#     modpost: do not set ->preloaded for symbols from Module.symvers
#     
#     Now that there is no overwrap between symbols from ELF files and
#     ones from Module.symvers.
#     
#     So, the 'exported twice' warning should be reported irrespective
#     of where the symbol in question came from. Only the exceptional case
#     is when __crc_<sym> symbol appears before __ksymtab_<sym>. This
#     typically occurs for EXPORT_SYMBOL in .S files.
