Subject: [PATCH v2 0/2] MIPS: Fix check_bugs() modpost warning

Hi all,

This series fixes a modpost warning visible in -next from check_bugs()
and helps avoid a potential, albeit unlikely, warning from
check_bugs_early().

---
Changes in v2:
- Now two separate patches: one to avoid current check_bugs() warning
  and one to avoid potential check_bugs_early() warning.
- Sink body of check_bugs_early() into setup_arch() directly, rather
  than marking it as __init (Nick).
- Add Naresh's reported-by to patch 1, which came after v1 was sent.
- Reword commit messages to note that there is not a problem at run time
  because check_bugs() and check_bugs_early(), while not marked __init,
  are only called from __init functions; modpost does not know this
  though, hence the warning.
- Link to v1: https://lore.kernel.org/r/20230419-mips-check_bugs-init-attribute-v1-1-91e6eed55b89@kernel.org
