These are lots of device drivers that include machine specific header files from ARM platforms and that are not easily scriptable. The changes have been found through manual inspection and should cause no visible changes because of the build script that maps the old names to the new ones.
And you end up missing a bunch of drivers in the process, such as the sa1100 RTC driver which is shared between sa11x0 and PXA. I wonder how many of the Samsung platforms get broken by this as well...
In any case, what we _should_ be doing here as well is moving the headers included by drivers for platform data out of the arch/arm/mach/ subtrees and into include/linux/platform_data. That will substantially reduce the amount of mach/ headers to deal with.
Where I want this to get to is not a persistence of the existing crappy situation where platforms stuff platform data definitions into arch/arm, but instead put them in the right place. That means providing them with a good reason why the existing solution won't work, and not allowing mach/ includes in drivers is a very good way to achieve that.
