Subject: [PATCH 02/95] Fix autofs compile without CONFIG_COMPAT
commit 3c761ea05a8900a907f32b628611873f6bef24b2 upstream.
The autofs compat handling fix caused a compile failure when
CONFIG_COMPAT isn't defined.
Instead of adding random #ifdef'fery in autofs, let's just make the
compat helpers earlier to use: without CONFIG_COMPAT, is_compat_task()
just hardcodes to zero.
We could probably do something similar for a number of other cases where
we have #ifdef's in code, but this is the low-hanging fruit.
