* [PATCH] perf tools: remove .. in perf includes/

  To: acme; +Cc: linux-kernel, Andi Kleen

From: Andi Kleen <ak@linux.intel.com>

The perf user space has a lot of includes with ugly .. chains. This also
makes it impossible to include any perf files from other code.

I think the original reason for this were some wrapper include files
for the kernel includes, and the explicit paths were needed to avoid
endless recursion. A better way to handle this is #include_next

- Add all the relevant directories as -I in the Makefile
- Remove (near) all the .. in include statements
- Remove unnecessary wrappers that do nothing
- Fix up some fallout

This makes the code more pleasant to read.

I did it all in one big patch to keep bisectability.

It builds, but breaks this:

I mean jusst the:

part, the other one (kernelversion), if you fix, double brownie points
to ya :-)

Hmm cannot reproduce. The extra tarball builds fine and includes memset_64.S
with my patch on Linus latest.
