2017-03-23drm/i915/execlists: Relax the locked clear_bit(IRQ_EXECLIST)Chris Wilson1-1/+11
We only need to care about the ordering of the clearing of the bit with the uncached CSB read in order to correctly detect a new interrupt before the read completes. The uncached read itself acts as a full memory barrier, so we do not need to enforce another in the form of a locked clear_bit. v2: Clarify why the split and unlocked test/clear is harmless.

This has been around for a long time but it's finally fixed. f_hid learned that it should never access hidg->req without first grabbing the spinlock. Roger Quadros fixed two bugs in the f_uvc function driver. Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather difficult to trigger. When we're dealing with bounced EP0 requests, we should delay unmap until after ->complete() is called. UDC class got a use-after-free fix.

2017-03-23xen/acpi: upload PM state from init-domain to XenAnkur Arora1-8/+26
This was broken in commit cd979883b9ed ("xen/acpi-processor: fix enabling interrupts on syscore_resume"). do_suspend (from xen/manage.c) and thus xen_resume_notifier never get called on the initial-domain at resume (it is if running as guest.) The rationale for the breaking change was that upload_pm_data() potentially does blocking work in syscore_resume(). This patch addresses the original issue by scheduling upload_pm_data() to execute in workqueue context.

2017-03-23drm/i915/guc: A little bit more of doorbell sanitizationOscar Mateo2-114/+138
Some recent refactoring patches have left the doorbell creation outside the GuC client allocation, which does not make a lot of sense (a client without a doorbell is something useless). Move it back there, and refactor the init_doorbell_hw consequently. Thanks to this, we can do some other improvements, like hoisting the check for GuC submission enabled out of the enable function. v2: Rebased.

2017-03-23drm/i915: Restore marking context objects as dirty on pinningChris Wilson1-0/+2
Commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") converted the legacy intel_ringbuffer submission to the same context pinning mechanism as execlists - that is to pin the context until the subsequent request is retired. Previously it used the vma retirement of the context object to keep itself pinned until the next request (after i915_vma_move_to_active()). In the conversion, I missed that the vma retirement was also responsible for marking the object as dirty. Mark the context object as dirty when pinning (equivalent to execlists) which ensures that if the context is swapped out due to mempressure or suspend/hibernation, when it is loaded back in it does so with the previous state (and not all zero).

2017-03-23mmc: sdhci-pci: Do not disable interrupts in sdhci_intel_set_powerAdrian Hunter1-0/+4
Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting.
