Proposing a 64-bit only x86 arch (tentatively x86-S) is all well and good, but wow Intel still hasn't gotten over AMD creating 64-bit x86 (AMD64/x86-64):

Since its introduction over 20 years ago, the Intel® 64 architecture became the dominant operating mode.
No, the 64-bit architecture Intel introduced was Itanium (IA-64). That was also jointly developed by HP, based on their PA-RISC arch. It crashed and burned.
This is admittedly rather minor, but it irritates me to an almost irrational degree.
@win8linux even less important but the hell is going on with "using 5-level pages requires disabling paging"? it sounds like they're saying "to do this thing, simply don't"
@nasado @win8linux I believe that's referring to the eldrich wizardry that is configuring paging mode on x86. I'm not up to speed on 5-level paging exactly, but you might need to downgrade from 4-level paging to segmentation and then upgrade to 5-level paging from there.
