One possibly dumb question and hope get some hints. 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.
