Subject: [PATCH v3 1/3] kvm/powerpc: Export kvm exit reasons
To analyze the kvm exits with perf, we will need to map the exit codes
with the exit reasons. Such a mapping exists today in trace_book3s.h.
Currently its not exported to perf.
This patch moves these kvm exit reasons and their mapping from
"arch/powerpc/kvm/trace_book3s.h" to
"arch/powerpc/include/uapi/asm/trace_book3s.h".
Accordingly change the include files in "trace_hv.h" and "trace_pr.h".

Changes :
- Original patchset split into 2 patchsets now: for perf and powerpc
side changes.
