#     scripts/kallsyms: change table to store (strcut sym_entry *)
#     
#     The symbol table is extended every 10000 addition by using realloc(),
#     where data copy might occur to the new buffer.
#     
#     To decrease the amount of possible data copy, let's change the table
#     to store the pointer.
#     
#     The symbol type + symbol name part is appended at the end of
#     (struct sym_entry), and allocated together with the struct body.

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.
