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 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Anton Blanchard <anton@samba.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Tested-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com>
