      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.

      Restore direct_io / truncate locking API · 37fbf4bf
      Anton Altaparmakov authored
      With kernel 3.1, Christoph removed i_alloc_sem and replaced it with
      calls (namely inode_dio_wait() and inode_dio_done()) which are
      EXPORT_SYMBOL_GPL() thus they cannot be used by non-GPL file systems and
      further inode_dio_wait() was pushed from notify_change() into the file
      system ->setattr() method but no non-GPL file system can make this call.
      
      That means non-GPL file systems cannot exist any more unless they do not
      use any VFS functionality related to reading/writing as far as I can
      tell or at least as long as they want to implement direct i/o.
      
      Both Linus and Al (and others) have said on LKML that this breakage of
      the VFS API should not have happened and that the change was simply
      missed as it was not documented in the change logs of the patches that
      did those changes.
      
      This patch changes the two function exports in question to be
      EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible
      for all modules.
      
      Christoph, who introduced the two functions and exported them GPL-only
      is CC-ed on this patch to give him the opportunity to object to the
      symbols being changed in this manner if he did indeed intend them to be
      GPL-only and does not want them to become available to all modules.

      ARM: OMAP2: fix mailbox init code · 655850ed
      Ohad Ben-Cohen authored
      Fix this:
      
      arch/arm/mach-omap2/mailbox.c: In function 'omap2_mbox_probe':
      arch/arm/mach-omap2/mailbox.c:354: error: 'omap2_mboxes' undeclared (first use in this function)
      arch/arm/mach-omap2/mailbox.c:354: error: (Each undeclared identifier is reported only once
      arch/arm/mach-omap2/mailbox.c:354: error: for each function it appears in.)
      
      Which happens on CONFIG_ARCH_OMAP2 && !CONFIG_SOC_OMAP2420, due to
      missing omap2_mboxes declaration.
      
      In addition, make sure we declare the right mailbox instances for 2430.
