Subject: [PATCH 2/5] perf beauty: Move prctl.h files (uapi/linux and x86's) copy out of the directory used to build perf
From: Arnaldo Carvalho de Melo <acme@...hat.com>
It is used only to generate string tables, not to build perf, so move it
to the tools/perf/trace/beauty/{include,arch}/ hierarchies, that is used
just for scraping.
This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.
No other tools/ living code uses it, just <linux/usbdevice_fs.h> coming
from either 'make install_headers' or from the system /usr/include/
directory.
