Registering the card as a wakeup source needs to be done once, during initialization.

2015-02-03mwifiex: disable UAPSD mode when AP startsAmitkumar Karwar
When AP is started, firmware exits power save mode. This means power save manager of AP takes priority over station. Firmware stop sending periodic AWAKE events to host. We may have UAPSD enabled on station which buffers data packets until AWAKE event from firmware. Data path is unnecessarily blocked in this case. This patch disables UAPSD mode to reenable transmit data path.

2015-02-03ARM: 8299/1: mm: ensure local active ASID is marked as allocated on rolloverWill Deacon
Commit e1a5848e3398 ("ARM: 7924/1: mm: don't bother with reserved ttbr0 when running with LPAE") removed the use of the reserved TTBR0 value for LPAE systems, since the ASID is held in the TTBR and can be updated atomicly with the pgd of the next mm. Unfortunately, this patch forgot to update flush_context, which deliberately avoids marking the local active ASID as allocated, since we used to switch via ASID zero and didn't need to allocate the ASID of the previous mm. The side-effect of this is that we can allocate the same ASID to the next mm and, between flushing the local TLB and updating TTBR0, we can perform speculative TLB fills for userspace nG mappings using the page table of the previous mm. The consequence of this is that the next mm can erroneously hit some mappings of the previous mm. Note that this was made significantly harder to hit by a391263cd84e ("ARM: 8203/1: mm: try to re-use old ASID assignments following a rollover") but is still theoretically possible. This patch fixes the problem by removing the code from flush_context that forces the allocated ASID to zero for the local CPU. Many thanks to the Broadcom guys for tracking this one down.

The function raid5_quiesce() (and resize_stripes()) uses the 'cmd' part to release and acquire a spinlock (so we call the sleep primitives in atomic context), and therefore we cannot do the might_sleep() check.

2015-02-02net: sctp: Deletion of an unnecessary check before the function call "kfree"Markus Elfring
The kfree() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
