2013-06-24cw1200: Fix up a large pile of sparse warningsSolomon Peachy
Most of these relate to endianness problems, and are purely cosmetic. But a couple of them were legit -- listen interval parsing and some of the rate selection code would malfunction on BE systems. There's still one cosmetic warning remaining, in the (admittedly) ugly code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI transfers, but many SPI controllers only operate 8 bits at a time. If there's a cleaner way of handling this, I'm all ears.

2013-06-24ath9k: fix queue depth accounting in ath_tx_txqaddbufFelix Fietkau
ath_tx_txqaddbuf assumes that all the linked buffers in the queue passed to it are part of the same A-MPDU or MPDU. The CAB queue rework violates this assumption, which can cause the internal queue depth to go negative.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-17mwifiex: fix memory corruption when unsetting multicast listDaniel Drake
When trying to unset a previously-set multicast list (i.e. the new list has 0 entries), mwifiex_set_multicast_list() was calling down to mwifiex_request_set_multicast_list() while leaving mcast_list.num_multicast_addr as an uninitialized value. We were arriving at mwifiex_cmd_mac_multicast_adr() which would then proceed to do an often huge memcpy of mcast_list.num_multicast_addr*ETH_ALEN bytes, causing memory corruption and hard to debug crashes. Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast list is provided. Similarly, fix up the logic in mwifiex_request_set_multicast_list() to unset the multicast list that was previously sent to the hardware in such cases.
