    gcc-10: mark more functions __init to avoid section mismatch warnings · e99332e7
    Linus Torvalds authored
    It seems that for whatever reason, gcc-10 ends up not inlining a couple
    of functions that used to be inlined before.  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.
