2016-11-15IB/hfi1: Fix a potential memory leak in hfi1_create_ctxts()Jianxin Xiong
In the function hfi1_create_ctxts the array "dd->rcd" is allocated and then populated with allocated resources in a loop. Previously, if error happened during the loop, only resource allocated in the current iteration would be freed. The array itself would then be freed, leaving the resources that were allocated in previous iterations and referenced by the array elements in limbo. This patch makes sure all allocated resources are freed before freeing the array "dd->rcd". Also the resource allocation now takes account of the numa node the device is attached to.

2016-11-15IB/rdmavt: rdmavt can handle non aligned page mapsDennis Dalessandro
The initial code for rdmavt carried with it a restriction that was a vestige from the qib driver, that to dma map a page it had to be less than a page size. This is not the case on modern hardware, both qib and hfi1 will be just fine with unaligned map requests. This fixes a 4.8 regression where by an IPoIB transfer of > PAGE_SIZE will hang because the dma map page call always fails. This was introduced after commit 5faba5469522 ("IB/ipoib: Report SG feature regardless of HW UD CSUM capability") added the capability to use SG by default. Rather than override this, the HW supports it, so allow SG.

2016-11-15ath9k: Switch to using mac80211 intermediate software queues.Toke Høiland-Jørgensen
This switches ath9k over to using the mac80211 intermediate software queueing mechanism for data packets. It removes the queueing inside the driver, except for the retry queue, and instead pulls from mac80211 when a packet is needed. The retry queue is used to store a packet that was pulled but can't be sent immediately. The old code path in ath_tx_start that would queue packets has been removed completely, as has the qlen limit tunables (since there's no longer a queue in the driver to limit). The mac80211 intermediate software queues offer significant latency reductions, and this patch allows ath9k to realise them. The exact gains from this varies with the test scenario, but in an access point scenario we have seen latency reductions ranging from 1/3 to as much as an order of magnitude. We also achieve slightly better aggregation. Median latency (ping) figures with this patch applied at the access point, with two high-rate stations and one low-rate station (HT20 5Ghz), running a Flent rtt_fair_var_up test with one TCP flow and one ping flow going to each station: Fast station Slow station Default pfifo_fast qdisc: 430.4 ms 638.7 ms fq_codel qdisc on iface: 35.5 ms 211.8 ms This patch set: 22.4 ms 38.2 ms Median aggregation sizes over the same test: Default pfifo_fast qdisc: 9.5 pkts 1.9 pkts fq_codel qdisc on iface: 11.2 pkts 1.9 pkts This patch set: 13.9 pkts 1.9 pkts This patch is based on Tim's original patch set, but reworked quite thoroughly.

2016-11-15ath9k: Really fix LED polarity for some Mini PCI AR9220 MB92 cards.Vittorio Gambaletta (VittGam)
The active_high LED of my Wistron DNMA-92 is still being recognized as active_low on 4.7.6 mainline. When I was preparing my former commit 0f9edcdd88a9 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards.") to fix that I must have somehow messed up with testing, because I tested the final version of that patch before sending it, and it was apparently working; but now it is not working on 4.7.6 mainline. I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the PCI_VDEVICE section for 0x0029; but then I moved the former below the latter after seeing how 0x002A sections were sorted in the file. This turned out to be wrong: if a generic PCI_VDEVICE entry (that has both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will match first and will be used. With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6. While I'm at it, let's fix 0x002A too by also moving its generic definition below its specific ones.

2016-11-15mac80211_hwsim: fix beacon delta calculationBenjamin Beichler
Due to the cast from uint32_t to int64_t, a wrong next beacon timing is calculated and effectively the beacon timer stops working. This is especially bad for 802.11s mesh networks, because discovery breaks without beacons.

2016-11-15locking/mutex, drm: Introduce mutex_trylock_recursive()Peter Zijlstra
By popular DRM demand, introduce mutex_trylock_recursive() to fix up the two GEM users. Without this it is very easy for these drivers to get stuck in low-memory situations and trigger OOM. Work is in progress to remove the need for this in at least i915.

2016-11-15Fix USB CB/CBI storage devices with CONFIG_VMAP_STACK=yPetr Vandrovec
Some code (all error handling) submits CDBs that are allocated on the stack. This breaks with CB/CBI code that tries to create URB directly from SCSI command buffer - which happens to be in vmalloced memory with vmalloced kernel stacks. Let's make copy of the command in usb_stor_CB_transport.

2016-11-15gpio: do not double-check direction on sleeping chipsLinus Walleij
When locking a GPIO line as IRQ, we go to lengths to double-check that the line is really set as input before marking it as used for IRQ. This is not good on GPIO chips that can sleep, because this function is called in IRQ-safe context. Just skip this if it can't be checked quickly. Currently this happens on sleeping expanders such as STMPE or TC3589x: BUG: scheduling while atomic: swapper/1/0x00000002 Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 4.9.0-rc1+ #38 Hardware name: Nomadik STn8815 [<c000f2e0>] (unwind_backtrace) from [<c000d244>] (show_stack+0x10/0x14) [<c000d244>] (show_stack) from [<c0037b78>] (__schedule_bug+0x54/0x80) [<c0037b78>] (__schedule_bug) from [<c042df14>] (__schedule+0x3a0/0x460) [<c042df14>] (__schedule) from [<c042e028>] (schedule+0x54/0xb8) (...)

2016-11-14scsi: qla2xxx: do not abort all commands in the adapter during EEH recoveryMauricio Faria de Oliveira
The previous commit 1535aa75a3d8 ("qla2xxx: fix invalid DMA access after command aborts in PCI device remove") introduced a regression during an EEH recovery, since the change to the qla2x00_abort_all_cmds() function calls qla2xxx_eh_abort(), which verifies the EEH recovery condition but handles it heavy-handed. (commit a465537ad1a4 "qla2xxx: Disable the adapter and skip error recovery in case of register disconnect.") This problem warrants a more general/optimistic solution right into qla2xxx_eh_abort() (eg in case a real command abort arrives during EEH recovery, or if it takes long enough to trigger command aborts); but it's still worth to add a check to ensure the code added by the previous commit is correct and contained within its owner function. This commit just adds a 'if (!ha->flags.eeh_busy)' check around it. (ahem; a trivial fix for this -rc series; sorry for this oversight.) With it applied, both PCI device remove and EEH recovery works fine.
