future.
e.g:
 - drain the (clogged) tx_queue.
 - initiate bursts.

d5e490362f iwlagn: fix agn rate scaling
Rate scaling in agn can be broken because of these two problems
    1- the LQ command could not sent, we try to call LQ command before
       post association will be rejected, this will cause the driver to
       break in rs_tx_status reporting initial rate does not match.
    2- In rs_rate_init we can get a value of 12, rate 60, for
       last_txrate_idx, this rate only valid in SISO/MIMO mode only

0fe45b1deb ath5k: fix 802.11 header padding on RX, unpadding on TX
Padding the 802.11 header to a multiple of 4 bytes needs to be done only for
frames with a body. This fixes a bug where 2 bytes were missing in monitor
mode for ACK frames. Inspired by a patch from Jouni Malinen on ath9k.

baad1d921b ath9k: Report HT rates in RX status
Fix and clean up the RX status reporting by getting rid of code that
used internal rate tables and ratekbps calculation. The correct value
is now reported with MCS index instead of the old mechanism that
defaulted to using the highest legacy rate.

config() callback, the channel type can be calculated whenever
setting the channel. Update the rate table accordingly with the new

094d05dc32 mac80211: Fix HT channel selection
HT management is done differently for AP and STA modes, unify
to just the ->config() callback since HT is fundamentally a
PHY property and cannot be per-BSS.

Rename enum nl80211_sec_chan_offset as nl80211_channel_type to denote
the channel type ( NO_HT, HT20, HT40+, HT40- ).

b88a2a22c6 netdevice zd1201: Use after free
| commit 3d29b0c33d

|     netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv()
|
|     We have some reasons to kill netdev->priv:
|     1. netdev->priv is equal to netdev_priv().
|     2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
|        netdev_priv() is more flexible than netdev->priv.
|     But we cann't kill netdev->priv, because so many drivers reference to it
|     directly.
|
|     OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
|     and I want to kill netdev->priv later, I decided to convert all the direct
|     reference of netdev->priv first.
|
|     (Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
|     changelog but using dev->ml_priv.  That doesn't seem appropriate
|     to me for this driver, so I've revamped it to use netdev_priv()
|     instead. -- JWL)

This commit changed the allocation of netdev, but didn't change
the free method of it.
This causes "zd" be used after the memory, which is pointed by "zd", being
freed by free_netdev().
