anybody familiar with this error, or how to fix it ?
It doesnt seem to break anything (boots,runs fine),
but thats not much of a test.



[jimc@frodo b0-dd]$ make
  GEN     Makefile
  CALL    ../scripts/checksyscalls.sh
  DESCEND objtool
  INSTALL libsubcmd_headers
  LD      vmlinux.o
vmlinux.o: warning: objtool: .export_symbol+0x2c1d8: data relocation
to !ENDBR: stpcpy+0x0
  OBJCOPY modules.builtin.modinfo
...
make finishes

[jimc@frodo b0-dd]$ nm vmlinux.a | grep s7tpcpy
0000000000000050 r __export_symbol_stpcpy
0000000000000110 T stpcpy
00000000000000b0 d __UNIQUE_ID___addressable_stpcpy9

is it improper to EXPORT_SYMBOL a struct in a __section ?
