#     powerpc/64s: Fix section mismatch warnings from setup_rfi_flush()
#     
#     The recent LPM changes to setup_rfi_flush() are causing some section
#     mismatch warnings because we removed the __init annotation on
#     setup_rfi_flush():
#     
#       The function setup_rfi_flush() references
#       the function __init ppc64_bolted_size().
#       the function __init memblock_alloc_base().
#     
#     The references are actually in init_fallback_flush(), but that is
#     inlined into setup_rfi_flush().
#     
#     These references are safe because:
#      - only pseries calls setup_rfi_flush() at runtime
#      - pseries always passes L1D_FLUSH_FALLBACK at boot
#      - so the fallback flush area will always be allocated
#      - so the check in init_fallback_flush() will always return early:
#        /* Only allocate the fallback flush area once (at boot time). */
#        if (l1d_flush_fallback_area)
#        	return;
#     
#      - and therefore we won't actually call the freed init routines.
#     
#     We should rework the code to make it safer by default rather than
#     relying on the above, but for now as a quick-fix just add a __ref
#     annotation to squash the warning.
#
