2013-08-16iwlwifi: mvm: Implement CQM offloadingAndrei Otcheretianski
Use beacon statistics notification to track RSSI. Notify mac80211 when the tresholds are crossed. The roaming treshold is configured to be equal to cqm_thold. If the beacon filtering command is not supported by fw fall back and use mac80211 mechanism.

2013-08-16iwlwifi: return -ENOMEM instead of NULL when OOM in iwl_drv_start()Luciano Coelho
The callers of iwl_drv_start() are probe functions. If a probe function returns 0, it means it succeeded. So if NULL was returned by iwl_drv_start(), it would be considered as a success. Fix this by returning -ENOMEM if the driver struct allocation fails in iwl_drv_start(). Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-08-16iwlwifi: mvm: refactor resume from WoWLAN codeJohannes Berg
To be able to add more logic to the resume code, refactor it a bit, moving some status checking/reporting logic into a new function. The locking becomes a bit odd (one of the new functions now unlocks the mutex) but this will be required to call new mac80211 APIs in there later.

2013-08-16xfrm: Make xfrm_state timer monotonicFan Du
xfrm_state timer should be independent of system clock change, so switch to CLOCK_BOOTTIME base which is not only monotonic but also counting suspend time. Thus issue reported in commit: 9e0d57fd6dad37d72a3ca6db00ca8c76f2215454 ("xfrm: SAD entries do not expire correctly after suspend-resume") could ALSO be avoided. v2: Use CLOCK_BOOTTIME to count suspend time, but still monotonic.

2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

NFSv4 reserves readdir cookie values 0-2 for special entries (. and ..), but jfs allows a value of 2 for a non-special entry.

2013-08-15ath9k_htc: do not use bulk on EP3 and EP4Oleksij Rempel
If usb auto suspend is enabled or system run in to suspend/resume cycle, ath9k-htc adapter will stop to response. It is reproducible on xhci HCs. Host part of problem: XHCI do timing calculation based on Transfer Type and bInterval, immediately after device was detected. Ath9k-htc try to overwrite this parameters on module probe and some changes in FW, since we do not initiate usb reset from the driver this changes are not took to account. So, before any kind of suspend or reset, host controller will operate with old parameters. Only after suspend/resume and if interface id stay unchanged, new parameters will by applied. Host will send bulk data with no intervals (?), which will cause overflow on FIFO of EP4. Firmware part of problem: By default, ath9k-htc adapters configured with EP3 and EP4 as interrupt endpoints. Current firmware will try to overwrite ConfigDescriptor to make EP3 and EP4 bulk. FIFO for this endpoints stay not reconfigured, so under the hood it is still Int EP. This patch is revert of 4a0e8ecca4ee commit which trying to reduce CPU usage on some systems. Since it will produce more bug as fixes, we will need to find other way to fix it. here is comment from kernel source which has some more explanation: * Some buggy high speed devices have bulk endpoints using * maxpacket sizes other than 512. High speed HCDs may not * be able to handle that particular bug, so let's warn... in our case EP3 and EP4 have maxpacket sizes = 64!!!
