[Intel Publishes "X86-S" Specification For 64-bit Only Architecture]( https://www.phoronix.com/news/Intel-X86-S-64-bit-Only )

Not booting from real mode (-> protected mode -> long mode) anymore.
Still seems to support running 32 bit applications on 64 bit kernel.

Wait, who wants to run 32 bit kernel on 64 bit processors?
How much silicon is saved with this new ISA?

@hyeyoo probably not much, but the bootloader/OS software can be simpler? Actually not, as it will have to support both old and new CPUs anyway, for many years.
Maybe the UEFI firmware then?
