Subject: [GIT] Sparc


1) Queued spinlocks and rwlocks for sparc64, from Babu Moger.

2) Some const'ification from Arvind Yadav.

3) LDC/VIO driver infrastructure changes to facilitate future
   upcoming drivers, from Jag Raman.

4) Initialize sched_clock() et al. early so that the initial printk
   timestamps are all done while the implementation is available and
   functioning.  From Pavel Tatashin.

Please pull, thanks a lot!
