Small series for lib/bug.c:

  - Fix a KCSAN data race on bug->flags by using READ_ONCE/WRITE_ONCE
    and correcting the misleading comment about concurrency (patch 1).
  - Clean up const-correctness and bare 'unsigned' types (patch 2).
  - Add /sys/kernel/debug/bug_sites to inspect registered BUG/WARN
    sites and their runtime state, complementing the existing
    clear_warn_once interface (patch 3).

Build-tested with W=123.

Josh Law (3):
  lib/bug: annotate concurrent access to bug->flags with
    READ_ONCE/WRITE_ONCE
  lib/bug: clean up types in bug reporting helpers
  lib/bug: add debugfs interface to list all BUG/WARN sites
