Ok, so I now have the first fix merged, but what's the next step here?
As you say, the x86 ARCH_SYSCALL_EXIT_WORK is now entirely unused.
It's called ARCH_SYSCALL_WORK_EXIT these days, but that's for the SYSCALL_WORK_SYSCALL_xyz flags, not for the TIF_xyz ones.
Revert? Or does somebody have a fix patch?
