2015-05-19drm/exynos: mixer: cleanup pixelformat handlingTobias Jakobi
Move the defines for the pixelformats that the mixer supports out of mixer_graph_buffer() to the top of the source. Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on the plane's pf (and not bpp). Also add handling of RGB565 and XRGB1555 to the switch statement and exit early if the plane has an unsupported pf. Partially based on 'drm/exynos: enable/disable blend based on pixel format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>. v2: Use the shorter MXR_FORMAT as prefix. v3: Re-add ARGB8888 because of compatibility reasons (suggested by Joonyoung Shim).

2015-05-19drm/exynos: mixer: remove buffer count handling in vp_video_buffer()Tobias Jakobi
The video processor (VP) supports four formats: NV12, NV21 and its tiled variants. All these formats are bi-planar, so the buffer count in vp_video_buffer() is always 2. Also properly exit if we're called with an invalid (non-VP) pixelformat.

2015-05-19drm/exynos: plane: honor buffer offset for dma_addrTobias Jakobi
Previously we were ignoring the buffer offsets that are passed through the addfb2 ioctl. This didn't cause any major issues, since for uni-planar formats (like XRGB8888) userspace would most of the time just use offsets[0]=0. However with NV12 offsets[1] is very likely non-zero. So properly apply the offsets to our dma addresses.

2015-05-19drm/exynos: fb: use drm_format_num_planes to get buffer countTobias Jakobi
The previous code had some special case handling for the buffer count in exynos_drm_format_num_buffers(). This code was incorrect though, since this special case doesn't exist for DRM. It stemmed from the existence of the special NV12M V4L2 format. NV12 is a bi-planar format (separate planes for luma and chroma) and V4L2 differentiates between a NV12 buffer where luma and chroma is contiguous in memory (so no data between luma/chroma), and a NV12 buffer where luma and chroma have two explicit memory locations (which is then called NV12M). This distinction doesn't exist for DRM. A bi-planar format always explicitly comes with the information about its two planes (even if these planes should be contiguous).

2015-05-19genirq: Introduce irq_set_vcpu_affinity() to target an interrupt to a VCPUJiang Liu
With Posted-Interrupts support in Intel CPU and IOMMU, an external interrupt from assigned-devices could be directly delivered to a virtual CPU in a virtual machine. Instead of hacking KVM and Intel IOMMU drivers, we propose a platform independent interface to target an interrupt to a specific virtual CPU in a virtual machine, or set virtual CPU affinity for an interrupt. By adopting this new interface and the hierarchy irqdomain, we could easily support posted-interrupts on Intel platforms, and also provide flexible enough interfaces for other platforms to support similar features. Here is the usage scenario for this interface: Guest update MSI/MSI-X interrupt configuration -->QEMU and KVM handle this -->KVM call this interface (passing posted interrupts descriptor and guest vector) -->irq core will transfer the control to IOMMU -->IOMMU will do the real work of updating IRTE (IRTE has new format for VT-d Posted-Interrupts) Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Signed-off-by: Feng Wu <feng.wu@intel.com> Link: http://lkml.kernel.org/r/1432026437-16560-2-git-send-email-feng.wu@intel.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2015-05-19ALSA: pcm: Modify double acknowledged interrupts check conditionKoro Chen
Currently in snd_pcm_update_hw_ptr0 during interrupt, we consider there were double acknowledged interrupts when: 1. HW reported pointer is smaller than expected, and 2. Time from last update time (hdelta) is over half a buffer time. However, when HW reported pointer is only a few bytes smaller than expected, and when hdelta is just a little larger than half a buffer time (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged. The condition #2 uses jiffies, but jiffies is not high resolution since it is integer. We should consider jiffies inaccuracy.

2015-05-18sched: always use blk_schedule_flush_plug in io_schedule_outShaohua Li
block plug callback could sleep, so we introduce a parameter 'from_schedule' and corresponding drivers can use it to destinguish a schedule plug flush or a plug finish. Unfortunately io_schedule_out still uses blk_flush_plug(). This causes below output (Note, I added a might_sleep() in raid1_unplug to make it trigger faster, but the whole thing doesn't matter if I add might_sleep). In raid1/10, this can cause deadlock. This patch makes io_schedule_out always uses blk_schedule_flush_plug. This should only impact drivers (as far as I know, raid 1/10) which are sensitive to the 'from_schedule' parameter.

2015-05-18watchdog: Fix merge 'conflict'Peter Zijlstra
Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf665a62 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d293233 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again.

2015-05-18genirq: Don't suspend nested_thread irqs over system suspendNeilBrown
Nested IRQs can only fire when the parent irq fires. So when the parent is suspended, there is no need to suspend the child irq. Suspending nested irqs can cause a problem is they are suspended or resumed in the wrong order. If an interrupt fires while the parent is active but the child is suspended, then the interrupt will not be acknowledged properly and so an interrupt storm can result. This is particularly likely if the parent is resumed before the child, and the interrupt was raised during suspend. Ensuring correct ordering would be possible, but it is simpler to just never suspend nested interrupts.

2015-05-17rtnl/bond: don't send rtnl msg for unregistered ifaceNicolas Dichtel
Before the patch, the command 'ip link add bond2 type bond mode 802.3ad' causes the kernel to send a rtnl message for the bond2 interface, with an ifindex 0. 'ip monitor' shows: 0: bond2: <BROADCAST,MULTICAST,MASTER> mtu 1500 state DOWN group default link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 9: bond2@NONE: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN group default link/ether ea:3e:1f:53:92:7b brd ff:ff:ff:ff:ff:ff [snip] The patch fixes the spotted bug by checking in bond driver if the interface is registered before calling the notifier chain. It also adds a check in rtmsg_ifinfo() to prevent this kind of bug in the future.
