Hi folks,
After following kernel commit[1](find through bisect), We can see many sparse warnings like:
"

commit e0f244c63fc9d192dfd399cc2677bbdca61994b1

asmlinkage, module: Make ksymtab and kcrctab symbols and __this_module __visible
Make the ksymtab symbols for EXPORT_SYMBOL visible.
This prevents the LTO compiler from adding a .NUMBER prefix,
which avoids various problems in later export processing.
