 * Registers a user callback function that will be called when the memory object is deleted and its

 * function on a callback stack associated with memobj. The registered user callback functions are
 * called in the reverse order in which they were registered. The user callback functions are called
 * and then the memory object is deleted and its resources freed. This provides a mechanism for the
 * application (and libraries) using memobj to be notified when the memory referenced by host_ptr,
 * specified when the memory object is created and used as the storage bits for the memory object,
 * can be reused or freed.
 *
 * The application may not call CL api's with the cl_mem object passed to the pfn_notify.

 * The type associated with a 2D image created from a buffer in an OpenCL program is image2d_t.
 * Both the sampler and sampler-less read_image built-in functions are supported for 2D images
 * and 2D images created from a buffer.  Similarly, the write_image built-ins are also supported
 * for 2D images created from a buffer.
 *
 * When the 2D image from buffer is created, the client must specify the width,
 * height, image format (i.e. channel order and channel data type) and optionally the row pitch
 *
 * The pitch specified must be a multiple of CL_DEVICE_IMAGE_PITCH_ALIGNMENT pixels.
 * The base address of the buffer must be aligned to CL_DEVICE_IMAGE_BASE_ADDRESS_ALIGNMENT pixels.

/* This extension adds a new function that allows for direct memory import into
 * OpenCL via the clImportMemoryARM function.
 *
 * Memory imported through this interface will be mapped into the device's page
 * tables directly, providing zero copy access. It will never fall back to copy
 * operations and aliased buffers.
 *
 * Types of memory supported for import are specified as additional extension
 * strings.
 *
 * This extension produces cl_mem allocations which are compatible with all other
 * users of cl_mem in the standard API.
 *
 * This extension maps pages with the same properties as the normal buffer creation
 * function clCreateBuffer.
