2012-05-15NFC: Select CRC_CCITT for SHDLC link layer of HCI based driversMarcel Holtmann
The SHDLC link layer of HCI based drivers uses CRC-CCITT and thus needs to select that kernel option. Otherwise it ends up with this linking error: net/built-in.o: In function `nfc_shdlc_add_len_crc': net/nfc/hci/shdlc.c:113: undefined reference to `crc_ccitt' Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.

2012-05-15mac80211_hwsim: Fix rate control by correctly reporting transmission countsJavier Cardona
Drivers need to report the number of transmission attempts for each rate as well as to terminate the rate array with -1. The in-kernel datapath of hwsim simulates a perfect medium, therefore the driver only needs to report that the first transmission attempt was sucessfully completed at the most favorable rate. Rate control is working again for this driver. Tested mesh mode with minstrel. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-05-15sparc32: Kill off software 32-bit multiply/divide routines.David S. Miller
For the explicit calls to .udiv/.umul in assembler, I made a mechanical (read as: safe) transformation. I didn't attempt to make any simplifications. In particular, __ndelay and __udelay can be simplified significantly. Some of the %y reads are unnecessary and these routines have no need any longer for allocating a register window, they can be leaf functions. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-15net: Add net_ratelimited_function and net_<level>_ratelimited macrosJoe Perches
__ratelimit() can be considered an inverted bool test because it returns true when not ratelimited. Several tests in the kernel tree use this __ratelimit() function incorrectly. No net_ratelimit uses are incorrect currently though. Most uses of net_ratelimit are to log something via printk or pr_<level>. In order to minimize the uses of net_ratelimit, and to start standardizing the code style used for __ratelimit() and net_ratelimit(), add a net_ratelimited_function() macro and net_<level>_ratelimited() logging macros similar to pr_<level>_ratelimited that use the global net_ratelimit instead of a static per call site "struct ratelimit_state".

2012-05-15usbnet: fix skb traversing races during unlink(v2)Ming Lei
Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock before unlink, but may cause skb traversing races: - after URB is unlinked and the queue lock is released, the refered skb and skb->next may be moved to done queue, even be released - in skb_queue_walk_safe, the next skb is still obtained by next pointer of the last skb - so maybe trigger oops or other problems This patch extends the usage of entry->state to describe 'start_unlink' state, so always holding the queue(rx/tx) lock to change the state if the referd skb is in rx or tx queue because we need to know if the refered urb has been started unlinking in unlink_urbs. The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.
