[XenPPC] What does the PAPR macro?

[Christian Ehrhardt <ehrhardt@xxxxxxxxxxxxxxxxxx>]

Hi,
I'm curently implementing H_PERFMON and found some code in the file 
arch/powerpc/of_handler/papr.S which is not clear for me by just reading 
it ;)
I "guessed" this line together for H_PERFMON based on the other lines 
around there, but what would the following line really do?
"PAPR(5, 1,papr_h_perfmon, H_PERFMON)"
Is it correct and if not why?
I assume it's some kind of registering xen implemented papr hooks right?
