The first problem is that these SETGET macros lose typing information, and therefore can't see the 'packed' attribute and therefore take unaligned access SIGBUS signals on sparc64 when trying to derefernce the member. The next problem is a similar issue in btrfs_name_hash(). This gets passed things like &key.offset which is a member of a packed structure, losing this packed'ness information btrfs_name_hash() performs a potentially unaligned memory access, again resulting in a SIGBUS.
