There are several functions at math64.h that are also defined at div64.c. As both are included at kernel-api.rst, Sphinx 3.x complains about symbol duplication: ./lib/math/div64.c:73: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'. Declaration is 'div_s64_rem'. ./lib/math/div64.c:104: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'. Declaration is 'div64_u64_rem'. ./lib/math/div64.c:144: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'. Declaration is 'div64_u64'. ./lib/math/div64.c:172: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'. Declaration is 'div64_s64'. In order to avoid Sphinx warnings about duplication, change the kernel-doc markups to just comments at math64.h.
