2015-02-09drm/i915: Insert a command barrier on BLT/BSD cache flushesChris Wilson
This looked like an odd regression from commit ec5cc0f9b019af95e4571a9fa162d94294c8d90b Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jun 12 10:28:55 2014 +0100 drm/i915: Restrict GPU boost to the RCS engine but in reality it undercovered a much older coherency bug. The issue that boosting the GPU frequency on the BCS ring was masking was that we could wake the CPU up after completion of a BCS batch and inspect memory prior to the write cache being fully evicted. In order to serialise the breadcrumb interrupt (and so ensure that the CPU's view of memory is coherent) we need to perform a post-sync operation in the MI_FLUSH_DW. v2: Fix all the MI_FLUSH_DW (bsd plus the duplication in execlists). Also fix the invalidate_domains mask in gen8_emit_flush() for ring != VCS.

2015-02-09genirq: Fix null pointer reference in irq_set_affinity_hint()Jesse Brandeburg
The recent set_affinity commit by me introduced some null pointer dereferences on driver unload, because some drivers call this function with a NULL argument.

2015-02-09cfq-iosched: handle failure of cfq group allocationKonstantin Khlebnikov
Cfq_lookup_create_cfqg() allocates struct blkcg_gq using GFP_ATOMIC. In cfq_find_alloc_queue() possible allocation failure is not handled. As a result kernel oopses on NULL pointer dereference when cfq_link_cfqq_cfqg() calls cfqg_get() for NULL pointer. Bug was introduced in v3.5 in commit cd1604fab4f9 ("blkcg: factor out blkio_group creation"). Prior to that commit cfq group lookup had returned pointer to root group as fallback. This patch handles this error using existing fallback oom_cfqq.

2015-02-09drm/i915: Drop vblank wait from intel_dp_link_downDaniel Vetter
Nothing in Bspec seems to indicate that we actually needs this, and it looks like can't work since by this point the pipe is off and so vblanks won't really happen any more. Note that Bspec mentions that it takes a vblank for this bit to change, but _only_ when enabling. Dropping this code quenches an annoying backtrace introduced by the more anal checking since commit 51e31d49c89055299e34b8f44d13f70e19aaaad1 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 15 12:36:02 2014 +0200 drm/i915: Use generic vblank wait Note: This fixes the fallout from the above commit, but does not address the shortcomings of the IBX transcoder select workaround implementation discussed during review [1].

2015-02-09ALSA: usb: update trigger timestamp on first non-zero URB submittedPierre-Louis Bossart
The first URBs are submitted during the prepare stage. When .trigger is called, the ALSA core saves a trigger tstamp that doesn't correspond to the actual time when the samples are submitted. The trigger_tstamp is now updated when the first data are submitted to avoid any time offsets. A usb-specific trigger_tstamp_pending_update flag is used for now, at some point the flag would need to move to the ALSA core, USB is not the only interface where silent block transfers are programmed as part of the prepare stage, with actual data enabled when .trigger is called.

2015-02-09drm/i915: Correct the IOSF Dev_FN field for IOSF transfersShobhit Kumar
As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target device and not the source. So PCI_DEVFN(2,0) is not correct. Further the port ID should be enough to identify devices unless they are MFD. The SB_DevFn was intended to remove ambiguity in case of these MFD devices. For non MFD devices the recommendation for the target device IP was to ignore these fields, but not all of them followed the recommendation. Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0). It turned out that this did not follow the recommendation and expected 0 in this field. In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for all devices except target PCI devices.

2015-02-09KVM: s390: add cpu model supportMichael Mueller
This patch enables cpu model support in kvm/s390 via the vm attribute interface. During KVM initialization, the host properties cpuid, IBC value and the facility list are stored in the architecture specific cpu model structure. During vcpu setup, these properties are taken to initialize the related SIE state. This mechanism allows to adjust the properties from user space and thus to implement different selectable cpu models. This patch uses the IBC functionality to block instructions that have not been implemented at the requested CPU type and GA level compared to the full host capability. Userspace has to initialize the cpu model before vcpu creation. A cpu model change of running vcpus is not possible.
