    Don't require platform code to be #ifdeffed according to whether
    I2C is enabled or not ... if it's not enabled, let GCC compile out
    all I2C device declarations.  (Issue noted on an NSLU2 build that
    didn't configure I2C.)

  4. i2c-pca-isa: Add access check to legacy ioports

    When probing i2c-pca-isa writes to legacy ioports, which crashes the kernel
    if there is no device at that port.
    This patch adds a check_legacy_ioport call, so probe fails gracefully
    and thus prevents the oops.

    i2c: Storage class should be before const qualifier

    The C99 specification states in section 6.11.5:
    
    The placement of a storage-class specifier other than at the
    beginning of the declaration specifiers in a declaration is an

    ...
    
    This behavior has been confirmed by Marvell with a SATA analyzer.
    The Marvell port-multiplier apparently likes to see clean HOB
    information when accessing PMP registers.
    
    Since sata_mv uses PIO shadow register access, this doesn't happen
    automatically, as it might in a more purely FIS-based driver (eg. ahci).
    
    One way to fix this is to flag these commands with ATA_TFLAG_LBA48,
    forcing libata to write out the HOB fields with known (zero) values.

    libata: automatically use DMADIR if drive/bridge requires it

    Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir.
    
    That's nice, but most SATA devices which need it will tell us about it
    in their IDENTIFY PACKET response, as bit-15 of word-62 of the
    returned data (as per ATA7, ATA8 specifications).
    
    So for those which specify it, we should automatically use the DMADIR bit.
    Otherwise, disc writing will fail by default on many SATA-ATAPI drives.
    
    This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it
    if atapi_dmadir is set or identify data indicates DMADIR is necessary.
    atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting
    DMADIR.
    
    Original patch is from Mark Lord.

    The neigh_hash_grow() may update the tbl->hash_rnd value, which 
    is used in all tbl->hash callbacks to calculate the hashval.
    
    Two lookup routines may race with this, since they call the

    is changed with this lock write-locked moving the calls to ->hash
    under this lock read-locked closes this gap.

    [RTNL]: Validate hardware and broadcast address attribute for RTM_NEW…

    …LINK
    
    RTM_NEWLINK allows for already existing links to be modified. For this
    purpose do_setlink() is called which expects address attributes with a
    payload length of at least dev->addr_len. This patch adds the necessary
    validation for the RTM_NEWLINK case.
    
    The address length for links to be created is not checked for now as the
    actual attribute length is used when copying the address to the netdevice
    structure. It might make sense to report an error if less than addr_len
    bytes are provided but enforcing this might break drivers trying to be
    smart with not transmitting all zero addresses.

    When asked to blink LEDs the tg3 driver behaves when using:

    The default value for data is zero, and other drivers interpret this

  30. Add memory barrier semantics to wake_up() & co

    Oleg Nesterov and others have pointed out that on some architectures,
    the traditional sequence of
    
    	set_current_state(TASK_INTERRUPTIBLE);
    	if (CONDITION)
    		return;
    	schedule();
    
    is racy wrt another CPU doing
    
    	CONDITION = 1;
    	wake_up_process(p);
    
    because while set_current_state() has a memory barrier separating
    setting of the TASK_INTERRUPTIBLE state from reading of the CONDITION
    variable, there is no such memory barrier on the wakeup side.
    
    Now, wake_up_process() does actually take a spinlock before it reads and
    sets the task state on the waking side, and on x86 (and many other
    architectures) that spinlock is in fact equivalent to a memory barrier,
    but that is not generally guaranteed.  The write that sets CONDITION
    could move into the critical region protected by the runqueue spinlock.
    
    However, adding a smp_wmb() to before the spinlock should now order the
    writing of CONDITION wrt the lock itself, which in turn is ordered wrt
    the accesses within the spinlock (which includes the reading of the old
    state).
    
    This should thus close the race (which probably has never been seen in
    practice, but since smp_wmb() is a no-op on x86, it's not like this will
    make anything worse either on the most common architecture where the
    spinlock already gave the required protection).

    A "typical" implementation of atomic_add_unless() can return 0 immediately
