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

[ Upstream commit c816be7b5f24585baa9eba1f2413935f771d6ad6 ]

When we try to handle vmalloc faults, we can take a code
path which uses "code" before we actually set it.

Amusingly gcc-3.3 notices this yet gcc-4.x does not.
