6984ee797a [POWERPC] Fix cell's mmio nvram to properly parse device tree
The mmio nvram driver (used by cell only atm) isn't properly parsing
the device-tree, meaning that nvram isn't found correctly on the new
Cell blades.  It works ok for old blades where the nvram is at the
root of the device tree but fails on Malta and CAB when it's hanging
off axon.  This fixes it by using the proper OF parsing functions.

a7f67bdf2c [POWERPC] Constify & voidify get_property()
Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

powerpc core changes.

34af946a22 [PATCH] spin/rwlock init cleanups
locking init cleanups:

 - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
 - convert rwlocks in a similar manner

this patch was generated automatically.

Motivation:

 - cleanliness
 - lockdep needs control of lock initialization, which the open-coded
   variants do not give
 - it's also useful for -rt and for lock debugging in general

edf03c1ee8 [PATCH] powerpc: move mmio_nvram.c over to arch/powerpc
The nvram code formally known as bpa_nvram.c is rather
generic really, so it is quite likely to be useful to
future boards not based on cell.

This patch puts it into arch/powerpc/sysdev.
