* Linux 5.10 introduces a new lockless ringbuffer. The new ringbuffer
is structured completely different to the previous iterations.
Add support for retrieving the ringbuffer from debug information
and/or using vmcoreinfo. The new ringbuffer is detected based on
the availability of the "prb" symbol.
* Support newer kernels as follows:
- 5.10, 5.11, 5.12 (x86_64 SPARSEMEM)
