Reported-by: kernel test robot <lkp@intel.com>
All error/warnings (new ones prefixed by >>, old ones prefixed by <<):
>> WARNING: modpost: vmlinux.o(.text+0x27da8): Section mismatch in reference from the function r4k_cache_init() to the function .init.text:loongson2_sc_init()
The function r4k_cache_init() references
the function __init loongson2_sc_init().
This is often because r4k_cache_init lacks a __init
annotation or the annotation of loongson2_sc_init is wrong.
