[PATCH 1/3] drm/amdgpu/ttm: constify static vm_operations_struct
The only usage of amdgpu_ttm_vm_ops is to assign its address to the vm_ops field in the vm_area_struct struct. Make it const to allow the compiler to put it in read-only memory.

[PATCH 0/3] drm/ttm: constify static vm_operations_structs
Constify a few static vm_operations_struct that are never modified. Their only usage is to assign their address to the vm_ops field in the vm_area_struct, which is a pointer to const vm_operations_struct. Make them const to allow the compiler to put them in read-only memory. With this series applied, all static struct vm_operations_struct in the kernel tree are const.
