Subject: [PATCH 4/4] modules: Add missing entry for __ex_table

From: Helge Deller <[email protected]>

The entry for __ex_table was missing, which may make __ex_table
become 1- or 2-byte aligned in modules.
Add the entry to ensure it gets 32-bit aligned.

Cc'ing stable was overkill, I'll remove it.
