proc: mark more files as permanent
Mark
/proc/devices
/proc/kpagecount
/proc/kpageflags
/proc/kpagecgroup
/proc/loadavg
/proc/meminfo
/proc/softirqs
/proc/uptime
/proc/version
as permanent /proc entries, saving alloc/free and some list/spinlock ops
per use.
These files are never removed by the kernel so it is OK to mark them.
