Subject[PATCH] autofs: fix 3.3-rc5 compilation breakage on x86-32
Recent commit a32744d4abae24572eff7269bc17895c41bd0085 broke autofs
compilation on x86-32:

fs/autofs4/inode.c: In function ‘autofs4_fill_super’:
fs/autofs4/inode.c:228: error: implicit declaration of function ‘is_compat_task’

This patch fix that by adding #if checks.

Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com>
