[VIRT-339 # ARMv8.5-BTI, Branch Target Identification ] Updated to match the latest kernel for-next/bti-user branch; I hope this is going to be merged for 5.7. Posted v9 for review. [VIRT-349 # QEMU SVE2 Supprt ] More RISU work to improve support for SVE. Stephen Long has posted some sve2 risu patterns that need reviewing, and I plan to test all of that next week vs ArmIE. I had a start on rebasing my current sve2 patch set on master, with lots of prereqs merged. But stopped in the middle because I realized that I wanted to get all of the RISU work done first, so that I can test each patch as it is updated. r~ PS: Out all next week on holiday.
