Subject: [x86_64] EXPORT smp_call_function_single
Message-id: 47EBF10A.9060103@redhat.com
O-Subject: [PATCH RHEL5.2] EXPORT smp_call_function_single
Bugzilla: 438720

This resolves BZ#438720

This is a simple backport of 64a26a731235b59c9d73bbe82c1f896d57400d37

Please note that smp_call_function_single is already exported on ia64
and i386.

The recent LSPP security certification has raised significant interest
with our DoD customers; this was an oversight and is needed to offer
all of ProPack.

Please ACK.
