[PATCH 00/52] m68k: W=1 fixes

[Geert Uytterhoeven <geert@linux-m68k.org>]

	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 plan to rebase [1] and this series after the release of
v6.6-rc1, and send it as a fixes pull request to Linus.

Note that this series does not address warnings on Coldfire or MMU-less
systems.

Thanks for your comments!

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.
