Exotic architecture fixes

Exotic architecture fixes

[Geert Uytterhoeven]

I created a branch where I collected several exotic architecture fixes
(and a few
other trivial fixes):

  git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k.git
exotic-arch-fixes

Several of these have been ack'ed (cfr. *-indicators below).
If you reject any of the commits, please scream.
If you want to take any of them yourself, please do so.

I intend to merge this into my for-next branch after the release of v3.10-rc4,
and ask Linus to pull after the release of v3.10-rc5.
This branch may be rebased.

Thanks!

Rebased against v3.10-rc3.

JFYI, this has a trivial conflict with "CRIS: drop unused Kconfig symbols"
in -next.

I inserted a revert of Arnd's 8c090cfbf980581454ae4caae731574fedd7dce8
("staging/solo6x10: depend on CONFIG_FONTS") before this one.

I merged this in the for-next branch of my repo.

Stephen: cris/for-next and m68k/for-next removed two different hunks from
arch/cris/arch-v32/drivers/Kconfig. To resolve the conflict, just remove both.
Thanks!

Surely, your for-linus branch would have been a better choice.  And then
maybe merge that into your for-next branch if you really needed these
fixes to continue with m68k work?

An updated version is now in for-linus, as Linus has pulled the m68k
content on the
old for-linus branch.

This one handles both upper and lower case hex characters, while hex2bin()
handles lower case only. Is that OK, or should hex2bin be extended?
