commit f5d636d2 upstream. Testing the update pending bit directly after issuing an update is nonsense cause depending on the pixel clock the CRTC needs a bit of time to execute the flip even when we are in the VBLANK period. This is just a non invasive patch to solve the problem at hand, a more complete and cleaner solution should follow in the next merge window.

commit 7f1950fb upstream. Depending on the SDVO output_flags SDVO may have multiple connectors linking to the same encoder (in intel_connector->encoder->base). Only one of those connectors should be active (ie link to the encoder thru drm_connector->encoder). If intel_connector_break_all_links() is called from intel_sanitize_crtc() we may break the crtc connection of an encoder thru an inactive connector in which case intel_connector_break_all_links() will not be called again for the active connector if this happens to come later in the list due to: if (connector->encoder->base.crtc != &crtc->base) continue; in intel_sanitize_crtc(). This will however leave the drm_connector->encoder linkage for this active connector in place. Subsequently this will cause multiple warnings in intel_connector_check_state() to trigger and the driver will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL). To avoid this remove intel_connector_break_all_links() and move its code to its two calling functions: intel_sanitize_crtc() and intel_sanitize_encoder(). This allows to implement the link breaking more flexibly matching the surrounding code: ie. in intel_sanitize_crtc() we can break the crtc link separatly after the links to the encoders have been broken which avoids above problem. This regression has been introduced in: commit 24929352 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jul 2 20:28:59 2012 +0200 drm/i915: read out the modeset hw state at load and resume time so goes back to the very beginning of the modeset rework. v2: This patch takes care of the concernes voiced by Chris Wilson and Daniel Vetter that only breaking links if the drm_connector is linked to an encoder may miss some links. v3: move all encoder handling to encoder loop as suggested by Daniel Vetter.

commit 3ff04a16 upstream. The status bits are unconditionally set, the control bits only enable the actual interrupt generation. Which means if we get some random other interrupts we'll bogusly complain about them. So restrict the WARN to platforms with a sane hotplug interrupt handling scheme.

commit 9953599b upstream. ... our current modeset code isn't good enough yet to handle this. The scenario is: 1. BIOS sets up a cloned config with lvds+external screen on the same pipe, e.g. pipe B. 2. We read out that state for pipe B and assign the gmch_pfit state to it. 3. The initial modeset switches the lvds to pipe A but due to lack of atomic modeset we don't recompute the config of pipe B. -> both pipes now claim (in the sw pipe config structure) to use the gmch_pfit, which just won't work.

commit 40478455 upstream. In commit commit 6375b768 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

commit 830cbe4b upstream. Until now, we were leaving the ->check_device() msi_chip operation empty, which leads the PCI core to believe that we support both MSI and MSI-X.

commit da343fc7 upstream. The armada_370_xp_alloc_msi() function returns a signed int, which is negative on error. However, we store the return value into an irq_hw_number_t, which is unsigned. Therefore, we actually never test if armada_370_xp_alloc_msi() returns an error or not, which may lead us to use hwirq numbers of as 0xffffffe4 (when armada_370_xp_alloc_msi() returns -ENOSPC). This commit fixes that by storing the return value of armada_370_xp_alloc_msi() in a signed variable. Fixes: 31f614ed ('irqchip: armada-370-xp: implement MSI support') Signed-off-by:

commit 3eba563e upstream. Address a regression caused by commit ad332c8a: (ACPI / EC: Clear stale EC events on Samsung systems) After the earlier patch, there was found to be a race condition on some earlier Samsung systems (N150/N210/N220). The function acpi_ec_clear was sometimes discarding a new EC event before its GPE was triggered by the system. In the case of these systems, this meant that the "lid open" event was not registered on resume if that was the cause of the wake, leading to problems when attempting to close the lid to suspend again. After testing on a number of Samsung systems, both those affected by the previous EC bug and those affected by the race condition, it seemed that the best course of action was to process rather than discard the events. On Samsung systems which accumulate stale EC events, there does not seem to be any adverse side-effects of running the associated _Q methods. This patch adds an argument to the static function acpi_ec_sync_query so that it may be used within the acpi_ec_clear loop in place of acpi_ec_query_unlocked which was used previously. With thanks to Stefan Biereigel for reporting the issue, and for all the people who helped test the new patch on affected systems.

commit a8d22396 upstream. The ACPI PNP subsystem returns errors from pnpacpi_set_resources() and pnpacpi_disable_resources() if the _SRS or _DIS methods are not present, respectively, but it should not do that, because those methods are optional. For this reason, modify pnpacpi_set_resources() and pnpacpi_disable_resources(), respectively, to ignore missing _SRS or _DIS. This problem has been uncovered by commit 202317a5 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace) and manifested itself by causing serial port suspend to fail on some systems.

