We set system_rev from an ATAG in our bootloader.... this trashes that

Is what we're doing there wrong or is overwriting system_rev here wrong?
That's an issue that was raised with the patch previously - see the
thread:
http://www.spinics.net/lists/arm-kernel/msg62218.html
I'd say you're not doing anything wrong and the patch should be updated.
In the meanwhile I adapted the patch slightly to keep the low 16 bits
from the ATAG, since it doesn't use them itself, and added some access
#defines to get the CPU type part or the ATAG part and changed the dozen
or so places in our code using system_rev to use those access defines.
I'm sure that won't satisfy anyone :-) but it lets me get on for now.
