[PATCH 3/4] powerpc/pseries: RTAS work area requires GENERIC_ALLOCATOR

[Randy Dunlap]

The RTAS work area allocator uses code that is built by
GENERIC_ALLOCATOR, so the PSERIES Kconfig should select the
required Kconfig symbol to fix multiple build errors.

powerpc64-linux-ld: arch/powerpc/platforms/pseries/rtas-work-area.o: in function `.rtas_work_area_allocator_init':
