In handling the H_CEDE hypercall, if this vcpu has already been prodded (with the H_PROD hypercall, which Linux guests don't in fact use), we branch to a numeric label '1f'. Unfortunately there is another '1:' label before the one that we want to jump to. This fixes the problem by using a textual label, 'kvm_cede_prodded'. It also changes the label for another longish branch from '2:' to 'kvm_cede_exit' to avoid a possible future problem if code modifications add another numeric '2:' label in between.

Finally we can kill the 'sync_supers' kernel thread along with the '->write_super()' superblock operation because all the users are gone. Now every file-system is supposed to self-manage own superblock and its dirty state. The nice thing about killing this thread is that it improves power management. Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up every 5 seconds no matter what - even if there were no dirty superblocks and even if there were no file-systems using this service (e.g., btrfs and journalled ext4 do not need it). So it was wasting power most of the time. And because the thread was in the core of the kernel, all systems had to have it. So I am quite happy to make it go away. Interestingly, this thread is a left-over from the pdflush kernel thread which was a self-forking kernel thread responsible for all the write-back in old Linux kernels. It was turned into per-block device BDI threads, and 'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.
