drm/gpusvm: Introduce devmem_only flag for allocation
This commit adds a new flag, devmem_only, to the drm_gpusvm structure. The
purpose of this flag is to ensure that the get_pages function allocates
memory exclusively from the device's memory. If the allocation from
device memory fails, the function will return an -EFAULT error.
Required for shared CPU and GPU atomics on certain devices.
v3:
- s/vram_only/devmem_only/
Fixes: 99624bdff867 ("drm/gpusvm: Add support for GPU Shared Virtual Memory")
