Michael Ellerman 02a771c9a6 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: 7e92e01b72 ("powerpc: Provide syscall wrapper")
