From: Pu Wen <puwen@xxxxxxxx> [ Upstream commit 4787eff3fa88f62fede6ed7afa06477ae6bf984d ] The tool perf is useful for the performance analysis on the Hygon Dhyana platform. But right now there is no Hygon support for it to analyze the KVM guest os data. So add Hygon Dhyana support to it by checking vendor string to share the code path of AMD.
