As described in include/linux/linkage.h,
FUNC -- C-like functions (proper stack frame etc.)
CODE -- non-C code (e.g. irq handlers with different, special stack etc.)
SYM_FUNC_{START, END} -- use for global functions
SYM_CODE_{START, END} -- use for non-C (special) functions
So use SYM_CODE_* to annotate exception handlers.
