	This adds (in req-gen/) a framework for defining gpci counter requests. It uses macro magic similar to ftrace. Also convert the existing hv-gpci request structures and enum values to use the new framework (and adjust old users of the structs and enum values to cope with changes in naming). In exchange for this macro disaster, we get autogenerated event listing for GPCI in sysfs, build time field offset checking, and zero duplication of information about GPCI requests.

2014-03-24	powerpc/perf: Add a shared interface to get gpci version and capabilities	Cody P Schafer
	This exposes a simple way to grab the firmware provided collect_priveliged, ga, expanded, and lab capability bits. All of these bits come in from the same gpci request, so we've exposed all of them. Only the collect_priveliged bit is really used by the hv-gpci/hv-24x7 code, the other bits are simply exposed in sysfs to inform the user.
