Bug#669028: please backport new procfs hidepid option into 3.2

[Romain Francoise <rfrancoise@debian.org>]

Source: linux-2.6
Severity: wishlist

The procfs hidepid option added in Linux 3.3 can be useful as an
additional step to secure multi-user systems and I would like to have it
in wheezy's kernel.

At first glance, the following commits from mainline would need to be
backported:

 97412950b1 ("procfs: parse mount options")
 0499680a42 ("procfs: add hidepid= and gid= mount options")
 a2ef990ab5 ("proc: fix null pointer deref in proc_pid_permission()")
 99663be772 ("proc: fix mount -t proc -o AAA")

All these apply cleanly (in order) on top of v3.2.15, although I did not
check that the result actually works.

Thanks!
