2017-02-02drm: meson: rename driver name to meson-drmNeil Armstrong
The platform driver name is currently "meson" which can lead to some confusion, this patch renames it to "meson-drm" and removes the owner attribute since is always added by __platform_driver_register called by the module_platform_driver() macro.

2017-02-02drm/etnaviv: add cmdbuf suballocatorLucas Stach
There are 3 big benefits to suballocating a single big DMA buffer for command submission: 1. Avoid hammering CMA. The old way of allocating and freeing a DMA buffer for each submission was hitting some of the real slow pathes in CMA, as this allocator was not designed for a concurrent small buffers load. 2. Less TLB flushes on IOMMUv2. If a new command buffer is mapped into the GPU address space the MMU TLBs need to be flushed. By having one big buffer statically mapped to the GPU, a lot of those flushes can be avoided. 3. No funky workarounds for GC3000. The FE TLB flush on GC3000 isn't reliable. To work around that we tried to lay out the cmdbufs in the GPU address space in a way to avoid this issue. This hasn't always worked if the address space is crowded. A single statically mapped buffer avoids the erratum completely. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2017-02-02drm/etnaviv: always flush MMU TLBs on map/unmapLucas Stach
This ensures that the GPU isn't able to write into already freed objects, as doing this in the IOVA reaper isn't enough, as the gem_free_object path will also cause unmaps to happen. On MMUv2 this also ensures that stale entries, which may have been prefetched into the TLB will be purged. The flush is low overhead, as it gets batched up with the next user command buffer, so this isn't incuring an overhead for each buffer map/unmap.

2017-02-01efi/fdt: Avoid FDT manipulation after ExitBootServices()Ard Biesheuvel
Some AArch64 UEFI implementations disable the MMU in ExitBootServices(), after which unaligned accesses to RAM are no longer supported. Commit: abfb7b686a3e ("efi/libstub/arm*: Pass latest memory map to the kernel") fixed an issue in the memory map handling of the stub FDT code, but inadvertently created an issue with such firmware, by moving some of the FDT manipulation to after the invocation of ExitBootServices(). Given that the stub's libfdt implementation uses the ordinary, accelerated string functions, which rely on hardware handling of unaligned accesses, manipulating the FDT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.

Pull networking fixes from David Miller: 1) Fix handling of interrupt status in stmmac driver. Just because we have masked the event from generating interrupts, doesn't mean the bit won't still be set in the interrupt status register. From Alexey Brodkin. 2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha. 3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich. 4) cls_flow does not match on icmpv6 codes properly, from Simon Horman. 5) Initial MAC address can be set incorrectly in some scenerios, from Ivan Vecera. 6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(), from Dan Carpenter. 7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet. 8) Fix crash in iwlwifi when unregistering thermal zone, from Jens Axboe. 9) Check for DMA mapping errors in starfire driver, from Alexey Khoroshilov. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (31 commits) tcp: fix 0 divide in __tcp_select_window() ipv6: pointer math error in ip6_tnl_parse_tlv_enc_lim() net: fix ndo_features_check/ndo_fix_features comment ordering net/sched: matchall: Fix configuration race be2net: fix initial MAC setting ipv6: fix flow labels when the traffic class is non-0 net: thunderx: avoid dereferencing xcv when NULL net/sched: cls_flower: Correct matching on ICMPv6 code ipv6: Paritially checksum full MTU frames net/mlx4_core: Avoid command timeouts during VF driver device shutdown gianfar: synchronize DMA API usage by free_skb_rx_queue w/ gfar_new_page net: ethtool: add support for 2500BaseT and 5000BaseT link modes can: bcm: fix hrtimer/tasklet termination in bcm op removal net: adaptec: starfire: add checks for dma mapping errors net: phy: micrel: KSZ8795 do not set SUPPORTED_[Asym_]Pause can: Fix kernel panic at security_sock_rcv_skb net: macb: Fix 64 bit addressing support for GEM stmmac: Discard masked flags in interrupt status register net/mlx5e: Check ets capability before ets query FW command net/mlx5e: Fix update of hash function/key via ethtool ...

If user tries to initialize uinput device mixing old and new style initialization (i.e. using old UI_SET_ABSBIT instead of UI_ABS_SETUP, we forget to allocate input->absinfo and will crash when trying to send absolute events: ioctl(ui, UI_DEV_SETUP, &us); ioctl(ui, UI_SET_PHYS, "Test"); ioctl(ui, UI_SET_EVBIT, EV_ABS); ioctl(ui, UI_SET_ABSBIT, ABS_X); ioctl(ui, UI_SET_ABSBIT, ABS_Y); ioctl(ui, UI_DEV_CREATE, 0); Reported-by: Rodrigo Rivas Costa <rodrigorivascosta@gmail.com> Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=191811 Fixes: fbae10db0940 ("Input: uinput - rework ABS validation") Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
