#     powerpc/32: Select ARCH_SPLIT_ARG64
#     
#     On 32-bit kernels, 64-bit syscall arguments are split into two
#     registers. For that to work with syscall wrappers, the prototype of the
#     syscall must have the argument split so that the wrapper macro properly
#     unpacks the arguments from pt_regs.
#     
#     The fanotify_mark() syscall is one such syscall, which already has a
#     split prototype, guarded behind ARCH_SPLIT_ARG64.
#     
#     So select ARCH_SPLIT_ARG64 to get that prototype and fix fanotify_mark()
#     on 32-bit kernels with syscall wrappers.
#     
#     Note also that fanotify_mark() is the only usage of ARCH_SPLIT_ARG64.
#     
#     Fixes: 7e92e01b7245 ("powerpc: Provide syscall wrapper")
