[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?

My dream tonight was really strange: I was kidnapped and forced to do kernel work, and then I was sold to a software company.

I've been never... brave enough for doing slides on the plane on the way to conference, so here we go, ahead of the travel to Vancouver: https://ossna2023.sched.com/event/2b02a776f0e49c787af92b1d1847622e
Hopefully I'll be just adding some last minute developments from the respective LSF/MM session to report in my LinuxCon track talk. And hopefully those developments will include "we agreed to remove SLAB, nobody objected" ;)
