      three kbuild fixes for 3.3:
       - make deb-pkg symlink race fix.
       - make coccicheck fix.
       - Dropping the check for modutils.  This is not a regression, but
         allows the module-init-tools replacement kmod work with the 3.3
         kernel.
      
      * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
        coccicheck: change handling of C={1,2} when M= is set
        builddeb: Don't create files in /tmp with predictable names
        kbuild: do not check for ancient modutils tools

      autofs: work around unhappy compat problem on x86-64 · a32744d4
      Ian Kent authored
      When the autofs protocol version 5 packet type was added in commit
      5c0a32fc
      
       ("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.

      One InfiniBand/RDMA regression fix for 3.3:
      
       - mlx4 SR-IOV changes added static exported functions, which doesn't
         build on powerpc at least.  Fix from Doug Ledford for this.
