2015-11-03net/mlx5e: Avoid NULL pointer access in case of configuration failureAchiad Shochat
In case a configuration operation that involves closing and re-opening resources (e.g RX/TX queue size change) fails at the re-opening stage these resources will remain closed. So when executing (following) configuration operations (e.g ifconfig down) we cannot assume that these resources are available.

2015-11-03xtensa: fix secondary core boot in SMPMax Filippov
There are multiple factors adding to the issue in different configurations: - commit 17290231df16eeee ("xtensa: add fixup for double exception raised in window overflow") added function window_overflow_restore_a0_fixup to double exception vector overlapping reset vector location of secondary processor cores. - on MMUv2 cores RESET_VECTOR1_VADDR may point to uncached kernel memory making code overlapping depend on cache type and size, so that without cache or with WT cache reset vector code overwrites double exception code, making issue even harder to detect. - on MMUv3 cores RESET_VECTOR1_VADDR may point to unmapped area, as MMUv3 cores change virtual address map to match MMUv2 layout, but reset vector virtual address is given for the original MMUv3 mapping. - physical memory region of the secondary reset vector is not reserved in the physical memory map, and thus may be allocated and overwritten at arbitrary moment. Fix it as follows: - move window_overflow_restore_a0_fixup code to .text section. - define RESET_VECTOR1_VADDR so that it points to reset vector in the cacheable MMUv2 map for cores with MMU. - reserve reset vector region in the physical memory map.

Depending on the gcc version we can use builtin_bswap instead of architecture functions. Doing so is better than the inline assembly version of load reverse for two reasons: - the sequence of load reversed, apply constant mask, save reversed can be optimized to load, apply reversed mask, save - builtins are slightly better to optimize e.g. gcc instruction scheduler cannot optimize grouping on inline assemblies.

2015-11-03s390/dasd: fix disconnected device with valid path maskStefan Haberland
Path verification is either done via dasd_eckd_read_conf() which is triggered during online processing and resume or via do_path_verification_work() which is triggered after path events. The dasd_eckd_read_conf() version added paths unconditionally and did not check if the path mask was empty. This led to devices having the disconnected stop flag set but a valid path mask. So they where not working although they had paths validated successfully. After a resume this state could even not be solved with additional paths added. Fix by checking for an empty path mask in dasd_eckd_read_conf() and clearing the device stop bits for a newly added channel path.

2015-11-03s390/dasd: fix invalid PAV assignment after suspend/resumeStefan Haberland

Thus the failing of read configuration data should also fail the device restore to prevent invalid PAV assignment. The failed device may get restored after additional paths get available later on. If the restore fails after the device was added to the lcu alias handling it needs to be removed from the alias handling before exiting the restore function.

2015-11-03mac80211: fixup AIFSN instead of disabling WMMEmmanuel Grumbach
Disabling WMM has a huge impact these days. It implies that HT and VHT will be disabled which means that the throughput will be drammatically reduced. Since the AIFSN is a transmission parameter, we can play a bit and fix it up to make it compliant with the 802.11 specification which requires it to be at least 2. Increasing it from 1 to 2 will slightly reduce the likelyhood to get a transmission opportunity compared to other clients that would accept to set AIFSN=1, but at least it will allow HT and VHT which is a huge gain.

2015-11-03mac80211: use freezable workqueue for restart workEliad Peller
Requesting hw restart during suspend might result in the restart work being executed after mac80211 and the hw are suspended. Solve the race by simply scheduling the restart work on a freezable workqueue. Note that there can be some cases of reconfiguration on resume (besides the hardware restart): * wowlan is not configured - All the interfaces removed were removed on suspend, and drv_stop() was called. At this point the driver shouldn't expect for hw_restart anyway, so we can simply cancel it (on resume). * wowlan is configured, drv_resume() == 1 There is no definitive expected behavior in this case, as each driver might have different expectations (e.g. setting some flags on suspend/restart vs. not handling spurious recovery). For now, simply let the hw_restart work run again after resume, and hope the driver will handle it well (or at least initiate another hw restart).

2015-11-03leds: bcm6328: add missing of_node_putJulia Lawall
for_each_available_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_available_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | + of_node_put(child); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
