2015-03-09vt6655: Fix late setting of byRFType.Malcolm Priestley
byRFType is not set prior to registration of mac80211 causing unpredictable operation after channel scans. With byRFType unset all channels are enabled this causes tx power to be set to values not present its eeprom. Move setting of this variable to vt6655_probe. byRFType must have a mask set. byRevId not used by driver and is removed.

2015-03-01staging: comedi: adv_pci1710: fix AI INSN_READ for non-zero channelIan Abbott
Reading of analog input channels by the `INSN_READ` comedi instruction is broken for all except channel 0. `pci171x_ai_insn_read()` calls `pci171x_ai_read_sample()` with the wrong value for the third parameter. It is supposed to be the current index in a channel list (which is always of length 1 in this case, so the index should be 0), but instead it is passing the actual channel number. `pci171x_ai_read_sample()` checks the channel number encoded in the raw sample value read from the hardware matches the channel number stored in the specified index of the previously set up channel list and returns `-ENODATA` if it doesn't match. Since the index should always be 0 in this case, the match will fail unless the channel number is also 0. Fix it by passing 0 as the channel index. Note that when the bug first appeared, it was `pci171x_ai_dropout()` that was called with the wrong parameter value. `pci171x_ai_dropout()` got replaced with `pci171x_ai_read_sample()` in commit 7fd2dae2500d ("staging: comedi: adv_pci1710: introduce pci171x_ai_read_sample()").

2015-02-28staging: comedi: vmk80xx: remove "firmware version" kernel messagesH Hartley Sweeten
During the attach of this driver a couple commands are sent to the hardware with usb_bulk_msg() to read the firmware version information. This information is then dumped as dev_info() kernel messages. Thee messages are just added noise and don't effect the operation of the driver. For simplicity, remove the messages as well as the then unused functions vmk80xx_read_eeprom() and vmk80xx_check_data_link(). This also fixes an issue reported by coverity about an out-of-bounds write in vmk80xx_read_eeprom().

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of fixes for IIO in the 4.0 cycle. Note a followup set dependent on patches in the recent merge windows will follow shortly. * dht11 - fix a read off the end of an array, add some locking to prevent the read function being interrupted and make sure gpio/irq lines are not enabled for irqs during output. * iadc - timeout should be in jiffies not msecs * mpu6050 - avoid a null id from ACPI emumeration being dereferenced. * mxs-lradc - fix up some interaction issues between the touchscreen driver and iio driver. Mostly about making sure that the adc driver only affects channels that are not being used for the touchscreen. * ad2s1200 - sign extension fix for a result of c type promotion. * adis16400 - sign extension fix for a result of c type promotion. * mcp3422 - scale table was transposed. * ad5686 - use _optional regulator get to avoid a dummy reg being allocate which would cause the driver to fail to initialize. * gp2ap020a00f - select REGMAP_I2C * si7020 - revert an incorrect cleanup up and then fix the issue that made that cleanup seem like a good idea.

2015-02-11oom: add helpers for setting and clearing TIF_MEMDIEMichal Hocko
This patchset addresses a race which was described in the changelog for 5695be142e20 ("OOM, PM: OOM killed task shouldn't escape PM suspend"): : PM freezer relies on having all tasks frozen by the time devices are : getting frozen so that no task will touch them while they are getting : frozen. But OOM killer is allowed to kill an already frozen task in order : to handle OOM situtation. In order to protect from late wake ups OOM : killer is disabled after all tasks are frozen. This, however, still keeps : a window open when a killed task didn't manage to die by the time : freeze_processes finishes. The original patch hasn't closed the race window completely because that would require a more complex solution as it can be seen by this patchset. The primary motivation was to close the race condition between OOM killer and PM freezer _completely_. As Tejun pointed out, even though the race condition is unlikely the harder it would be to debug weird bugs deep in the PM freezer when the debugging options are reduced considerably. I can only speculate what might happen when a task is still runnable unexpectedly. On a plus side and as a side effect the oom enable/disable has a better (full barrier) semantic without polluting hot paths. I have tested the series in KVM with 100M RAM: - many small tasks (20M anon mmap) which are triggering OOM continually - s2ram which resumes automatically is triggered in a loop echo processors > /sys/power/pm_test while true do echo mem > /sys/power/state sleep 1s done - simple module which allocates and frees 20M in 8K chunks. If it sees freezing(current) then it tries another round of allocation before calling try_to_freeze - debugging messages of PM stages and OOM killer enable/disable/fail added and unmark_oom_victim is delayed by 1s after it clears TIF_MEMDIE and before it wakes up waiters. - rebased on top of the current mmotm which means some necessary updates in mm/oom_kill.c. mark_tsk_oom_victim is now called under task_lock but I think this should be OK because __thaw_task shouldn't interfere with any locking down wake_up_process. Oleg? As expected there are no OOM killed tasks after oom is disabled and allocations requested by the kernel thread are failing after all the tasks are frozen and OOM disabled. I wasn't able to catch a race where oom_killer_disable would really have to wait but I kinda expected the race is really unlikely.

The first 2 patches are simple cleanups for OOM. They should go in regardless the rest IMO. Patches 3 and 4 are trivial printk -> pr_info conversion and they should go in ditto. The main patch is the last one and I would appreciate acks from Tejun and Rafael. I think the OOM part should be OK (except for __thaw_task vs. task_lock where a look from Oleg would appreciated) but I am not so sure I haven't screwed anything in the freezer code. I have found several surprises there. This patch (of 5): This patch is just a preparatory and it doesn't introduce any functional change. Note: I am utterly unhappy about lowmemory killer abusing TIF_MEMDIE just to wait for the oom victim and to prevent from new killing. This is just a side effect of the flag. The primary meaning is to give the oom victim access to the memory reserves and that shouldn't be necessary here.

A few redundant switch cases as well as a redundant if/else within one of the cases was consolidated to a single call. The cases are intentionally retained for documentation purposes. case WIFI_REASSOCREQ,WIFI_PROBEREQ,WIFI_BEACON,WIFI_ACTION all have the same effect - notably the also for WIFI_PROBEREQ where the if/else is executing the same function. These redundant cases could all be dropped and consolidated into the default but probably it is better for documentation/readability to leave them in the switch/case explicitly.

It is possible that when fld client is trying to lookup seq on one of MDT, but the connection between the client and the MDT is not being initialized yet, especially during striped dir creation, because client will only send create req to the master MDT, then master MDT will distribute the operation to all of other MDT, instead of client distributing these requests, which will usually trigger the connection. In this case, we will send the fld request to MDT0, since it has all of location information.
