Subject: [38/74] SECURITY: selinux, fix update_rlimit_cpu parameter

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jiri Slaby <jirislaby@...il.com>

commit 17740d89785aeb4143770923d67c293849414710 upstream.

Don't pass current RLIMIT_RTTIME to update_rlimit_cpu() in
selinux_bprm_committing_creds, since update_rlimit_cpu expects
RLIMIT_CPU limit.

Use proper rlim[RLIMIT_CPU].rlim_cur instead to fix that.
