Merge branch 'samsung/dt' into samsung/cleanup
Conflicts:
arch/arm/mach-s3c64xx/Makefile
arch/arm/mach-s5pc100/Makefile
arch/arm/mach-s5pv210/Makefile
Pull in previously resolved conflicts:
The Makefiles were reorganized in the "rmk/restart" series and modified
in the "samsung/cleanup series". This also pulls in the other conflict
resolutions from the restart series against the samsung/dt series.
