thank for you reply.
of course it won't, i just think it is better to splite the global
data between irq-gic and irq-gic-v3.
I wrote some hook module for gic, kallsyms_lookup_name can't support
for mutlipte symbol,
i need to call kallsyms scan to get the addr.
If you think it isn't necessary, well for me.

zou cao
