binfmt_misc has a mount point in the middle of the sysctl and that mount point
is created as a proc_generic directory.

Doing it that way gets in the way of cleaning up the sysctl proc support as it
continues the existence of a horrible hack.  So instead simply create the
directory as an ordinary sysctl directory.  At least that removes the magic
special case.

[akpm@osdl.org: warning fix]
