#     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.

WARNING: vmlinux.o(.text+0x2fc8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
