+Subject: autofs: work around unhappy compat problem on x86-64
+
+From: Ian Kent <raven@themaw.net>
+
+commit a32744d4abae24572eff7269bc17895c41bd0085 upstream.
+
+When the autofs protocol version 5 packet type was added in commit
+5c0a32fc2cd0 ("autofs4: add new packet type for v5 communications"), it
+obvously tried quite hard to be word-size agnostic, and uses explicitly
+sized fields that are all correctly aligned.
+
+However, with the final "char name[NAME_MAX+1]" array at the end, the
+actual size of the structure ends up being not very well defined:
+because the struct isn't marked 'packed', doing a "sizeof()" on it will
+align the size of the struct up to the biggest alignment of the members
+it has.
+
+And despite all the members being the same, the alignment of them is
+different: a "__u64" has 4-byte alignment on x86-32, but native 8-byte
+alignment on x86-64.  And while 'NAME_MAX+1' ends up being a nice round
+number (256), the name[] array starts out a 4-byte aligned.
+
+End result: the "packed" size of the structure is 300 bytes: 4-byte, but
+not 8-byte aligned.
+
+As a result, despite all the fields being in the same place on all
+architectures, sizeof() will round up that size to 304 bytes on
+architectures that have 8-byte alignment for u64.
+
+Note that this is *not* a problem for 32-bit compat mode on POWER, since
+there __u64 is 8-byte aligned even in 32-bit mode.  But on x86, 32-bit
+and 64-bit alignment is different for 64-bit entities, and as a result
+the structure that has exactly the same layout has different sizes.
+
+So on x86-64, but no other architecture, we will just subtract 4 from
+the size of the structure when running in a compat task.  That way we
+will write the properly sized packet that user mode expects.
+
+Not pretty.  Sadly, this very subtle, and unnecessary, size difference
+has been encoded in user space that wants to read packets of *exactly*
+the right size, and will refuse to touch anything else.

+Subject: compat: fix compile breakage on s390
+
+From: Heiko Carstens <heiko.carstens@de.ibm.com>
+
+commit 048cd4e51d24ebf7f3552226d03c769d6ad91658 upstream.
+
+The new is_compat_task() define for the !COMPAT case in
+include/linux/compat.h conflicts with a similar define in
+arch/s390/include/asm/compat.h.
+
+This is the minimal patch which fixes the build issues.

+Subject: Fix autofs compile without CONFIG_COMPAT
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+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.
