I accept the patch because it un-breaks support for ARM cpus, and I 
prefer a working fix to a perfect fix in this specific, transitional, 
situation.

However a general rework of ARM timer code is in order so that all SoCs 
and CPUs share the same set of gd variables with the same names and the 
same logic; and when we get that, this code shall move along.

About this rework, as the saying goes... "Patches Welcome ©". :)
