Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: global cleanups" from Arnd Bergmann:
"Quite a bit of code gets removed, and some stuff moved around, mostly
the old samsung s3c24xx stuff. There should be no functional changes
in this series otherwise. Some cleanups have dependencies on other
arm-soc branches and will be sent in the second round.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>"
Fixed up trivial conflicts mainly due to #include's being changes on
both sides.
