2.6.28-stable review patch. If anyone has any objections, please let us know. ------------------ (cherry picked from eb64f1e8cd5c3cae912db30a77d062367f7a11a6) walk_shadow assumes the caller verified validity of the pdptr pointer in question, which is not the case for the invlpg handler. Fixes oops during Solaris 10 install.
