#     powerpc/ptrace: Split gpr32_set_common
#     
#     objtool reports the following warning:
#     
#       arch/powerpc/kernel/ptrace/ptrace-view.o: warning: objtool:
#         gpr32_set_common+0x23c (.text+0x860): redundant UACCESS disable
#     
#     gpr32_set_common() conditionally opens and closes UACCESS based on
#     whether kbuf pointer is NULL or not. This is wackelig.
#     
#     Split gpr32_set_common() in two fonctions, one for user one for
#     kernel.
#
