Even if they only have one # single callsite - it looks like gcc may have decided that the code was # unlikely, and not worth inlining. # # The code generation difference is harmless, but caused a few new section # mismatch errors, since the (now no longer inlined) function wasn't in # the __init section, but called other init functions: # # Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem() # Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap() # Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap() # # So add the appropriate __init annotation to make modpost not complain. # In both cases there were trivially just a single callsite from another # __init function. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> #
