    [PATCH] swsusp: do not use memcpy for snapshotting memory
    
    swsusp should not use memcpy for snapshotting memory, because on some
    architectures memcpy may increase preempt_count (i386 does this when
    CONFIG_X86_USE_3DNOW is set).  Then, as a result, wrong value of preempt_count
    is stored in the image.
    
    Replace memcpy in copy_data_pages with an open-coded loop.
