_systemtap_ rebased to version 3.3 The _systemtap_ packages have been upgraded to upstream version 3.3, which provides a number of bug fixes and enhancements: * Limited support for the extended Berkeley Packet Filter (eBPF) tracing on the Intel64 and AMD64 architectures has been added. Use the `--runtime=bpf` option to use eBPF as a backend. Due to numerous limitations of `eBPF` and its SystemTap interface, only simple scripts work. For more information, see the Knowledge article https://access.redhat.com/articles/3550581 and the stapbpf(8) manual page. * The `--sysroot` option has been optimized for cross-compiled environments. * A new `--example` option allows you to search the example scripts distributed with SystemTap without providing the whole path of the file. * The SystemTap runtime and tapsets are compatible with kernel versions up to 4.17. * Usage of SystemTap on systems with real time kernel or machines with a high number of CPUs has been improved. * Handling of code used for Spectre and Meltdown attack mitigation has been improved.
