[PATCH v2 00/12] perf tools: Add a script to sync the header copies with the kernel sources

[Arnaldo Carvalho de Melo <acme@kernel.org>]

Hi,

The tools/ tree carries copies of kernel headers that are refreshed by
hand: check-headers points at the stale ones, then one looks up the
kernel commits that changed each of them, pastes the relevant bits into
the commit message, regenerates the beauty string tables, builds the
consumers and commits, one header at a time.

This adds tools/perf/scripts/sync-headers.sh, also available as 'make -C
tools/perf sync-headers', and patches 2-12 are what it produced for this
branch: for each stale header it finds the kernel commits since the last
sync, copies the file, runs the beauty scripts before and after for the
beauty copies, builds perf and the other consumers of the header and
creates a commit in the usual format, grouping the headers that share a
consumer, as with the KVM ones.

As for the state of the copies, only two headers are newer in this branch
than in the kernel sources, perf_event.h and perf_regs.h: changes to them
go to tools/ first, with the kernel picking them up later, so the script
checks if the kernel file matches an earlier tools/ state and leaves
those alone.

Best regards,

- Arnaldo

What changed from v1 (e038fb24a0925576):

  PATCH 07/12, "perf beauty: Update copy of linux/socket.h with the
  kernel sources" [Mahe Tardy, <atk1cuJe3pqUvBya@gmail.com>]:

  - Added his Acked-by, no code change.

  v1 went out with just the files matching '000*.patch', which stops at
  0009, so patches 10/12 to 12/12 were never sent; they are all here now,
  sorry about that.
