Subject: [ppc64] export last_pid
Message-id: 11955970291160-do-send-email-smoser@redhat.com
O-Subject: [PATCH RHEL5u2] bz253208 Cell/B.E. Kernel Maintenance [2/4]
Bugzilla: 253208

Export last_pid for use in /proc/spu-loadavg

The /proc/spu-loadavg file, provided by the spufs module, requires the
last_pid variable to be exported.

This change adds an EXPORT_SYMBOL_GPL for this.
