Jan Blunck 632bbfeee4 [PATCH] trigger a syntax error if percpu macros are incorrectly used ...

get_cpu_var()/per_cpu()/__get_cpu_var() arguments must be simple
identifiers.  Otherwise the arch dependent implementations might break.

This patch enforces the correct usage of the macros by producing a syntax
error if the variable is not a simple identifier.