commit 0f62fb22 upstream. If an md array with externally managed metadata (e.g. DDF or IMSM) is in use, then we should not set safemode==2 at shutdown because: 1/ this is ineffective: user-space need to be involved in any 'safemode' handling, 2/ The safemode management code doesn't cope with safemode==2 on external metadata and md_check_recover enters an infinite loop. Even at shutdown, an infinite-looping process can be problematic, so this could cause shutdown to hang. Signed-off-by:

commit 84ea7fe3 upstream. switch_hrtimer_base() calls hrtimer_check_target() which ensures that we do not migrate a timer to a remote cpu if the timer expires before the current programmed expiry time on that remote cpu. But __hrtimer_start_range_ns() calls switch_hrtimer_base() before the new expiry time is set. So the sanity check in hrtimer_check_target() is operating on stale or even uninitialized data. Update expiry time before calling switch_hrtimer_base(). [ tglx: Rewrote changelog once again ] Signed-off-by:

commit 012a45e3 upstream. If a cpu is idle and starts an hrtimer which is not pinned on that same cpu, the nohz code might target the timer to a different cpu. In the case that we switch the cpu base of the timer we already have a sanity check in place, which determines whether the timer is earlier than the current leftmost timer on the target cpu. In that case we enqueue the timer on the current cpu because we cannot reprogram the clock event device on the target. If the timers base is already the target CPU we do not have this sanity check in place so we enqueue the timer as the leftmost timer in the target cpus rb tree, but we cannot reprogram the clock event device on the target cpu. So the timer expires late and subsequently prevents the reprogramming of the target cpu clock event device until the previously programmed event fires or a timer with an earlier expiry time gets enqueued on the target cpu itself. Add the same target check as we have for the switch base case and start the timer on the current cpu if it would become the leftmost timer on the target.

commit 6c6c0d5a upstream. If the last hrtimer interrupt detected a hang it sets hang_detected=1 and programs the clock event device with a delay to let the system make progress. If hang_detected == 1, we prevent reprogramming of the clock event device in hrtimer_reprogram() but not in hrtimer_force_reprogram(). This can lead to the following situation: hrtimer_interrupt() hang_detected = 1; program ce device to Xms from now (hang delay) We have two timers pending: T1 expires 50ms from now T2 expires 5s from now Now T1 gets canceled, which causes hrtimer_force_reprogram() to be invoked, which in turn programs the clock event device to T2 (5 seconds from now). Any hrtimer_start after that will not reprogram the hardware due to hang_detected still being set. So we effectivly block all timers until the T2 event fires and cleans up the hang situation. Add a check for hang_detected to hrtimer_force_reprogram() which prevents the reprogramming of the hang delay in the hardware timer. The subsequent hrtimer_interrupt will resolve all outstanding issues. [ tglx: Rewrote subject and changelog and fixed up the comment in hrtimer_force_reprogram() ] Signed-off-by:

commit 58b116bc upstream. When the kernel is built with CONFIG_PREEMPT it is possible to reach a state when all modules loaded but some driver still stuck in the deferred list and there is a need for external event to kick the deferred queue to probe these drivers. The issue has been observed on embedded systems with CONFIG_PREEMPT enabled, audio support built as modules and using nfsroot for root filesystem. The following log fragment shows such sequence when all audio modules were loaded but the sound card is not present since the machine driver has failed to probe due to missing dependency during it's probe. The board is am335x-evmsk (McASP<->tlv320aic3106 codec) with davinci-evm machine driver: ...

McASP driver already executing it's probing (since 12.615118). The machine driver tries to construct the sound card (12.950839) but did not found one of the components so it fails. After this McASP driver registers all the ASoC components (the machine driver still in it's probe function after it failed to construct the card) and the deferred work is prepared at 13.099026 (note that this time the machine driver is not in the lists so it is not going to be handled when the work is executing). Lastly the machine driver exit from it's probe and the core places it to the deferred list but there will be no other driver going to load and the deferred queue is not going to be kicked again - till we have external event like connecting USB stick, etc. The proposed solution is to try the deferred queue once more when the last driver is asking for deferring and we had drivers loaded while this last driver was probing. This way we can avoid drivers stuck in the deferred queue. Signed-off-by:

commit c0940e95 upstream. This reverts commit 9fb6c9c7. Tjmax on some Intel CPUs is below 85 degrees C. One known example is L5630 with Tjmax of 71 degrees C. There are other Xeon processors with Tjmax of 70 or 80 degrees C. Also, the Intel IA32 System Programming document states that the temperature target is in bits 23:16 of MSR 0x1a2 (MSR_TEMPERATURE_TARGET), which is 8 bits, not 7. So even if turbostat uses similar checks to validate Tjmax, there is no evidence that the checks are actually required. On the contrary, the checks are known to cause problems and therefore need to be removed. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=75071.

commit 79465d2f upstream. We remove the waiting module removal in commit 3f2b9c9c (September 2013), but it turns out that modprobe in kmod (< version 16) was asking for waiting module removal. No one noticed since modprobe would check for 0 usage immediately before trying to remove the module, and the race is unlikely. However, it means that anyone running old (but not ancient) kmod versions is hitting the printk designed to see if anyone was running "rmmod -w".
