[PATCH v2 0/4] powerpc/rtas: exports and locking

[Nathan Lynch <nathanl@linux.ibm.com>]

This series began as a single patch[1] to convert the RTAS subsystem's
internal locks to raw spinlocks. The discussion of that patch
identified opportunities to update a few aspects of the RTAS API, so
the series begins with those and ends with a rebased version of the
original patch.

Changes since v1:
- Unexport the singleton 'rtas' struct.
- Remove lock and args fields from 'struct rtas_t', making them
  private to the RTAS subsystem.
- Convert all symbol exports in rtas.c to EXPORT_SYMBOL_GPL.
