Subject: [RFC PATCH v2 01/26] tools include: Adopt byte ordering macros from byteorder/generic.h

From: Wang Nan <wangnan0@...wei.com>

This patch adopts the macros for byte order conversion from
"include/linux/byteorder/generic.h" to
"tools/include/linux/byteorder/generic.h"

tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.
