The LOAD_REALMODE_ESP is defined under .code16 directive and will be used by 32-bit mode caller also. Is it ok because the instructions there will be same for both 16-bit and 32-bit? I checked https://ftp.gnu.org/old-gnu/Manuals/gas-2.9.1/html_chapter/as_16.html#SEC205 and don't find much information there.
