linux-next: manual merge of the drm tree with the tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Dave,

Today's linux-next merge of the drm tree got conflicts in
drivers/gpu/drm/ttm/ttm_bo.c between commits
ad49f501867cba87e1e45e5ebae0b12435d68bf1 ("drm/ttm/radeon: add dma32
support") and c96e7c7a3a79931446ecf9494a8415e4d164ebd8 ("drm/ttm: Read
buffer overflow") from Linus' tree and commit
a987fcaa805fcb24ba885c2e29fd4fdb6816f08f ("ttm: Make parts of a struct
ttm_bo_device global") from the drm tree.

I fixed it up (see below) and can carry the fix as necessary.
