I doubt anyone uses it on anything else than some low cost x86 netbooks.
I removed __packed and did a small test today (download 10mb of garbage, check
md5)
- it doesn't seem to affect driver (on staging-testing, without this patchset).
Nevertheless I would prefer to leave it like that for this patch set if it's
OK with you and perhaps include it for next series I'll work on.
