tools, perf: Fix up for x86 UAPI disintegration

[David Howells <dhowells@redhat.com>]

Hi,

I've posted a revised version of my perf patches to my UAPI disintegration GIT
tree.  If you look here:

	http://git.infradead.org/users/dhowells/linux-headers.git/shortlog/refs/tags/uapi-perf-x86-20121105

you can see the result.

To construct this, I did the following:

 (1) Created a branch (perf-uapi) at v3.7-rc4.

 (2) Merged tipbot's perf/core branch into that.

 (3) Added a patch to export asm/svm.h, asm/vmx.h and asm/perf_regs.h from the
     x86 arch so that the disintegration scripts will deal with them.

     This is at the x86-bits tag.

 (4) Added a patch to manually export and disintegrate linux/hw_breakpoint.h.

 (5) Rebased and updated a pair of patches to make the tools Makefile use a
     defined function to handle descent into tools directories.

 (6) Rebased and updated the patch to fix perf for x86.

     This is at the perf-uapi-20121105 tag.

 (7) Re-disintegrated the x86 UAPI on top of the x86-bits tag to make sure
     that the headers exported in (3) get processed.

     This is on the disintegrate-x86 branch at tag disintegrate-x86-20121105.

 (8) Merged the disintegrate-x86 branch in to the working branch.

     This is at the uapi-perf-x86-20121105 branch.

perf builds successfully as:

	make O=~+/foo tools/perf
	make O=~+/foo -C tools perf
	make O=~+/foo -C tools/perf

at points (6) and (8).

It doesn't seem that I can post the patches, given there is a pair of merge
commits in the series.  If it is desirable, then I can drop the top merge
commit and post the patches.  For information, attached is a pull request for
the patches between the two merge commits.
