Sparse warns about missing declarations for these functions:
+arch/powerpc/kernel/syscall_64.c:108:23: warning: symbol
'syscall_exit_prepare' was not declared. Should it be static?
+arch/powerpc/kernel/syscall_64.c:18:6: warning: symbol 'system_call_exception'
was not declared. Should it be static?
+arch/powerpc/kernel/syscall_64.c:200:23: warning: symbol
'interrupt_exit_user_prepare' was not declared. Should it be static?
+arch/powerpc/kernel/syscall_64.c:288:23: warning: symbol
'interrupt_exit_kernel_prepare' was not declared. Should it be static?
Add declaration for them.
