Hi Arnaldo,

Assuming my patches should be based on your perf/core branch, could you pull
from my git tree at tag perf-uapi-20121108 into your perf/core branch?

Note the tree also contains a uapi-perf-x86-20121108 tag that has the UAPI
disintegration branch for x86 merged on top for reference.

There are six commits, three preliminary patches:

 (1) A patch to export asm/svm.h, asm/vmx.h and asm/perf_regs.h to UAPI.

 (2) A merge for (1) - the patch in (1) is premerged by the UAPI disintegration
     for x86 also, and I'd rather not include your perf/core branch in that if
     I can avoid it.

 (3) A patch to export and disintegrate linux/hw_breakpoint.h.  It looks like
     it should perhaps have been exported already, given the __KERNEL__ markers
     in it.

and then the main three patches:

 (4) Use a makefile $(call ...) function in tools/Makefile to make it easier
     to deal with.

 (5) Fix handling of O= with a relative path when doing something like:

	make tools/perf O=foo

     from the top-level directory in the kernel source tree for all tools.

 (6) Make perf work for x86 by adding -I flags and changing long #includes
     with "../../include" in them into short <asm/foo.h> type things.

David
