On s390, the vmexit event has a tree-like structure: between exit_event_begin and exit_event_end several other events may happen and with each of them refining the previous ones. This patch adds a decoder for such events to the generic code and also the files <asm/kvm_perf.h> and kvm-stat.c for s390. Commands 'perf kvm stat record', 'report' and 'live' are supported.
