[ Upstream commit 0de155752b152d6bcd96b5b5bf20af336abd183a ]
When CONFIG_PROC_FS is not set, proc_salinfo_show() is not used. Mark the
function as __maybe_unused to quieten the warning message.
../arch/ia64/kernel/salinfo.c:584:12: warning: 'proc_salinfo_show' defined but not used [-Wunused-function]
