A bit redundant and very poor style argument alignment
Make sure your tab indentation is set to 8.

	fault = handle_mm_fault(mm, vma, address,
				flags | (fault_code & FAULT_CODE_WRITE));

though perhaps fault_code could be unsigned and
perhaps you could use the same style initializer
for fault_code as patch 19/20.
