Subject: [PATCH] [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.
