It seems that backporting the mentioned commit verbatim would also require 2da37761671b5bdedbe04e6469cfa57cd6b6ae45 ("powerpc/32: Fix objtool unannota= ted intra-function call warnings") to make SYM_FUNC_START_LOCAL/SYM_FUNC_END available. Please drop= this patch from 6.1 and older for now. Adding Christophe and Michael to cc. Is backporting the additional patch an= option (and if so, for which kernel versions?), or should I send a new patch that does not use SYM_FUNC_START_LOCAL/SYM_FUNC_END for stable?
