Benjamin Walsh bd94d98255 arm: add connecting exceptions at runtime ... Add sys_exc_connect() (and its x86-compatible alias nanoCpuExcConnect()) that allows connecting an exception handler at runtime. The current implementation is a bit of a bastard, to avoid disturbing the current implementation of the exception handlers. Instead of hooking _exc_wrapper() in all vectors and adapting the exception handlers, the current exception handlers are still hooked directly in the vectors. When an exception is hooked at runtime, _exc_wrapper() gets installed in the vector and the real handler gets inserted in _sw_exc_table; this means that the scheme only works with non-XIP kernels. This should be enhanced so that _exc_wrapper() is hooked in all vectors, and that current exception handlers (for faults mostly) are reworked to be inserted in the _sw_exc_table and wrapped in _exc_wrapper().
