From fa7252ed4d92397baf30e4a144af95a33eaa925b Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Fri, 19 Jan 2007 11:58:49 -0700 Subject: [PATCH] IB: Make sure struct ib_user_mad.data is aligned Make the untyped data region in ib_user_mad have type u64 so that it gets aligned properly. This avoids alignment faults in ib_umad when casting the data field to an rmpp_mad and accessing the 64-bit tid field on architectures like ia64.
