2016-08-29drm: Extract drm_encoder.[hc]Daniel Vetter
Same treatment as before. Only hiccup is drm_crtc_mask, which unfortunately can't be resolved until drm_crtc.h is less of a monster. Untangle the header loop with a forward declaration for that static inline.

2016-08-29powerpc: signals: Discard transaction state from signal framesCyril Bur
Userspace can begin and suspend a transaction within the signal handler which means they might enter sys_rt_sigreturn() with the processor in suspended state. sys_rt_sigreturn() wants to restore process context (which may have been in a transaction before signal delivery). To do this it must restore TM SPRS. To achieve this, any transaction initiated within the signal frame must be discarded in order to be able to restore TM SPRs as TM SPRs can only be manipulated non-transactionally.. >From the PowerPC ISA: TM Bad Thing Exception [Category: Transactional Memory] An attempt is made to execute a mtspr targeting a TM register in other than Non-transactional state.

Currently if none of the requested logical addresses can be claimed, the framework will fall back to the Unregistered logical address. Add a flag to enable this explicitly. By default it will just go back to the unconfigured state. Usually Unregistered is not something you want since the functionality is very limited. Unless the application has support for this, it will fail to work correctly. So require that the application explicitly requests this.

2016-08-17bus: arm-ccn: Correct required arguments for XP PMU eventsPawel Moll
XP can provide events from two sources: watchpoints, observing traffic on device ports and PMU looking at internal buses. Unfortunately the sysfs definition of the PMU events was requiring port number (instead of bus number) and direction (the buses are unidirectional), as these fields were shared with the watchpoint event. Although it does not introduce a major problem (port can be used as bus alias and direction is simply ignored for XP PMU events), it's better to fix it now, before external tools start depending on this behaviour.

2016-08-16PCI: Use positive flags in pci_alloc_irq_vectors()Christoph Hellwig
Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of certain interrupt types, pass positive flags like PCI_IRQ_LEGACY, PCI_IRQ_MSI, etc., to specify the acceptable interrupt types. This is based on a number of pending driver conversions that just happend to be a whole more obvious to read this way, and given that we have no users in the tree yet it can still easily be done. I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting all interrupt types very simple.

Move the documentation into Documentation/gpu, link it up and pull in the kernel doc. No actual text changes except that I did polish the kerneldoc a bit, especially for vga_client_register(). v2: Remove some rst from vga-switcheroo.rst that I don't understand, but which seems to be the reason why the new vgaarbiter.rst sometimes drops out of the sidebar index. v3: Drop one level of headings and clarify the vgaarb one a bit. v4: Fix some typos (Sean).

2016-08-16drm: Update connector documentationDaniel Vetter
- Shuffle docs from drm-kms.rst into the structure docs where it makes sense. - Put the remaining bits into a new overview section.

2016-08-16drm/doc: Include new drm_blend.cDaniel Vetter
There's not much point in kerneldoc if it's not included: - It won't show up in the pretty html pages. - The comments itself won't get parsed, which means 0day won't pick up changes, resulting in stale docs fast. Also, uapi really should be core, not helpers, so move drm_blend.c to that. That also means that the zpos normilize function loses it's helper status (and we might as well call it always). For that, EXPORT_SYMBOL. Just spotted while integrating docs and noticing that one was missing. With sphinx there's really no excuse any more to not build the docs and make sure it's all nice! $ make DOCBOOKS="" htmldocs Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1471034937-651-15-git-send-email-daniel.vetter@ffwll.ch

Pulls in quite a lot of connector related structures (cmdline mode, force/status enums, display info), but I think that all makes perfect sense. Also had to move a few more core kms object stuff into drm_modeset.h.

2016-08-09PCI: Update "pci=resource_alignment" documentationMathias Koehrer
Some uio based PCI drivers, e.g., uio_cif, do not work if the assigned PCI memory resources are not page aligned. By using the kernel option "pci=resource_alignment=<align>@<bus>:<slot>.<func>" it is possible to request page alignment for memory resources of devices. However, this is cumbersome when using several devices, and the bus/slot/func addresses may change if devices are added to or removed from the system. Extend the "pci=resource_alignment" option so we can specify the relevant devices via PCI vendor, device, subvendor, and subdevice IDs. The specification of the devices via IDs is indicated by a leading string "pci:" as argument to "pci=resource_alignment". The format of the specification is pci:<vendor>:<device>[:<subvendor>:<subdevice>] Examples: pci=resource_alignment=4096@pci:8086:9c22:103c:198f pci=resource_alignment=pci:8086:9c22 # defaults to PAGE_SIZE align [bhelgaas: changelog, use actual vendor/device IDs in examples] Signed-off-by: Mathias Koehrer <mathias.koehrer@etas.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
