powerpc/pseries: hcall_exit tracepoint retval should be signed
The hcall_exit() tracepoint has retval defined as unsigned long. That
leads to humours results like:
bash-3686 [009] d..2 854.134094: hcall_entry: opcode=24
bash-3686 [009] d..2 854.134095: hcall_exit: opcode=24 retval=18446744073709551609
It's normal for some hcalls to return negative values, displaying them
as unsigned isn't very helpful. So change it to signed.
bash-3711 [001] d..2 471.691008: hcall_entry: opcode=24
bash-3711 [001] d..2 471.691008: hcall_exit: opcode=24 retval=-7
Which can be more easily compared to H_NOT_FOUND in hvcall.h
