[PATCH] uml: fix page faults in SKAS3 mode.
I hadn't been running a SKAS3 host when testing the "uml: fix hang in TT mode on fault" patch (commit 546fe1cbf91d4d62e3849517c31a2327c992e5c5), and I didn't think enough to the missing trap_no in SKAS3 mode. In fact, the resulting kernel doesn't work at all in SKAS3 mode.
