Anders bisected this and found, # first bad commit: [cc34e658c6db493c1524077e95b42d478de58f2b] x86/boot: Move the early GDT/IDT setup code into startup/
Lore report link,
Thanks for the report. I'll look into this.
I've zapped cc34e658c6db from tip:x86/boot for the time being.
I have the same request as for the other patches applies, please split it up into ~3 patches for better bisectability and ease of review:
- first the mechanic movement of code, with very few changes (if the result builds & boots),
- then drop the RIP_REL_REF() uses in the second patch,
- and drop __head annotations in the third patch.
Thanks,
Ingo
