Subject: [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.
