It's been self-hosting for a few days now. That is, it runs on IBT enabled hardware (Tigerlake) and is capable of building the next kernel. It is also almost clean on allmodconfig using GCC-11.2. The biggest TODO item at this point is Clang, I've not yet looked at that. Patches are also available here: git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git x86/wip.ibt This series is on top of tip/master along with the linkage patches from Mark: https://lore.kernel.org/all/20220216162229.1076788-1-mark.rutland@arm.com/ Enjoy!
