Specifics: - I2C and SPI devices are expected to be enumerated by the I2C and SPI subsystems, respectively, but due to a change made during the 4.11 cycle, in some cases the ACPI core marks them as already enumerated which causes the I2C and SPI subsystems to overlook them, so fix that (Jarkko Nikula)" * tag 'acpi-4.12-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: Fix enumeration for special SPI and I2C devices

2017-06-21ACPI / scan: Fix enumeration for special SPI and I2C devicesJarkko Nikula1-30/+37
Commit f406270bf73d ("ACPI / scan: Set the visited flag for all enumerated devices") caused that two group of special SPI or I2C devices do not enumerate. SPI and I2C devices are expected to be enumerated by the SPI and I2C subsystems but change caused that acpi_bus_attach() marks those devices with acpi_device_set_enumerated(). First group of devices are matched using Device Tree compatible property with special _HID "PRP0001". Those devices have matched scan handler, acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them with acpi_device_set_enumerated(). Second group of devices without valid _HID such as "LNXVIDEO" have device->pnp.type.platform_id set to zero and change again marks them with acpi_device_set_enumerated(). Fix this by flagging the SPI and I2C devices during struct acpi_device object initialization time and let the code in acpi_bus_attach() to go through the device_attach() and acpi_default_enumeration() path for all SPI and I2C devices.

2017-06-21dm io: fix duplicate bio completion due to missing ref countMike Snitzer1-2/+2
If only a subset of the devices associated with multiple regions support a given special operation (eg. DISCARD) then the dec_count() that is used to set error for the region must increment the io->count. Otherwise, when the dec_count() is called it can cause the dm-io caller's bio to be completed multiple times. As was reported against the dm-mirror target that had mirror legs with a mix of discard capabilities.

As it turns out more than just Armada 370 and XP support using GPIO lines as PWM lines. For example the Armada 38x family has the same hardware support. As such "marvell,armada-370-xp-gpio" for the compatible string is a misnomer. Change the compatible string to "marvell,armada-370-gpio" before the driver makes it out of the -rc stage. This also follows the practice of using only the first device family supported as part of the name. Also update the documentation and comments in the code accordingly.

2017-06-19random: silence compiler warnings and fix raceJason A. Donenfeld1-6/+6
Odd versions of gcc for the sh4 architecture will actually warn about flags being used while uninitialized, so we set them to zero. Non crazy gccs will optimize that out again, so it doesn't make a difference. Next, over aggressive gccs could inline the expression that defines use_lock, which could then introduce a race resulting in a lock imbalance. By using READ_ONCE, we prevent that fate. Finally, we make that assignment const, so that gcc can still optimize a nice amount. Finally, we fix a potential deadlock between primary_crng.lock and batched_entropy_reset_lock, where they could be called in opposite order. Moving the call to invalidate_batched_entropy to outside the lock rectifies this issue. Fixes: b169c13de473a85b3c859bb36216a4cb5f00a54a Signed-off-by: Jason A.

Maarten and Ville noticed that we are enabling backlight via DP aux very early in the modeset_init path via the intel_dp_aux_setup_backlight() function, since commit e7156c833903 ("drm/i915: Add Backlight Control using DPCD for eDP connectors (v9)"). Looks like all we need to do during _setup_backlight() is read the current brightness state instead of modifying it. v2: Rewrote commit message.

2017-06-19ntb_transport: fix bug calculating num_qps_mwLogan Gunthorpe1-2/+2
A divide by zero error occurs if qp_count is less than mw_count because num_qps_mw is calculated to be zero. The calculation appears to be incorrect. The requirement is for num_qps_mw to be set to qp_count / mw_count with any remainder divided among the earlier mws. For example, if mw_count is 5 and qp_count is 12 then mws 0 and 1 will have 3 qps per window and mws 2 through 4 will have 2 qps per window. Thus, when mw_num < qp_count % mw_count, num_qps_mw is 1 higher than when mw_num >= qp_count.

2017-06-19ntb_transport: fix qp count bugLogan Gunthorpe1-2/+2
In cases where there are more mw's than spads/2-2, the mw count gets reduced to match the limitation. ntb_transport also tries to ensure that there are fewer qps than mws but uses the full mw count instead of the reduced one. When this happens, the math in 'ntb_transport_setup_qp_mw' will get confused and result in a kernel paging request bug. This patch fixes the bug by reducing qp_count to the reduced mw count instead of the full mw count.

2017-06-19cxgb4: notify uP to route ctrlq compl to rdma rspqRaju Rangoju1-4/+6
During the module initialisation there is a possible race (basically race between uld and lld) where neither the uld nor lld notifies the uP about where to route the ctrl queue completions. LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

2017-06-19drm/i915: Remove __GFP_NORETRY from our buffer allocatorChris Wilson1-1/+14
I tried __GFP_NORETRY in the belief that __GFP_RECLAIM was effective. It struggles with handling reclaim of our dirty buffers and relies on reclaim via kswapd. As a result, a single pass of direct reclaim is unreliable when i915 occupies the majority of available memory, and the only means of effectively waiting on kswapd to amke progress is by not setting the __GFP_NORETRY flag and lopping. That leaves us with the dilemma of invoking the oomkiller instead of propagating the allocation failure back to userspace where it can be handled more gracefully (one hopes). In the future we may have __GFP_MAYFAIL to allow repeats up until we genuinely run out of memory and the oomkiller would have been invoked. Until then, let the oomkiller wreck havoc. v2: Stop playing with side-effects of gfp flags and await __GFP_MAYFAIL v3: Update comments that direct reclaim only appears to be ignoring our dirty buffers!

2017-06-19drm/i915: Encourage our shrinker more when our shmemfs allocations failsChris Wilson1-21/+29
Commit 24f8e00a8a2e ("drm/i915: Prefer to report ENOMEM rather than incur the oom for gfx allocations") made the bold decision to try and avoid the oomkiller by reporting -ENOMEM to userspace if our allocation failed after attempting to free enough buffer objects. In short, it appears we were giving up too easily (even before we start wondering if one pass of reclaim is as strong as we would like). Part of the problem is that if we only shrink just enough pages for our expected allocation, the likelihood of those pages becoming available to us is less than 100% To counter-act that we ask for twice the number of pages to be made available. Furthermore, we allow the shrinker to pull pages from the active list in later passes. v2: Be a little more cautious in paging out gfx buffers, and leave that to a more balanced approach from shrink_slab(). Important when combined with "drm/i915: Start writeback from the shrinker" as anything shrunk is immediately swapped out and so should be more conservative.
