I haven't fixed this ARM64 bisection breakage yet, but I've integrated & backmerged all the other fixes and changes, and pushed it out to the WIP branch: # 1755441e323b per_task: Implement single template to define 'struct task_struct_per_task' fields and offsets git://git.kernel.org/pub/scm/linux/kernel/git/mingo/tip.git sched/headers Let me know if there's anything missing or if there's a new breakage. This is pretty close to what will be -v2. Thanks, Ingo
