drm/amdkfd: CRIU Save Shared Virtual Memory ranges

Browse source

During checkpoint stage, save the shared virtual memory ranges and
attributes for the target process. A process may contain a number of svm
ranges and each range might contain a number of attributes. While not
all attributes may be applicable for a given prange but during
checkpoint we store all possible values for the max possible attribute
types.
