        - Removed redundant #include statements

- Changes in previous submissions -
        - Removed unused statistics.
        - General clean up - removed unused variables and macros.
 - Incorporated following comments from Ben Hutchings
        - No need to restart the interface in vxge_ethtool_sset
        - Do not use #ifdef ADVERTISED_XX
        - Remove unnecessart intermediate copy in vxge_ethtool_gdrvinfo
        - Use strlcpy() to ensure null-termination.
        - Use ethtool_op_get_tso, ethtool_op_set_tx_hw_csum instead
          of redefining the same code.
        - Implement get_strings_count instead of deprecated get_stats_count.
        - Don't report reporting the EEPROM length as we don't supprt
          get/set eeprom.

703da5a1a2 Neterion: New driver: Main entry points
This patch implements all the driver entry point functions.
- Definition of all module loadable paramters.
- Implementation of all driver entry point functions.

- Changes in this submission -
        - Fixed compilation error when enabling debug statements
        - Fixed few warnings when CONFIG_PCI_MSI is not defined
        - Removed unnecessary volatile variables
        - Removed compare_ether_addr as it causes unaligned memory access on
          the sparc64 platform.

- Changes in previous submissions -
        - As per Stephen Hemminger's comments removed the following loadable
          parameters - gro, rx_& tx max_indicate_pkts, exec_mode, rx & tx
          pause_enable, tx_steering_type and intr_type.
        - Added Device ID definition in vxge-main.h instead of
          include/linux/pci_ids.h file - Reported by David Miller
 - Incorporated following review comments from Ben Hutchings
        - NAPI is always enabled (no option to turn it OFF).
        - Loadable parameters
         rx_steering_type: This loadable option is removed.
         ring_blocks: This loadable option is removed.
         The driver default settings work well in most if not all cases.
         Another patch to configure these parameters with ethtool will be
         released in the future.
 - LRO has been deprecated in favour of GRO - Bill Fink & Dave Miller's comment
 - Fixed sparse warnings - Reported by Andi Kleen
 - Removed unused variables

66d97fedea Neterion: New driver: register set - vxge-reg.h
- Complete Register map details of Neterion Inc's X3100 Series 10GbE PCIe I/O
  Virtualized Server Adapter.

- No change from previous submission.

- Changes in previous submissions -
- Incorporated following comments from Ben Hutchings
        - Use original macros for endian checks
        - Remove VXGE_OS_PLATFORM_* macros as they are unused.
        - Converted multiple bVALX macros into single with additional

        - Using __packed instead of pragma pack(1)
        - Added a comment of the use of a hw swapper so driver code is
          portable (does not have to change the byte order for register
          access as well as dma operations) on different ENDIAN platforms.

7e765cb4a0 sfc: Call netif_napi_add() before registering our interrupt handler
If we use a shared legacy IRQ then our interrupt handler may be called
as soon as it is registered even though IRQs are disabled on the NIC.
Now that the legacy interrupt handler also checks for event delivery,
it may decide to schedule polling in this case.  Ensure that the NAPI
context is valid but disabled at this point.

424b86a6bc netfilter: xtables: fix IPv6 dependency in the cluster match
This patch fixes a dependency with IPv6:

ERROR: "__ipv6_addr_type" [net/netfilter/xt_cluster.ko] undefined!

This patch adds a function that checks if the higher bits of the
address is 0xFF to identify a multicast address, instead of adding a
dependency due to __ipv6_addr_type(). I came up with this idea after
Patrick McHardy pointed possible problems with runtime module
dependencies.

2f181855a0 gso: Fix support for linear packets
When GRO/frag_list support was added to GSO, I made an error
which broke the support for segmenting linear GSO packets (GSO
packets are normally non-linear in the payload).

These days most of these packets are constructed by the tun
driver, which prefers to allocate linear memory if possible.
This is fixed in the latest kernel, but for 2.6.29 and earlier
it is still the norm.

Therefore this bug causes failures with GSO when used with tun
in 2.6.29.

87e1960e93 i2c-piix4: Add support to SB800 SMBus changes
Add support for the AMD SB800 Family series of products.
Major changes include the changes to addressing the SMBus registers at different
location from the locations in the previous compatible parts from AMD such as
SB400/SB600/SB700. For SB800, the main features and register definitions of
SMBus and other interfaces are still compatible with the previous products with
the only change being in how to access the internal registers for these blocks.

2378bc09b9 i2c-algo-pca: Use timeout for checking the state machine
We now timeout also if the state machine does not change within the
given time. For that, the driver-specific completion-functions are
extended to return true or false depending on the timeout. This then
gets checked in the algorithm.

bac3e7c2aa i2c: Adapt debug macros for KERN_* constants
According to kerneljanitors todo list all printk calls (beginning

Those are the changes to the debug macros in the i2c subsystem
to meet this requirement. Also changing no-debug statements
to raw printks again.

8a52c6b4d5 i2c: Adapter timeout is in jiffies
i2c_adapter.timeout is in jiffies. Fix all drivers which thought
otherwise. It didn't really matter as long as the value was only used
inside the driver, but soon i2c-core will use it too so it must have
the proper unit.

Note: for the i2c-mpc driver, this fixes a bug in polling mode.
Timeout would trigger after 1 jiffy, which is most probably not what
the author wanted.

8fcfef6e65 i2c: Set a default timeout value for all adapters
Setting a default timeout value on a per-algo basis doesn't make any
sense. Move the default value setting to i2c-core. Individual adapter
drivers can specify a different (non-zero) value if they wish.

Also express the timeout value in a way which results in the same
duration regarless of the value of HZ.

94d78e180c i2c-algo-pcf: Handle timeout correctly
With a postfix decrement these timeouts reach -1 rather than 0, but after the
loop it is tested whether they have become 0.

As pointed out by Jean Delvare, the msg_num should be tested before the timeout.
With the current order, you could exit with a timeout error while all the
messages were successfully transferred.
