I think someone mentioned on IRC, but this is missing Contributors and
Tested Kernels.

We had a lot of tapset additions -- briefly:

- Additional scsi probepoints
- Additional memory probepoints for kernel allocation and freeing.
- Additional ioblock and ioscheduler probepoints.
- Additional scheduler probepoints
- New IRQ and workqueue probepoints.
- New TTY probepoints.

- New task_time tapset to query time usage.
- New proc_mem tapset to query memory usage.

These could all probably use fuller descriptions, or maybe just point to
the documentation...
