If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

All warnings (new ones prefixed by >>, old ones prefixed by <<):
WARNING: modpost: vmlinux: section mismatch in reference: mc_debug_data+0x0
(section: .data) -> mc_debug_data_early (section: .init.data)
With current infrastructure this is not easily fixable, as there is no way
to tag a percpu variable as __refdata.
