[ Upstream commit d02a3a2cb25d384005a6e3446a445013342024b7 ]
nsm_use_hostnames is a module parameter and it will be exported to sysctl procfs. This is to let user sometimes change it from userspace. But the minimal unit for sysctl procfs read/write it sizeof(int). In big endian system, the converting from/to bool to/from int will cause error for proc items.
This patch use a new proc_handler proc_dobool to fix it.
