Subject: [PATCH v2 00/52] m68k: W=1 fixes
Hi all,
This patch series addresses the remaining (after [1]) warnings seen when
building arch/m68k/ with W=1. Perhaps surprisingly, this work has
identified and fixes a genuine bug in the Sun-3 TLB handling (see [PATCH
39/52]).
Most of the patches in these series are fairly trivial changes with a
very low risk of introducing any regressions. For the less trivial
patches, I did look at the assembler output before and after. As Arnd
is working actively on enabling W=1 rather sooner than later, and if no
one objects, I'm queueing these as fixes for v6.6.
Changes compared to v1[2]:
- Rebase against v6.6-rc1,
- Add Acked-by,
- Include "process.h" instead of <process.h>, to fix in-tree builds,
- Drop prefix from compiler output,
- Remove volatile and dedup casts, as suggested by Finn.
Note that this series does not address warnings on Coldfire or MMU-less
systems, but Greg is already taking care of those.
Thanks for your comments!

when I'm talking to journalists I just say "programmer" or something like that.
