Except for:

    kernel/locking/spinlock.c:306:9: error: implicit declaration of
    function '__raw_write_lock_nested'; did you mean
    '_raw_write_lock_nested'? [-Werror=implicit-function-declaration]
      306 |         __raw_write_lock_nested(lock, subclass);
          |         ^~~~~~~~~~~~~~~~~~~~~~~
          |         _raw_write_lock_nested

Which was also reported for other architectures:

Gr{oetje,eeting}s,

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
