Subject: proc: make /proc/pid/limits world readable
From: Jiri Olsa <jolsa@redhat.com>

Having the limits file world readable will ease the task of system
management on systems where root privileges might be restricted.

Having admin restricted with root priviledges, he/she could not check
other users process' limits.

Also it'd align with most of the /proc stat files.
