In AMDGPU driver, the bo mapping should always align to CPU page or the page table is corrupted. The first patch is cherry-picked from Loongson community, which sets a suitable dev_info.gart_page_size so Mesa will handle the alignment correctly. The second patch is added to ensure an ioctl with unaligned parameter to be rejected -EINVAL, instead of causing page table corruption. The patches should be applied for drm-next.
