2014-07-16perf kvm: Add stat support on s390Alexander Yarygin
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.

2014-07-16perf kvm: Use defines of kvm eventsAlexander Yarygin
Currently perf-kvm uses string literals for kvm event names, but it works only for x86, because other architectures may have other names for those events. To reduce dependence on architecture, we add <asm/kvm_perf.h> file with defines for: - kvm_entry and kvm_exit events, - exit reason field name in kvm_exit event, - length of exit reasons strings, - vcpu_id field name in kvm trace events, and replace literals in perf-kvm.
