That spluttering noise is be choking on the title of this patch :)

Making these pseudo statics is in no way a cleanup. How about we just
say "they can't be static" and do something like:

/* Sorry, can't be static: that breaks archs which need these weak. */
#define DEFINE_PER_CPU(type, var) \
extern typeof(type) var; DEFINE_PER_CPU_SECTION(type, name, "")
