Brian Atkinson becc717f61 Adding ZERO_PAGE detection ... On some architectures ZERO_PAGE is unavailable because it references a GPL exported symbol of empty_zero_page. Originally e08b993 removed the call to PAGE_ZERO(0) for assignment to the abd_zero_page. However, a simple check can be done to avoid a kernel allocation and free for the abd_zero_page if ZERO_PAGE is available.
