'Commit 531d2410635c ("perf tools: Do not include stringify.h from the
kernel sources")' seems to have accidentially removed the inclusion of
"util/header.h" from "arch/powerpc/util/header.c".

"util/header.h" provides the prototype for get_cpuid() and is needed to
build perf on Powerpc.

	arch/powerpc/util/header.c:17:1: error: no previous prototype for
	‘get_cpuid’ [-Werror=missing-prototypes]
