[patch 00/16] Remove old style lock initializers

[Thomas Gleixner]

The old style lock initializers SPIN_LOCK_UNLOCKED and
RW_LOCK_UNLOCKED are deprecated for several years. The series fixes
the remaining users and removes the defines.

Thanks,

It should be safe as the spinlocks cannot be access until after the
following ppc_md pointer initialisations are done (and all this happens
before the secondary CPUs are started).

But, you are right that there is nothing like actually testing with
iSeries. :-)
