[PATCH 09/11] xen/platform_op: Wrap around XENPF_mem_hotadd

[Jiqian Chen <Jiqian.Chen@xxxxxxx>]

Wrap around call stack functions of XENPF_mem_hotadd:
memory_add
        mem_hotadd_check
        valid_numa_range
        extend_frame_table
                setup_frametable_chunk
        setup_m2p_table
                m2p_mapped
                setup_compat_m2p_table
                        alloc_hotadd_mfn
        share_hotadd_m2p_table
        transfer_pages_to_heap
        destroy_m2p_mapping
                destroy_compat_m2p_mapping
        cleanup_frame_table
                hotadd_mem_valid
