2018-05-18drm/nouveau/secboot: remove VLA usageGustavo A. R. Silva
In preparation to enabling -Wvla, remove VLA. In this particular case directly use macro NVKM_MSGQUEUE_CMDLINE_SIZE instead of local variable cmdline_size. Also, remove cmdline_size as it is not actually useful anymore. The use of stack Variable Length Arrays needs to be avoided, as they can be a vector for stack exhaustion, which can be both a runtime bug or a security flaw. Also, in general, as code evolves it is easy to lose track of how big a VLA can get. Thus, we can end up having runtime failures that are hard to debug. Also, fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621 Signed-off-by: Gustavo A. R.

2018-05-18drm/nouveau: nouveau: use larger buffer in nvif_vmm_mapArnd Bergmann
gcc points out a buffer that is clearly too small to be used in a meaningful way, as the 'sizeof(*args) + argc > sizeof(stack)' will always fail: In function 'memcpy', inlined from 'nvif_vmm_map' at drivers/gpu/drm/nouveau/nvif/vmm.c:55:2: include/linux/string.h:353:9: error: '__builtin_memcpy' offset 40 is out of the bounds [0, 16] of object 'stack' with type 'u8[16]' {aka 'unsigned char[16]'} [-Werror=array-bounds] return __builtin_memcpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/nouveau/nvif/vmm.c: In function 'nvif_vmm_map': drivers/gpu/drm/nouveau/nvif/vmm.c:40:5: note: 'stack' declared here This makes the buffer large enough so it should serve the purpose that the author presumably had in mind. Alternatively we could just get rid of it completely and simplify the code at the cost of always doing the kmalloc (as we do in the current version).

2018-05-17drm/tegra: Move fbdev unmap special caseDaniel Stone
User framebuffers are created with either bo->pages or bo->vaddr set, depending on whether or not an IOMMU is present. On the other hand, the framebuffer created for fbdev emulation has a vaddr mapping made if bo->pages is set after creation. This is set up in fbdev probe. Remove the special case unmapping from the general-purpose framebuffer destroy, and move it to fbdev teardown.

2018-05-17drm/tegra: Adding new typedef vm_fault_tSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Reference id -> 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_page() returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_page() will replace this inefficiency by returning VM_FAULT_* type.

2018-05-17gpu: host1x: Acquire a reference to the IOVA cacheThierry Reding
The IOVA API uses a memory cache to allocate IOVA nodes from. To make sure that this cache is available, obtain a reference to it and release the reference when the cache is no longer needed. On 64-bit ARM this is hidden by the fact that the DMA mapping API gets that reference and never releases it. On 32-bit ARM, this is papered over by the Tegra DRM driver (the sole user of the host1x API requiring the cache) acquiring a reference to the IOVA cache for its own purposes. However, there may be additional users of this API in the future, so fix this upfront to avoid surprises.
