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

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

From: Russell King <[email protected]>

commit a9ad21fed09cb95d34af9474be0831525b30c4c6 upstream.

When SMP_ON_UP is used and the spinlocks are inlined, we end up with
inline spinlocks in the exit code, with references from the SMP
alternatives section to the exit sections.  This causes link time
errors.  Avoid this by placing the exit sections in the init-discarded
region.
