Chris Metcalf 1ca1a4cf59 connector: improved unaligned access error fix ... In af3e095a1f, Erik Jacobsen fixed one type of unaligned access bug for ia64 by converting a 64-bit write to use put_unaligned(). Unfortunately, since gcc will convert a short memset() to a series of appropriately-aligned stores, the problem is now visible again on tilegx, where the memset that zeros out proc_event is converted to three 64-bit stores, causing an unaligned access panic. A better fix for the original problem is to ensure that proc_event is aligned to 8 bytes here. We can do that relatively easily by arranging to start the struct cn_msg aligned to 8 bytes and then offset by 4 bytes. Doing so means that the immediately following proc_event structure is then correctly aligned to 8 bytes. The result is that the memset() stores are now aligned, and as an added benefit, we can remove the put_unaligned() calls in the code.
