Subject: [GIT PULL] UAPI: perf fixes on top of perf/urgent


Hi Arnaldo,

Here are my perf fixes based on top of your perf/urgent branch.  I have
squashed the linux/hw_breakpoint.h disintegration patch into the main perf
patch as you can't have one without the other without getting errors.

I tried to apply Xiao Guangrong's builtin-kvm fixes for the x86/x86_64-only
bits, but they weren't simple to fix up - so I left them off.

So, if you could pull the perf-uapi-20121119 tag, this contains:
 
 (1a) A patch to export asm/svm.h, asm/vmx.h and asm/perf_regs.h to UAPI.

 (1b) A merge commit for (1a).  The patch in (1a) 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.

     Could you possibly merge patch (1a) rather than cherry-picking it?  That
     would mean that my disintegrate-x86 branch won't conflict with yours.

 (2) The three tools patches from me plus Sukadev Bhattiprolu's powerpc patch
     to use uapi/unistd.h that you have added to perf/core already.

 (3) A patch that does:

     (a) Exports and disintegrates linux/hw_breakpoint.h.

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

     Neither of these parts works without the other, so I've combined them into
     one to maintain bisectability.

If you look on the perf-uapi branch in the GIT tree mentioned below, you'll see
that for convenience, I have added an extra bit beyond the tag mentioned below
whereby the disintegrate-x86 branch is merged and tagged as
uapi-perf-x86-20121119-2.
