  "message": "[IA64] Squeeze ticket locks back into 4 bytes.\n\nLinus pointed out that other people have spent large amounts of time\nand effort to optimize the layout of frequently used structures. Often\nthese have embedded locks, and the assumption is that a lock takes\n4 bytes.  Linus also pointed out how to work with the limited options\nfor atomic instructions on Itanium.\n\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n",
