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/2018/3/7/621Signed-off-by:

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).

Commit 75a07f39 ("drm: rcar-du: Zero-out sg_tables when duplicating plane state") introduced a reference to the alpha field of struct rcar_du_vsp_plane_state that got removed in commit 301a9b8d ("drm/rcar-du: Convert to the new generic alpha property"). The issue stems from the merge of the two commits through separate branches and breaks compilation of the driver. Fix it.

The rcar_du_of_init() function is supposed to be defined as a stub when CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled in that case. However, a bug in the configuration option check makes it a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs from being fixed at boot time. Fix the configuration option check by using IS_ENABLED. Fixes: 81c0e3dd ("drm: rcar-du: Fix legacy DT to create LVDS encoder nodes") Signed-off-by:

This patch is in continuation to the "843e3c7d drm/amd/display: defer modeset check in dm_update_planes_state" where we started to eliminate the dependency on DRM_MODE_ATOMIC_ALLOW_MODESET to be set by the user space, which as such is not mandatory. After deferring, this patch eliminates the dependency on the flag for overlay planes. This has to be done in stages as its a pretty complex and requires thorough testing before we free primary planes as well from dependency on modeset flag. V2: Simplified the plane type check.

GFP_TRANSHUGE tries very hard to allocate huge pages, which can result in long delays with high memory pressure. I have observed firefox freezing for up to around a minute due to this while restic was taking a full system backup. Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT | __GFP_NORETRY instead, in order to fail quickly when there are no huge pages available. Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed up in the background if necessary. With these changes, I'm no longer seeing freezes during a restic backup.
