Yes - later ARM binutils adds extra symbols like "$a" and "$d" to the symbol table as "mapping symbols" (binutils terminology). It's not clear whether these will continue to be visible via normal tools or not, and I was considering getting kallsyms to filter them out.
Depending on the outcome of the binutils side depends whether or not I end up modifying kallsyms to ignore these symbols and whether we end up saying "binutils earlier than <todays latest and greatest release> can not be used for ARM."
If a release of binutils is imminent which solves both the mapping symbol visibility problem and the undefined symbol issue, then I suspect its just all round easier to prevent the ARM kernel being built with older binutils versions.
