2013-09-26ath9k: replace snprintf() with scnprintf()Zefir Kurtisi
Whenever the return value of snprintf() is used to calculate remaining buffer-space, we wanted to use sncprintf() instead. Indentation is adapted where possible. Some lines exceed the line width limit, either they did it already before, or since they can not be broken reasonably well.

2013-09-26bcma: make bcma_core_pci_{up,down}() callable from atomic contextArend van Spriel
This patch removes the bcma_core_pci_power_save() call from the bcma_core_pci_{up,down}() functions as it tries to schedule thus requiring to call them from non-atomic context. The function bcma_core_pci_power_save() is now exported so the calling module can explicitly use it in non-atomic context. This fixes the 'scheduling while atomic' issue reported by Tod Jackson and Joe Perches.

2013-09-26brcmfmac: obtain platform data upon module initializationArend van Spriel
The driver uses platform_driver_probe() to obtain platform data if any. However, that function is placed in the .init section so it must be called upon driver module initialization. The problem was reported by Fenguang Wu resulting in a kernel oops because the .init section was already freed.

Bug 60815 - Interface hangs in mwifiex_usb https://bugzilla.kernel.org/show_bug.cgi?id=60815 We have 4 bytes of interface header for packets delivered to SDIO and PCIe, but not for USB interface. In Tx AMSDU case, currently 4 bytes of garbage data is unnecessarily appended for USB packets. This sometimes leads to a firmware hang, because it may not interpret the data packet correctly. Problem is fixed by removing this redundant headroom for USB.

2013-09-26mwifiex: fix PCIe hs_cfg cancel cmd timeoutBing Zhao
For pcie8897, the hs_cfg cancel command (0xe5) times out when host comes out of suspend. This is caused by an incompleted host sleep handshake between driver and firmware. Like SDIO interface, PCIe also needs to go through firmware power save events to complete the handshake for host sleep configuration. Only USB interface doesn't require power save events for hs_cfg.

2013-09-26net: neighbour: use source address of last enqueued packet for solicitationHannes Frederic Sowa
Currently we always use the first member of the arp_queue to determine the sender ip address of the arp packet (or in case of IPv6 - source address of the ndisc packet). This skb is fixed as long as the queue is not drained by a complete purge because of a timeout or by a successful response. If the first packet enqueued on the arp_queue is from a local application with a manually set source address and the to be discovered system does some kind of uRPF checks on the source address in the arp packet the resolving process hangs until a timeout and restarts. This hurts communication with the participating network node. This could be mitigated a bit if we use the latest enqueued skb's source address for the resolving process, which is not as static as the arp_queue's head. This change of the source address could result in better recovery of a failed solicitation. Cc: "David S.

2013-09-26xfs: fix node forward in xfs_node_toosmallMark Tinguely
Commit f5ea1100 cleans up the disk to host conversions for node directory entries, but because a variable is reused in xfs_node_toosmall() the next node is not correctly found. If the original node is small enough (<= 3/8 of the node size), this change may incorrectly cause a node collapse when it should not. That will cause an assert in xfstest generic/319: Assertion failed: first <= last && last < BBTOB(bp->b_length), file: /root/newest/xfs/fs/xfs/xfs_trans_buf.c, line: 569 Keep the original node header to get the correct forward node. (When a node is considered for a merge with a sibling, it overwrites the sibling pointers of the original incore nodehdr with the sibling's pointers. This leads to loop considering the original node as a merge candidate with itself in the second pass, and so it incorrectly determines a merge should occur.)
