Have you tested this ?
It doesn't build for me:
arch/powerpc/perf/hv-24x7.c: In function 'catalog_read':
arch/powerpc/perf/hv-24x7.c:223:3: error: format '%d' expects argument of type
'int', but argument 2 has type 'uint64_t' [-Werror=format]
cc1: all warnings being treated as errors
I'll fix that up in my tree.
Cheers,
Ben.
