Jan Höppner 9697543396 s390/dasd: Fix zero write for FBA devices ... commit 709192d531 upstream. A discard request that writes zeros using the global kernel internal ZERO_PAGE will fail for machines with more than 2GB of memory due to the location of the ZERO_PAGE. Fix this by using a driver owned global zero page allocated with GFP_DMA flag set.
