960b6f657c92adab4931653f9dc0e94ed5da1975 # Author: Michael Ellerman <mpe@ellerman.id.au> # Date: Thu Apr 5 22:39:34 2018 +1000 # # 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. # # Fixes: abf110f3e1ce ("powerpc/rfi-flush: Make it possible to call setup_rfi_flush() again") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # <
