Subject: [RFC 06/11] perf hists: Make a room for hazard info in struct hist_entry
From: Madhavan Srinivasan <maddy@...ux.vnet.ibm.com>
To enable hazard mode with perf report (followup patch) we need to
have cpu pipeline hazard data available in hist_entry. Add hazard
info into struct hist_entry. Also add hazard_info as parameter to
hists__add_entry().
