Subject: [PATCH]  Centralize the macro definition of "__packed".


  Centralize the attribute macro definition of "__packed" so no
subsystem has to do that explicitly.

Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>

---

  compile tested to make sure the HFS subsystem still builds.  now
there's just 50 gazillion usages of "__attribute__((packed))" that can
be tightened up.
