kbuild: lto: add _mcount to list of used symbols
Some randconfig builds fail with undefined references to _mcount when CONFIG_TRIM_UNUSED_KSYMS is set: ERROR: modpost: "_mcount" [drivers/tee/optee/optee.ko] undefined! ERROR: modpost: "_mcount" [drivers/fsi/fsi-occ.ko] undefined! ERROR: modpost: "_mcount" [drivers/fpga/dfl-pci.ko] undefined! Since there is already a list of symbols that get generated at link time, add this one as well. Fixes: fbe078d397b4 ("kbuild: lto: add a default list of used symbols") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
