Suka has also posted a fix for this with a different approach [1]. Can 
you please ack/pull one of these versions? Building perf is broken on 
v4.3-rc due to this.

I did not get any answer for additional comments I made to the patch
(couldnt get marc.info working, sending the patch again)

Hi Jiri,
I concur with the changes you proposed to my patch here (getting rid of 
the weak variant):
http://article.gmane.org/gmane.linux.kernel/2046108

I am aware of the other approach you posted (and the one attached 
below). When I said "please ack/pull one of these versions", I meant one 
of: your version, Suka's and mine.

I was hoping somebody could test it on ppc ;-)

I think the last version (in my last email) that keeps the weak
variable is correct, let's wait for Arnaldo to sort this out

I just tried it, but it fails. As Suka points out in his patch:
"Adding perf_regs.o to util/Build unconditionally, exposes a 
redefinition error for 'perf_reg_value()' function (due to the static 
inline version in util/perf_regs.h). So use #ifdef 
HAVE_PERF_REGS_SUPPORT' around that function."

could you (or Suka) please reply in here with the patch?

thanks,
jirka
