__ex_table ends up with two entries:

0010 10000000 0a000000 12000000 0a000000 ................
The first is for the __put_user in .text (extable_not_init()) and the second is
for the one in .init.text (init()).
Depending on how the module gets allocated, the one referring to .init.text
may be first or last.
Hmm, I understand now. The problem is that we don't know which entries
are for __init, and which are not...
(You can see here why we haven't fixed this: exceptions in __init in modules
are rare, perhaps non-existent).
Agreed.
Is it possible to put extable for __init in a separate section?
Thanks for your explanation!
